According to the space occupied, it can be divided into above ground type and underground type;

The floor lift does not need to dig grooves, and is suitable for any repair shop. Some floors are not suitable for installing two-post lifts and ordinary four-post lifts, and the machine has a wide contact surface with the floor. Above the floor to solve the customer's venue problem. The biggest advantage of scissor lifts over two-post and four-post lifts is that they do not take up space and are easy to use. The disadvantages are that the charge balance is very strict, and it needs to be equipped with a control box, which is more expensive.

1. When the lift rises to the maximum lifting height, the limit switch will automatically power off and automatically cut off the hydraulic circuit in the hydraulic pump;

Installation description of two-column gantry lift 1: Place the main and auxiliary columns on the ground side by side, and install the beam, pay attention to tighten all screws 2: Wear the steel wire rope, tubing, limit line on the beam, so After the column is erected, do not climb to the upper area of the beam to install things. 3: On the side with 3 people, erect the column and adjust the position. 4: Measure with a spirit level and adjust the two columns not to tilt or twist. Then use a horizontal pipe to measure whether the column is on a horizontal surface.

5: The oil pump is connected, and the Great Wall 46 hydraulic oil is added.
6: Make sure that the oil cylinder chain and wire rope connection are in place. Jog and lift it to make sure that the voltage is positive and negative.
7: Lift a car, lift about 0.6 meters high, lock in the insurance position 8: Tighten the two steel ropes to the same

Four-post lift installation

1: Determine the installation place, the two flat beams should be flat with a height of about 0.5 meters 2: The two flat plates are placed on the beam and fixed 3: Put the four columns in place 4: Wear the wire rope 5: The columns and the block Leave a distance of 10mm. 6: Make a main column expansion screw 7: Lift the lifter and adjust the gap 8: All the expansion screws 9: Measure with a spirit level and adjust the four columns to not tilt or twist. Then use a horizontal tube to measure whether the plate is on a horizontal surface, and adjust if it is not possible

1. Before use, remove the appliances and sundries near the lift that hinder operation, and check whether the operating handle is normal.

Second, the operating mechanism is sensitive and effective, and the hydraulic system does not allow crawling.

3. When supporting a vehicle, the four supporting angles should be on the same plane. Adjust the height of the supporting angle rubber pad to contact the supporting part of the vehicle chassis.
