How does the crank construction lift platform work? Here are the staff of Guoqi electric lifting platform manufacturers to introduce to customers and friends 1. The lifting capacity of the pressure jack has reached 750 tons. The crank arm type lifting cage platform is mainly used for vertical or nearly vertical lifting movement, and has a fixed lifting cage route, including elevators, lifting platforms, mine hoists and hopper lifting platforms. A crane is a multi-action hoisting machine that vertically lifts and transports heavy objects horizontally within a certain range. The overhead monorail system has a line formed by rigid hanging rails, which can transport materials to various parts of the plant, and can also be extended to the outside of the plant. 2. The hydraulic oil of the crank arm type lifting platform is formed by the vane pump to a certain pressure, and enters the lower end of the hydraulic cylinder through the oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control check valve, and balance valve. The piston moves upward to lift the weight. The oil return from the upper end of the cylinder is returned to the fuel tank through the flameproof electromagnetic reversing valve. The rated pressure is adjusted through the overflow valve, and the pressure gauge reading value is observed through the pressure gauge. 3. The piston of the hydraulic cylinder moves downward (that is, the weight drops). The hydraulic oil enters the upper end of the hydraulic cylinder through the explosion-proof electromagnetic reversing valve, and the return oil at the lower end of the hydraulic cylinder returns to the tank through the balance valve, hydraulic control check valve, throttle valve, and explosion-proof electromagnetic reversing valve. In order to make the heavy objects fall smoothly and brake safely and reliably, a balance valve is installed on the oil return line to balance the circuit and maintain the pressure so that the descending speed is not changed by the weight. The throttle valve adjusts the flow rate and controls the lifting speed. In order to make the brake safe and reliable, and prevent accidents, a hydraulically controlled one-way valve, that is, hydraulic lock, is added to ensure that it can be safely self-locked when the hydraulic pipeline bursts accidentally. An overload sound-activated alarm is installed to distinguish overload or equipment failure.
