The Lloyd’s of London building is an essential centrepiece of the London Central Business District. Recognised with Grade 1 listed status, the building’s facade is a prominent example of Britain’s modern architectural style in the last half a century, creating a contrast to the country’s significant historical buildings. Alimak Service’s Cento team, in partnership with BMU manufacturer Manntech, recently replaced the tired facade access system to continue the maintenance of the Richard Rogers designed building into the future.
The pre-existing 35-year-old building maintenance units (BMUs) had been in place since the Lloyds building’s completion in 1985. This project saw challenges, including the requirement of replacement without pausing daily operations of the internal offices and trading floor, while navigating the needs of working on a heritage-listed building and considering the loading limits of the building.
Alimak Service’s Cento team was integral in the implementation process to overcome these challenges, having previously provided maintenance and service solutions for the original facade access system on the Lloyds building. This Cento Engineering Group was recently acquired by Alimak Group, however had worked alongside Alimak Service as a service operator in the UK for 20 years, providing installation, maintenance, spare parts, and inspections to facade access systems. The team’s specific knowledge of the building was used to plan the complex BMU replacement effectively. The new system was installed with multiple crane lifts and innovative working approaches such as a suspended scaffold platform; coordinated by the expert Alimak Service technicians.
As a result, Alimak Service’s Cento team together with Manntech delivered a custom facade access solution consisting of 17 building maintenance units in total. Of the 17, six underslung BMUs were installed on the underside of concrete capping beams. A further four track-mounted BMUs utilised the pre-existing track system with the addition of telescopic jibs. Six larger crane-type BMUs are mounted on the building’s feature towers. Finally, a single crane-type BMU with a telescopic jib was installed above the atrium section, with a bespoke design required to minimise total weight.
Installation of Building Maintenance Units on existing, long-established buildings and structures always presents specific challenges. Commonly, issues are associated with the lack of construction equipment on-site for heavy lifting and the time pressures of completing work with the minimum disruption to everyday business.
As the service provider for the Alimak Group, consisting of the leading names in the vertical access industry such as CoxGomyl, Alimak Service is uniquely qualified to deliver custom service solutions for any project. This was recently demonstrated during the installation of a replacement BMU for the 200 Clarendon building (formerly known as the John Hancock Tower) in Boston.
The Building Maintenance Unit (BMU) had to be positioned in a designated parking area around the existing track in the centre of the roof. The additional complications of antennas, heating, ventilation and air conditioning (HVAC) equipment made an installation by helicopter or derrick crane unfeasible. Therefore, the BMU itself was designed to present manageable parts which could be transported to the roof via the elevators. This still left a 25-metre journey from the roof hatch to the installation site with HVAC equipment blocking a clear path, with antennas and wires also making a route around the units impractical.
A rigging scaffold was designed to facilitate direct transport of the BMU parts into position by hoisting over HVAC units. Time was a significant factor, and the rigging scaffold was therefore equipped with two beams and two motorised trollies. This allowed two crews to work simultaneously with one group lifting the BMU parts through the hatch while the second crew worked on BMU assembly in the parking area.
The BMU crossbar middle section and platform presented an additional challenge in that, at 11 metres and 20 metres respectively, they could not be transported via the elevators. The Alimak Service team, therefore, developed a solution using the old BMU to lift the crossbar under the platform area with special outriggers used to lift it into place.
To lift the platform, the new BMU had to be partially commissioned to make use of the hoist functionality. The wire ropes were lowered to ground level with tensioning weights attached to mullion guides. There, the wire ropes were connected to the platform and a weight test was performed. This allowed for operators to safely board the platform during the hoisting process to monitor the mullion guides.
Both of these complex installation procedures were each completed in a day and the installation as a whole was completed in under two weeks.

1271 Avenue of the Americas, previously known as the Time & Life Building, is an important historic part of the American built environment. In 1959 it became the first of four new towers which expanded the iconic Rockefeller Center. Reaching 587 feet (179 metres) and 48 floors, the green glass facade remains a vibrant part of New York City life to this day.
When it became clear a modern new facade access system was required to protect this jewel in the Manhattan cityscape, CoxGomyl were entrusted with developing and executing a carefully considered building access solution appropriate to the special requirements of installation on an existing structure, and all within a tight time frame. This type of BMU replacement project brings with it specific challenges which together the CoxGomyl and Alimak Service team (the installers) are well experienced in navigating.
