Working Principle
The hydraulic oil in the SJY mobile lift platform is pressurized by a vane pump, then passes through the oil filter, solenoid directional valve, throttle valve, pilot-operated check valve, and counterbalance valve before entering the lower end of the cylinder, forcing the piston upward to raise the load. During lowering, the hydraulic oil flows through the directional valve into the upper end of the cylinder, while the oil from the lower end returns to the tank via the counterbalance valve, check valve, throttle valve, and directional valve. The counterbalance valve in the return line maintains pressure to keep the hoisting speed independent of the load, the throttle valve regulates the hoisting speed, and the hydraulic lock valve ensures safe self-locking in the event of an unexpected hose rupture.

FAQ
What national standards does the SJY mobile lift platform comply with?
A: The design & manufacturing follows GB/T 25849 "Mobile Elevating Work Platforms," the scissor structure meets JB/T 9229 "Scissor Lift Platforms," and electrical safety complies with the relevant clauses of GB 5226.1 "Electrical Safety of Machinery."
What is the difference between the SJY mobile lift platform and a fixed lifting platform?
A: The SJY is a mobile unit equipped with a four-wheel towable chassis that can be manually moved to different work locations, making it ideal for high-altitude tasks across multiple areas. A fixed lifting platform is installed at a specific location and is better suited for frequent lifting at a single workstation.
What is the price range for different SJY mobile lift platform models?
A: 6m models are approximately RMB 8,000~15,000; 9~12m models range from RMB 18,000~35,000; 14~16m models are priced at RMB 38,000~80,000. Custom non-standard manufacturing is quoted separately, and tax-inclusive pricing with freight needs to be confirmed.
