4 Post Car Lift Machine Hydraulic Car Lift

4 Post Car Lift

Four-Post Lifts is a special mechanical lifting equipment commonly used by the repair and maintenance units of large tonnage cars or trucks. 4 Post Electric Car Lift Elevator is also suitable for four-wheel positioning, because the general four pillar Car Lift has a four-wheel positioning gear, which can be adjusted to ensure the level.

According to its structure, four column lifting machine can be divided into two types: upper cylinder type and lower cylinder type. The oil cylinder of the upper oil cylinder type four column lift is placed on the top of the column (with a beam), and the oil cylinder of the lower oil cylinder type is placed under the plate. The upper cylinder type four column lifting machine mainly relies on four chains to pull up four corners, and the tension cylinder is placed on the top. This structure is simple, but the self weight is increased. Most of the secondary lifting of the upper cylinder type four column lifting machine is manual or pneumatic, and the repairman needs to run down to operate, which is inconvenient and unsafe for the user who often uses the secondary lifting. The safety device is a pneumatic device, which is troublesome if there is no air source. The four column lifting machine of the lower oil cylinder mainly relies on four thick steel cables to pull up the four corners. The tension oil cylinder is placed under the plate and the force is transmitted to all sides through six discs. The structure is compact and the weight is reduced. The secondary lifting is generally electro-hydraulic and connected with the main pump. As long as the change-over valve is turned, the lifting speed is fast. The safety device is wedge type. The four wedges are linked by the pull rod, and the safety device can be opened by pulling the pull rod, which is convenient and durable.

Four post lifting machine is a lifting device frequently used in automobile repair and maintenance. Compared with other devices, this device has the following technical advantages:

1. The hydraulic system of the four column hydraulic lift adopts a quantitative hydraulic pump oil source, which is conducive to reducing energy consumption and system heating;

2. The synchronous hydraulic cylinder is controlled by the diverter and collector valve, which can basically meet the synchronous requirements of the hydraulic cylinder;

3. The two-stage hydraulic control one-way valve is used to realize the locking and lifting stop of the hydraulic cylinder after lifting;

4. Hydraulic power lifting device can reduce noise and achieve lifting stability;

5. The wire rope stable system is adopted to avoid tilting of the vehicle during lifting. In addition, the four column hydraulic lift can transmit power when the center distance between the two shafts is far, which can ensure accurate transmission ratio, large transmission power and transmission.
