Hydraulic lifting platform is divided into fixed hydraulic lifting platform, scissors hydraulic lifting platform, mobile hydraulic lifting platform, aluminum alloy hydraulic lifting platform and boarding bridge hydraulic lifting platform.
1. The whole machine has light weight and good maneuverability, which is suitable for single operation.
2. Specially designed guide wheel device between mast pillars can lift smoothly and freely.
3. Compact structure, small size of transportation state, can enter the car of general elevator and can smoothly pass through the door and narrow passage;
4. The double protection leg structure can work safely and close to the lifting operation of the working face.
Double-column aluminium alloy elevator
Double-column aluminium alloy elevator is a new generation of products with new design. The whole product is refined with high strength aluminium profile, which makes the deflection and swing of the elevator very small. The double mast structure is adopted with large load, large platform area, excellent stability, flexible operation and convenient implementation. It has a lightweight appearance and can perform the highest lifting ability in the smallest space. The lift is widely used in factories, hotels, buildings, shopping malls, stations, airports, stadiums and so on. It can be used for the installation and maintenance of power lines, lighting appliances, elevated pipelines and other single-person work at high altitude.
Hydraulic oil forms a certain pressure by vane pump. It enters the lower end of the cylinder through oil filter, flameproof electromagnetic reversing valve, throttle valve, hydraulic control one-way valve and balance valve, so that the piston of the cylinder moves upward, lifts heavy objects, and the upper end of the cylinder returns to the tank through flameproof electromagnetic reversing valve. Its rated pressure is adjusted by relief valve. Observe the pressure gauge reading value through the pressure gauge.
The piston of the cylinder moves downward (as the weight drops). The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the oil returns to the tank through the balance valve, the hydraulic control one-way valve, the throttle valve and the explosion-proof electromagnetic reversing valve. In order to make the weight drop smoothly and brake safely and reliably, a balance valve is set on the return road to balance the circuit and maintain the pressure, so that the descending speed is not changed by the weight. The throttle valve regulates the flow rate and controls the ascending and descending speed. In order to make the brake safe and reliable and prevent accidents, a hydraulic control one-way valve, i.e. hydraulic lock, is added to ensure the safety of self-locking when the hydraulic pipeline bursts unexpectedly. An overload sound alarm is installed to distinguish overload from equipment failure.
Electrical control system controls the rotation of motor by explosion-proof button SB1-SB6, and the reversal of explosion-proof electromagnetic reversing valve, so as to maintain the load rising or falling, and adjust the time delay by program, so as to avoid the frequent start of motor and affect the service life.
