MONORAIL SYSTEMS FOR FACADE INSTALLATION & LIFTING

A monorail system for suspended access is an engineered track installed at roof or slab level that allows a cradle or platform to travel along a building façade. 

It provides continuous, controlled access for installation, inspection and maintenance works without the need for full scaffolding or mast climbers. Systems can be designed as temporary solutions for construction or permanent installations for ongoing façade maintenance.

Monorail cradles are suspended platforms connected to a travelling trolley running along a fixed track system. The cradle can move vertically as well as laterally, allowing operatives to access large areas quickly and efficiently without repositioning equipment. This enables a safer and more efficient method of working, particularly for glazing, cladding and façade finishing works.

A monorail cradle traverses along a lightweight aluminium track system suspended over the building edge. It is a simpler solution that can be deployed for targeted areas, or full building coverage, on a temporary or permanent basis.

A BMU (Building Maintenance Unit) is a more complex, permanent system—usually a powered machine with telescopic or luffing capabilities designed to access multiple façades from roof level. Monorails are often selected where a full BMU is not required or where a more cost-effective, project-specific solution is appropriate. 

As a market leader in both temporary and permanent access systems, Zarafa can support projects with either requirement. 

Monorail systems are used across a wide range of buildings, including high-rise residential developments, commercial offices, hotels and complex façade structures. They are particularly effective on buildings with long or repetitive elevations, recessed façades or restricted ground-level access where scaffolding or MEWPs are impractical.

Yes, monorail systems can be engineered to support both suspended access platforms and lifting equipment. This allows materials such as glazing panels, cladding units and façade components to be transported directly to the point of installation, improving efficiency and reducing reliance on cranes.

Monorail systems provide continuous façade access, reduce the need for scaffolding and improve overall site efficiency. Key benefits include:

• Reduced programme durations 

• Improved material handling 

• Safer, engineered access 

• Reduced crane dependency 

• Minimal disruption to other trades 

They are particularly effective on high-rise and complex façade projects.

Yes. By enabling materials to be moved vertically as well as horizontally along the façade, monorail systems can significantly reduce the need for crane lifts. This not only improves programme efficiency but also reduces costs and site congestion.

Yes, monorail systems are well suited to live construction environments. They can be installed in phases and operated with minimal disruption to ongoing works, making them ideal for busy or constrained sites.

Monorail systems are typically used where continuous façade access is required without the cost, time and visual impact of scaffolding. 

They are particularly effective on high-rise or complex buildings, allowing operatives to move efficiently along elevations while reducing programme duration and crane dependency.

Monorail systems are designed on a project-specific basis, considering building geometry, structural capacity, loading requirements and intended use. 

This includes detailed engineering calculations, track layout design and coordination with the building structure to ensure a safe and practical solution. 

At Zarafa, systems are engineered to suit the specific façade geometry and loading requirements by our in-house design and engineering team.

Load capacity depends on the system design but typically includes personnel, tools and façade materials. Systems are engineered by Zarafa to meet project-specific requirements with appropriate safety factors, ensuring compliance with relevant standards.

Yes, monorail systems can be designed to follow complex geometries, including curved or stepped façades. Bespoke track layouts allow access to challenging building forms that would be difficult to reach using traditional methods.

Monorail systems must comply with relevant UK legislation and standards, including the Work at Height Regulations, LOLER (Lifting Operations and Lifting Equipment Regulations 1998),BS EN 1808:2019 Safety requirements for suspended access equipment. Design calculations, stability criteria, construction. Examinations and tests and BS 5974:2017 Planning, design, setting up and use of temporary suspended access equipment. Code of practice. 

Design and installation are also carried out in line with recognised engineering and safety standards.

Yes, structural verification is essential to confirm that the building or supporting structure can safely accommodate the imposed loads. 

This forms a key part of the design and engineering process, which Zarafa can offer further support.

Yes, temporary monorail systems can often be installed on existing structures, subject to detailed assessment and verification of load capacity and fixing arrangements. Visit our case studies to see examples of this.

Installation typically involves fixing the track system to the building structure, installing trolleys and rigging a suspended platform consisting of man riding hoists and safety devices, and completing thorough testing and commissioning. Systems are then certified prior to use. The same process applies to lifting gear monorails, which can be added alongside the cradle track to provide a more enhanced solution for façade related works.

Yes, temporary monorail systems can often be relocated or adapted as the project progresses, providing flexibility as façade works advance. Zarafa have installed systems that are relocated up the building as cladding or façade works are performed. See Case Study of a hotel in Manchester.

Monorail systems require regular inspection and maintenance to ensure safe operation. 

This typically includes routine checks and statutory inspections in accordance with LOLER and manufacturer guidance. Zarafa teams can support this, including factory based testing of equipment by manufacturer approved engineers.

Yes, Zarafa provides a fully engineered, turnkey service including design, installation, testing, inspection and certification—ensuring compliance and continuity throughout the project lifecycle. Contact us for further information.

Monorail systems can be provided on a hire basis for temporary construction projects or as permanent installations, depending on project requirements.

Yes, monorail systems are widely used for curtain wall installation or removal, providing safe, efficient access and enabling materials to be positioned accurately at the point of installation.

Yes, monorail systems are particularly effective for high-rise façade works, offering continuous access, improved safety and enhanced productivity.

Yes, lifting monorails can be engineered to handle glazing panels, cladding units and other façade materials, supporting efficient and controlled installation processes.

Yes. In addition to monorail systems, Zarafa provides a comprehensive range of engineered façade access and height safety solutions. 

This includes permanent systems such as BMUs (Building Maintenance Units), gantries, davits and fall protection systems, alongside temporary solutions including suspended cradles, hoists and bespoke lifting arrangements for construction projects.

Our engineering-led approach enables us to design, supply, install and maintain fully integrated solutions tailored to each building. This ensures a coordinated access strategy across both construction and long-term maintenance, rather than standalone systems.

Zarafa is solutions-focused, with all services underpinned by strong engineering capability, competency and compliance. Supported by both factory-based and mobile engineers, we ensure systems are not only delivered effectively but continue to operate safely and reliably throughout their lifecycle.