Drawing on a range of installation methods and pre-planned strategies, Alimak Service were able to deliver an improved facade access solution with prompt and smooth delivery. The comprehensive facade access system for 1271 Avenue of the Americas encompasses two CoxGomyl Building Maintenance Units which were selected and adapted for the parameters of the building throughout design, manufacture and installation.
The first BMU is located at the eighth-floor terrace. A compact design was a critical requirement due to an existing garage structure which the BMU would be housed within when in parked position. Throughout the process, the garage dimensions were considered to ensure the BMU could be practically stored. The compact design also allowed for smooth installation with the use of an 80-ton street crane.
The second Building Maintenance Unit is situated at roof level. In order to achieve the required functionality, precise planning was required to transport the BMU to its permanent position. All components were calculated in size and weight to be transported through the building using the existing elevators, bringing them as far as a loading dock one level below the roof itself. From there, most components were lifted through a roof hatch utilising an aluminium gantry and an electric hoist.
The expertise in pre-planning, logistics and practical know-how allowed for this challenging project to be completed in just three weeks. Alimak Service together with CoxGomyl coordinated transport of the equipment to the site, unloading and lifting into position, all the way through to installation. Every inch of the route was meticulously planned, taking into account the dimensions of every door and roof hatch opening, elevator sizes and weight capacities, all working in conjunction with a qualified and experienced rigger to ensure there was no damage to the building or the BMU components.

As an indispensable partner in the construction of a major city tunnel project, Alimak Service played a key role in ensuring the custom engineered vertical access solution from Alimak was efficiently installed.
This extensive public infrastructure work in Brisbane, Australia includes digging twin tunnels of 5.9 kilometres beneath the river and the Central Business District. Alimak were entrusted with designing and manufacturing a unique Alimak SC 65-32 hoist for access which was specifically engineered for the requirements of this tunnelling project.
The Alimak Service team, worked with together with Alimak’s project managers and engineers to overcome a range of challenges throughout every stage from initial consultation to installation.
Alimak Service brought with them unrivalled expertise which was invaluable in the completion of a complex installation, especially for a bespoke hoist unit.
The project called for a top to bottom vertical access solution for tunnel workers travelling 40 metres with two landings, all of which would need to operate in a remarkably limited space. The parameters also dictated that the mast would have to run along the wall, making twin door access to the hoist particularly difficult to achieve. An access platform was locally designed, fabricated and installed by the Alimak Service team to provide access for the Alimak hoist. The platform is temporarily installed for this rental project.
Alimak manufactured a SC 65-32 hoist which met these requirements with specialist fabrication, testing and certification completed in Melbourne. The hoist was then transported to Brisbane as an oversized load and lifted on to the site by crane for the Alimak Service team to undertake an equally unique installation. The extremely limited space available made installation challenging. Due to Alimak Service’s specific expertise and special working relationships with the leading names in the access industry, the on-site team were able to complete the complex installation of the unique
hoist successfully and within tight timelines.
The custom hoist and platform will now remain in place over a two-year rental arrangement, providing reliable and efficient access to workers throughout this major urban tunnelling project while also contributing to safer working practices.
On many sites around the world, vertical access equipment is key to the flow of profitable and efficient operations. Construction hoists, industrial elevators, building maintenance units and wind turbine service lifts all provide vital access during construction or for inspections and maintenance on critical facilities.
As the service provider for Alimak Group’s range of vertical access products, Alimak Service delivers a comprehensive range of service and support solutions designed to minimise downtime and extend the operational life of vertical access equipment. Alimak Service promotes regular servicing and maintenance to help owners and operators remain compliant with local and industry regulations and maintain high levels of safety at all times.
Here’s a guide to how often construction hoists, industrial elevators, building maintenance units and wind turbine service lifts should undergo preventative maintenance.
Alimak construction hoists and industrial elevators
To minimise the risk of inconvenient downtime, owners and operators of Alimak construction hoists and industrial elevators should ensure that scheduled maintenance work is carried out regularly and at the recommended time intervals in accordance with the manual of each model. It is also prudent to check local regulations which may vary from information recommended in equipment manuals.
Any adjustments or part replacements that take place as a result of inspections should be carried out by a skilled technician trained to service Alimak’s products. Additionally, only genuine Alimak spare parts should be used to ensure optimal system performance and preserve the validity of the warranty.
