The Retractable Loading Platform

Climbing System

The Retractable Loading Platform is a telescopic material-handling platform designed for multi-storey and high-rise construction projects. Used in conjunction with tower cranes, it enables safe and efficient transfer of construction materials, equipment, tools and site waste to designated floors or ground-level transfer areas. With high load capacity, excellent stability, generally no requirement for embedded parts, and broad dimensional coverage, it is suitable for façade installation, ALC wall panel handling, steel structure lifting, large MEP equipment transfer, precast component handling, formwork material logistics and interior finishing material transportation.

The Retractable Loading Platform

ADVANTAGES

High Load Capacity and Wide Applicability
Available in light-duty 2.5-tonne and heavy-duty 5.0-tonne configurations, the platform meets diverse lifting and material-handling requirements across different construction stages.

Retractable Structure for Improved Site Efficiency
The sliding frame extends for floor-level loading operations and retracts to reduce cantilevered space occupation, enabling simultaneous use across multiple floors and positions.

No Embedded Parts Required
Supported by a reliable vertical propping system, the platform typically eliminates the need for U-shaped embedded bars, lifting rings and other cast-in components on each floor, reducing installation complexity and construction time.

Foldable Design for Lower Transportation Costs
The side panels can be folded during transportation, allowing easier loading, stacking and turnover, which improves logistics efficiency and reduces transportation costs.

Comprehensive Safety Protection
The platform is equipped with foldable guardrails, an external safety gate, anti-slip deck plates and an overload alarm system. When the carried load exceeds the rated capacity, the system provides an alarm to enhance on-site operational safety.

Customisable Dimensions and Load Capacity
Platform width, extension length, cantilever length and rated load capacity can be customised according to project requirements, making the system adaptable to different structures, site layouts and lifting tasks.

Suitable for Multiple Construction Applications
The platform is suitable for façade works, ALC wall panel installation, steel structure handling, large MEP equipment transfer, steel scaffold logistics, precast component lifting, concrete block handling, formwork material transfer and finishing material transportation.
