Boom lift platform is lifting equipment for high-altitude operations, can overcome obstacles when aerial work platform lift to any location, can walk side side jobs, compact, flexible steering, the width of its sites can ensure that equipment into the narrow channel and crowded work area. Standby power means operable working platform reset and convenient mode of transport that can be drawn to any place. Easy to identify the control panel, multiple mechanical, electrical and hydraulic safety protection, advanced integrated hydraulic system electrical integration. Category: Boom Lift are: self-propelled diesel, trailer, NRK, battery, vehicle-mounted. Purpose: crank aerial vehicles are widely used in municipal, electricity, street lighting, advertising, communications, photography, gardening, transportation, terminals, airports, ports, large industrial and mining industries and climbing installation and maintenance operations. For the wild variety of rugged terrain, a wide range of space operations, mainly used in construction, bridge construction, shipbuilding and construction, airports, mines, ports, telecommunications and power facilities and outdoor advertising engineering machinery and equipment. Diesel Boom Lift: no external power supply, erection suitable for field work at height, walking and diesel powered lift, big power, walking speed. Trailer Boom Lift: can be hung on the car, synchronized with the car, suitable for field-altitude operations. Lift: 1, 2 with 380-220V power supply, power supply is not convenient, you can use the battery-driven lift. Good looks, easy to walk. Car Boom Lift: The Boom Lift installed in the car, the use of power-driven car lift. Field far away for high altitude operations. Features: (1) the new self-propelled hydraulic special chassis. Developed with independent intellectual property rights of self-propelled aerial work platforms lift truck, using a hydraulic integration, reliability, design and computer-aided design technology, successfully developed a full hydraulic drive, self-propelled special chassis, breaking past domestic aerial work platform lift trucks can only use restrictions on vehicle or crane chassis modified design. (2) with load driving, good job stability. Chassis structure breaks the traditional design theory and methods, on the train platform by optimizing the overall layout and load distribution, reducing the center of gravity shifted. The unique wide-angle hinge point backwards type structure, a reasonable set of multiple counterweight module, effectively balance work torque. Using H-type variable cross cut of composite box beam frame and high load solid rubber tires, increasing the overall stiffness of the chassis, ensure the machine running, the stability of the job process, to achieve the aerial work platform lift trucks with load driving capabilities. (3) multi-function, multi-purpose operating system. Through the front bracket arm, lifting devices can be quickly installed or manned platform, material lifting, lifting and manned aerial work and other functions, as well as an extended job fast switching devices and various working device provides the interface . (4) a unique three-dimensional rotation lifts devices. Three-dimensional rotation lifts device designed to automatically keep both gesture by lifting materials, but can be adjusted to any height requirements for lifting material in the space, anywhere and in any direction, speed, precise control sensitive, fretting performance, meet the large cave on aerial work and ventilation pipe installation requirements. How it works: vane pump hydraulic oil is formed by a certain pressure, the oil filter, explosion-proof solenoid valve, throttle valve, check valve, balance valve into the lower end of the cylinder, so that the hydraulic cylinder piston moves upward , heavy lifting, the upper end of the hydraulic cylinder return oil through flameproof solenoid valve to the tank, which is adjusted by the rated pressure relief valve, pressure gauge readings by observing the pressure gauge. Hydraulic cylinder piston downward movement (both heavy fall). Explosion-proof hydraulic oil through solenoid valve into the upper end of the hydraulic cylinder, hydraulic cylinder through the lower back to the oil balance valve, check valve, throttle, explosion-proof solenoid valve to the tank. In order to decrease the weight stable, safe and reliable braking, set the balancing valve, balancing loop back to the oil on the road, keep up the pressure, so that the rate of decline from the weight change, the throttle valve regulates the flow, speed control movements. In order to secure the brake to prevent accidents and increase check valve, namely hydraulic lock, ensure that when an unexpected burst hydraulic lines can safely self-locking. Installed voice alarm overload, overload or equipment failure to distinguish.