The Alimak Safety Device, gearbox, counter roller, switches, emergency stop mechanism, brake lining, brakes, life cables and electric motor should be inspected every 3 months or 40 operating hours to allow for necessary maintenance.
The rack and pinion, emergency lighting, emergency lowering, and enclosures should undergo inspections and or preventative maintenance every 120 operating hours or every 6 months.
Every year or every 1000 operating hours, inspections should take place for corrosion, damage and wear including the mast, guide rail, cable guides and control panels. The hydraulic systems should also be inspected and undergo maintenance or refurbishment if necessary.
As one of the most essential Alimak parts, the Alimak Safety Device should be completely replaced either four years from the first documented drop test on-site or after the date stamped on the device.
Manntech and CoxGomyl building maintenance units
Alimak Service provides a comprehensive range of service and support solutions for Manntech and CoxGomyl building maintenance units designed to optimise performance and support greater longevity for the equipment. Owners and operators of BMU systems should follow the guidelines from the original equipment manufacturer to preserve the safety and performance of the equipment.
Service intervals for BMUs are determined by the number of operating hours or time thresholds, usually whichever is reached first. Many standard BMUs should undergo servicing after 40 operating hours or 6 months depending on the frequency of cycles and the machine type.
Owners and operators of Manntech and CoxGomyl BMU systems should consult their local Alimak Service office to determine the required servicing schedule.
Owners should ensure that only genuine spare parts are used during any servicing work so as not to compromise the warranty of the equipment manufacturer. Depending on the condition of the equipment, additional maintenance work may also be required to replace or refurbish some components or systems.

The comprehensive service and support solutions provided by Alimak Service have played a key role in the construction of Landmark Pinnacle residential skyscraper in the heart of London’s Docklands. The 239-metre tower will become the tallest residential building in Europe and at 75 storeys, will also have more habitable floors than any other residential building on the continent. A construction project of this scale requires a range of appropriate vertical access solutions and the expertise and excellence in servicing to keep the vertical access equipment operating reliably and efficiently.
Four high-functioning Alimak construction hoists were purchased, with a fifth hired later in the project, all of which shared a common tower. This helped save space on an already congested ground floor podium area and along with a staggered hoist strategy, also helped to minimise costs and maximise efficiency. In conjunction with the 75 storey 5mtr x 5mtr Common Tower; the project included the supply of a high speed Alimak Scando 650 FCS XL (2mtr wide hoist) with a travel speed of 100m/min. Amongst the other passenger goods hoists supplied, was a large specialist twin mast TM Mammoth hoist with a capacity of 5,500kg and a volume of 45m³.
Two CoxGomyl building maintenance units (BMUs) mounted on a central twin track were also supplied for ongoing facade maintenance, facade cleaning and emergency glass replacement. These machines will be used by the client for routine cleaning and building maintenance requirements for many years to come.
The comprehensive package provided by Alimak Service initially began with the installation of the common tower and construction hoists. The Common Tower installation (which is normally installed by hand) was assisted on this project by the tower crane, with the construction hoists being erected in a sequence that maintained vertical access for personnel and material throughout the project with minimal downtime. The program required the installation to keep up with the concrete frame installation of constructing one floor per week.
Beyond the initial installation and training of operators, Alimak Service provided ongoing support to ensure optimal performance through a comprehensive Service package. This encompassed proactive project management and regular preventive maintenance visits on all of the products to ensure productivity was being maintained safely at the highest level.
The project benefited from a locally based service team and access to genuine spare parts for the quickest possible response and minimum downtime. Alimak Service also helped to facilitate the expanded use of the common tower to complete facade infill work to two thirds of the building, requiring tie removal and reinstallation sequencing to be executed whilst vertical material and personnel movements continued. The complete dismantle of the common tower and hoists was completed on time, on budget and safely.
Following the installation of the BMUs, Alimak Service completed extensive testing and certification. Alimak Service will also be providing peace of mind with ongoing protection of this investment in facade access with a service maintenance agreement. The BMU service package is completed with operator and duty holder training.
Alimak Service is uniquely qualified to deliver the best possible service for the leading brand names across the vertical access industry. This includes fast and convenient access to genuine Avanti parts for wind turbine service lifts, genuine spare parts for building maintenance units from Manntech and CoxGomyl and an extensive range of genuine spare parts, for a range of vertical access systems from Alimak from constructions hoists to industrial elevators.
