Retractable crane loading platform
Product Purpose: Indoor-outdoor material connection point, forklift operation ramp, heavy cargo up-and-down transfer hub.
Application Scenarios: Transition areas between podium and main tower construction, indoor material distribution channels, and heavy-duty equipment lifting floors.
Material & Craftsmanship: Main beams are typically 16# I-beams or channel steels, secondary beams use 5# channel steels, topped with 52 mm thick patterned steel plates or grating for high load-bearing capacity and anti-slip performance. Nodes are reinforced with full welding, featuring full and uniform weld seams; guardrails and toe boards are fully welded to eliminate loosening hazards.
Retractable Crane Loading Platform for High-Rise Construction: Freely Retractable Main Beams for Heavy Material Transfer
Hebei Xinjiuyi Construction Technology Co., Ltd. produces steel unloading platforms for high-rise construction sites. Our retractable crane loading platform is designed with major beams that can be easily retracted from the edge of the floor to accept cargo from the tower crane and then pulled back after the lift. It is steel with completely welded guardrails and toe boards. Length is 6000, 7000, 8000 or 9000 mm with a bucket length of 3000 mm, and weight varies from 370 kg to 720 kg. various sizes may be made to suit various levels, loads and site layouts.
How the Retractable Main Beams Work
The main beams move out to loading position and retract after the lift. This provides a specified transition point between the crane hook and the structure.
The platform serves as a linker of indoor-outdoor materials. The ramp may also be used as a forklift and a hub for the up and down transport of large material. Several cross sectional profiles are available, allowing you to fit the beam to your load and structure.
Where the Platform Is Used?
Safe handover point for materials required for transition zones of podium and main tower. The same goes for indoor material delivery lines and heavy-duty equipment lifting floors.
The retractable crane loading platform is suitable for vertical material handling in high-rise structures, temporary material storage on multiple levels, and tower crane lifting operations. Please check your local construction safety standards and the requirements of your project before usage and let us know in advance if you need particular documents.
Materials and Construction
Main frame is steel frame. Main beams are 16# I-beams or channel steels, while subsidiary beams are 5# channel steels.
The deck is patterned steel plate or grating, 52 mm thick and has an anti-slip surface. Full welding strengthens nodes. Guardrails and toe boards are entirely welded also.
Lifting rings are bent to provide easy passage of steel wire ropes. The surface is coated with rust-proof anti-corrosion coating and high-visibility yellow and black warning paint.

Safety Features for High-Altitude Work
The product incorporates a three-sided protection rail and anti-slip base plate surrounding the cargo. Small things are kept from rolling over the edge by toe boards.
These characteristics serve to limit the danger of falls from height and of items spilling over. The work zone is clearly marked with yellow-black paint, which also assists with site safety inspections.
Modular Installation and Reuse
Modular design permits installation and removal as the project progresses. You may then utilise the platform again on subsequent levels or on other projects.
Anchoring using through-wall tie rods with backing plates or with telescopic jack systems between floor slabs. Installation time varies with access to location and anchoring technique.
Customization and Project Support
Total length and height might be customised according to your designs, specification and application circumstances. Xinjiuyi also produces operating platforms in unusual shapes and customised protective canopies.
Project support includes product design support, solution design, manufacturing and supply, on-site installation advice, technology support and after-sales service.

FAQ
Q: Is the platform usable in windy conditions?
A: Wind may impact crane hoisting, causing loads to swing. Follow the wind restrictions in your site safety plan and crane operating guidelines and cease loading when the situation exceeds those limits.
Q: How fast can platforms be erected or relocated?
A: Time depends on how the anchors are set and access to the site. The platform may be raised as the work goes since it’s modular. Tell us about the situation at your location and we may assist you on your case.
Q: What maintenance has to be done?
A: Check welds, lifting rings and connection points before use as per your site inspection plan. Periodic inspections should be documented by qualified persons.
Q: How is the platform fixed to the building structure?
A: We employ mostly through wall tie rods with backing plates. Where penetrations are not possible, telescopic jack systems are braced in between floor slabs. The approach relies on slab thickness, edge reinforcement and architectural constraints.
Q: How can an enclosure design increase safety in material transport?
A: The three-sided guardrail and anti-slip base plate prevent goods from slipping or tumbling over the sides during hoisting.
Q: Is the product customisable?
A: Yeah. Adjustable total length and height. Send us your drawings and load requirements for a suitable solution.
