Challenge
Structural Leverage & Kinematic Interlocking in the Track Mounted Scissor Lift Platform
A major mechanical risk with a long, thin platform layout is the dynamic Scissor Arm Deflection that occurs under off-center loading. When operators stand on the extended 1-meter cantilever section, the gravity load generates a leverage moment . To counter this, the Electro Hydraulic Scissor Table scissor legs are constructed from thick-walled 2001008mm rectangular steel tubes rather than standard plate steel . Furthermore, the high-stress pivot points are equipped with a massive Ø90 mm Heavy Duty Pivot Pin layout . To guarantee absolute safety, an S7-1200 PLC-controlled Interlocking Safety Circuit ensures that the horizontal drive cannot activate while the scissor arms are lifting, and the telescopic deck cannot extend unless the outrigger mechanism is fully deployed.
Each 1-meter extendable deck section is driven by a heavy-duty Electric Push Rod Actuator working along high-rigidity linear guide rails. This allows inching control and locking at any intermediate position . While traveling horizontally at 2 m/min, an Audio Visual Run Alarm warns nearby personnel . To ensure safe boarding, a built-in foot pedal is welded to the lower structure . If a hydraulic conduit ruptures, redundant hose burst safety valves on the twin Ø90-70 hydraulic cylinders instantly seal the oil, preventing any uncontrolled descent of the Track Mounted Scissor Lift Platform
Solution
Detailed Engineering of the Track Mounted Scissor Lift Platform
The structural frame of the Track Mounted Scissor Lift Platform is welded from 16# high-tensile channel steel to resist bending forces under asymmetrical loads . The lift utilizes two independent single-scissor groups arranged in a 1-layer, 2-span configuration under the 5-meter platform . Power is delivered by a 4 kW HPU consisting of a Beijing Huade valve block, a Jinan Military pump, and an energy efficient Inmenda motor . This custom Electro Hydraulic Scissor Table ensures steady lifting and lowering speeds of 2-3 m/min
To manage multi-axis operations, the Siemens S7 PLC regulates all automated and manual inputs The Telescopic Deck Scissor Lift uses continuous guardrails (1.1 m high) integrated with secure door locks . On top of the guardrails, continuous overhead hoist points allow workers to attach safety harnesses easily while moving across the platform . The control panel includes a phase-failure protection relay and a comprehensive Interlocking Safety Circuit that stops all translation if the entry gate is left open .
To handle horizontal mobility, the bottom chassis is mounted on a P22 Rail Guided Carriage drive . The travel drive consists of heavy steel wheels matching the rail profile, driven by a braked gearmotor to prevent drift when stationary . The dual-motor drive ensures exact synchronization along the 8-meter track . By combining vertical lifting with stable horizontal travel, the Track Mounted Scissor Lift Platform solves complex installation tasks without requiring multiple single-purpose scissor platforms .
Every single dynamic stress test of the Track Mounted Scissor Lift Platform conforms to modern heavy B2B application demands.
When designing the lift, our engineers limited Scissor Arm Deflection to under 1.5% of the total extended length. Each high-tensile joint relies on a custom-ground Heavy Duty Pivot Pin. To extend the workspace, the dual Electric Push Rod Actuator modules extend smoothly, backed by reliable proximity limit switches . When in motion, the high-intensity Audio Visual Run Alarm keeps the factory floor compliant with safety standards .
