The production of lift in the form of a wide variety, from the column structure to classify, mainly single column lift, double column lift, four column lift, shear lift and trench lift.

A, single column lifting machine

Single-column lift is a special equipment that lifts vehicles such as cars parked on the ground to a certain height for maintenance, and is a typical tool used for local lifting of automobiles and engineering vehicles in order to replace wheel tires or carry out various maintenance operations on the vehicle chassis. The single column lift is easy to operate, beautiful, and can lift heavy objects conveniently and effortlessly without taking up space. It has the effect of saving time and labor, completely placed on the ground when not in use, convenient for car reversing and placing items, and is an indispensable tool for car repair. The single column vehicle lift is divided into two types: mobile and fixed. The single-column mobile elevator is suitable for indoor and outdoor venues, and the single-column fixed elevator is suitable for places with relatively compact indoor area.

Two, double column lifting machine

The double-column automobile lift is a special mechanical lifting equipment commonly used in automobile repair and maintenance units, which is widely used in the repair and maintenance of small cars such as cars. The double column car lift can save a lot of ground space while lifting the car in the air, which is convenient for ground operation. However, in order to save more materials, the bottom plate is generally removed. Because there is no bottom plate, the torque of the column needs to be offset by the ground, so the foundation is very demanding, if there is a beam (gantry elevator), it is offset by the beam.

There are two kinds of double column lift: symmetrical and asymmetric. The arm length of the four arms of the symmetrical lift is roughly equal, so that the center of the car (or center of mass) is in the middle of the column, and this symmetrical lift may be a better choice for daily maintenance of vehicles such as pickup trucks and box trucks. However, for some symmetrical double-column lifts whose width between columns is not large enough, it is a big disadvantage that the car cannot open the door after lifting. The column of the asymmetric lift is rotated back at an Angle (about 30°), and the forearm is slightly shorter than the rear arm. When the car is parked in the proper position of this asymmetric lift, the position of the car is moved backwards, so that we can easily enter and exit through the door. Moreover, this asymmetric lift rotates the columns to ensure that the center of gravity of the vehicle is securely positioned between the columns.

Three, four column elevator

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 very suitable for four-wheel positioning, because the general four-column car lift has a four-wheel positioning gear, can be adjusted to ensure the level. According to its structure, the four-column lift is divided into upper cylinder type and lower cylinder type. The oil cylinder of the upper cylinder type four-column lift is placed on top of the column (with a cross beam), and the oil cylinder of the lower cylinder type is placed under the plate. The cylinder type four-column lift machine mainly relies on four chains to pull up four corners, and the tension cylinder is placed on the top, which is simple in structure, but the weight increases. The secondary lifting of most upper cylinder four-column lifts is manual or pneumatic, and the repairman needs to run to the bottom of the operation, which is inconvenient and unsafe for users who often use secondary lifting. The safety device is a pneumatic device, if there is no air source, it is more troublesome. The lower cylinder four-column lift mainly relies on four thick steel cables to raise the four corners, and the tension cylinder is placed under the plate, and the force is transmitted to the four sides through six disks. This structure is relatively compact, and its self-weight is reduced. The secondary lifting is generally electro-hydraulic, and the main pump is connected together, as long as the rotation of the transfer valve can be, the lifting speed is fast, the safety device is a wedge type, the four wedge blocks use the pull rod linkage, the pull rod can open the safety device, convenient and durable.

Four, shear lift machine

The shear lift adopts the form of shear stack rod and the electric drive mechanical transmission structure, which is widely used in the maintenance of large vehicles. The lifting speed of the shear lift is moderate and does not occupy the pit position, and it is undoubtedly a better choice for some models with relatively fixed work intensity (such as in the bus) in the field of repair. And because of its simple structure and good synchronization, it is generally used as a platform for four-wheel locator.

Shear lift machine is divided into several types, such as large shear (child and mother), small shear (single shear), ultra-thin series shear lift machine. Small shear lift machine is mainly used for automobile maintenance, high safety, easy to operate. Level with the ground after digging. The large shear lift gushed out more, which is better equipment with the four-wheel positioning instrument, and can be used for car maintenance, tire, chassis maintenance. It can be dug or installed directly on the ground. Ultra-thin series shear lift without digging, suitable for any repair shop, there are some floors are not suitable for the installation of two-column lift and ordinary four-column lift, and the machine and the floor contact area is wide, so that it can be installed in any can drive the floor above, to solve the customer site problem. This kind of machine is the mainstream product in the future, and this kind of product is used on a large scale abroad.

Five, trench elevator

Gutter lift is the ideal equipment for large bus maintenance, it is more practical for the workshop with low space, and it is cheap. Gutter type car elevator, installed in the gutter above the two sides of the track, generally using electric drive mode, worm, worm gear deceleration, thereby driving the screw, lifting girder lift. This design method makes the gutter lift move more flexible, lifting force is greater, the lifting is smooth, the operation and installation is very convenient, is the most ideal lifting equipment for all kinds of bus, truck maintenance enterprises. The position of the front wheel corner plate (optional) of the gutter racetrack type four-wheel positioning elevator is adjustable, and the rear wheel skateboard is extended, which is suitable for positioning measurement of various models.
