Classification of car lifts
At present, there are Foshan mountains (PEAK), Henan Italian Deli, JIG (Jinhua), Han McKesson, the order, China, Wan Li Kai AMREOC, Guangli, Gaochang, prosperous, large, Ao Fu , Bus, heavy vehicle-based) and so on. Production of the lift in the form of a wide range, from the column structure to classify, mainly single column lift, double column lift, four column lift, scissors lift and trench type elevator Wait.
Scissor lift part of the implementation of the use of shear-type pole, electric drive mechanical transmission structure, is currently widely used in large vehicle maintenance. Scissor lift is moderate and does not occupy the position of the car pit, for some models are relatively fixed, the intensity of work (such as in the bus) repair area is undoubtedly the best choice. And because the structure is simple, good synchronization, commonly used as a four-wheel locator platform.
Four-column car lift is a large tonnage car or truck repair and maintenance units commonly used special mechanical lifting equipment, four-column car lift is also suitable for four-wheel positioning, because the general four-column car lifts are There are four wheel positioning gears that can be adjusted to ensure the level. Four-column lift according to its structure is divided into two types of cylinder and under the cylinder. On the cylinder-type four-column lift the cylinder placed in the top of the column (with beams), the next cylinder-type cylinder placed under the plate. On the cylinder-type four-column lift mainly rely on four chains to pull up the four corners, pull the oil cylinder at the top, this structure is simple, but the weight increase. Most of the upper four-cylinder lift is lifted manually or pneumatically, and the mechanic needs to run underneath, which is inconvenient and unsafe for users who are often using secondary lifts. The safety device is a pneumatic device, if there is no gas is too much trouble. The four-column lift of the lower cylinder mainly relies on the four corrugations from the four corners. The tension cylinder is placed under the flat plate and the force is transmitted through the six discs. This structure is relatively compact, weight reduction. The second lift is generally electric hydraulic, and the main pump connected together, as long as the turn can change the valve,
Double-column car lift is a vehicle repair and maintenance units commonly used special mechanical lifting equipment, widely used in cars and other small car repair and maintenance. The double-column car lifts lift the car in the air while saving a lot of ground space for easy ground operations. But the double-column car lift for the largest saving material, generally removed the floor. Because there is no floor, so that the torque of the column need to rely on the ground to offset, so the ground is very demanding, if there are beams (gantry lift) to rely on beams offset.
A single-column lift is a special equipment for lifting a vehicle that is parked on the ground and lifted to a certain height. It is a typical local lift for cars and construction vehicles in order to replace wheel tires or Various equipment for the maintenance of the vehicle chassis. Single-column lift machine easy to operate, beautiful, do not take up space will be able to lift the weight of convenience. With the effect of saving time and effort, when not completely placed on the ground to facilitate the car reversing and placing items, car repair is an indispensable tool. Single-column vehicle lift is divided into two types: movable and fixed. Single column mobile lift is suitable for indoor and outdoor venues, single column fixed lift machine for indoor area is more compact place.
