The trailer boom lift aerial work platform is modified from a cargo lift platform and a car. It takes the power of the car engine and realizes the lifting function of the lifting platform. PickH-type hydraulic outriggers are used to ensure the stability of the machine’s lifting and operating safety. DC independent power source can be used to realize the rotation and lifting functions of the elevator. Suitable for high-altitude operations with a wide working area and a large range. The product has the characteristics of a large operating range and long continuous operation time. It is especially suitable for field maintenance, street lamp maintenance, and tree pruning.
The battery-mounted aerial work platform is a piece of special equipment for aerial work that is converted from a lifting platform and a battery car. It utilizes the original DC power of the battery car and can realize the lifting of the lifting platform and the movement of the whole machine without an external power supply. It is easy to move, has a wide range of operating flow, the product has no pollution, no tail gas, large operating range, and strong fluidity. Especially suitable for cold storage, crowded areas train stations, bus stations, airports.There is a diesel engine with telescopic boom, can overhang operation, cross certain obstacles or lift in one place for multi-point operations; 360-degree rotation, large load capacity of the platform, can accommodate two people or Many people can work at the same time and can carry certain equipment; the lifting platform has good mobility and convenient transfer site; beautiful appearance, suitable for indoor and outdoor operations and storage. It is suitable for large-scale operations such as stations, docks, shopping malls, stadiums, residential properties, factories, and mines.
The crank-type aerial work platform is called the aerial work platform truck, which is mainly used in a relatively high working environment, carrying between one to two people. The fire brigade generally uses this type of elevator.The hydraulic oil forms a certain pressure by the vane pump and enters the lower end of the cylinder through the oil filter, explosion-proof electromagnetic directional valve, throttle valve, hydraulic control one-way valve, and balance valve so that the piston of the cylinder moves upwards and lifts the weight. The hydraulic oil at the upper end of the cylinder is returned to the tank through the explosion-proof electromagnetic directional valve, and its rated pressure is adjusted through the overflow valve, and the reading of the pressure gauge is observed.The piston of the hydraulic cylinder moves downward that is, the weight drops.
The hydraulic oil enters the upper end of the cylinder through the explosion-proof electromagnetic reversing valve, and the return oil from the lower end of the 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 hydraulic control check valve, namely a hydraulic lock, is added to ensure that it can lock itself safely when the hydraulic pipeline bursts accidentally. An overload sound-activated alarm is installed to distinguish overload or equipment failure.
