1. Difference between Clear Floor vs. Floor Plate Two-Post Car Lift
Clear floor two-post car lift is the oil pipe and wire rope are erected on the upper end of the columns, the ground between the columns is flat, and there is no obstruction in the vehicle passing area. Normal clear floor two-post car lift is a one-piece post, inverted cylinder, with roof crash limit on the crossbeam, suitable for car body not higher than 1600mm models.
Floor plate 2 post lift is oil pipe, wire rope in the ground between the two columns through, so the vehicle through the area of the block, because there is no restriction on the top, so there is no restriction on the height of the car. The maximum lifting height depends on the effective stroke of the cylinder and the height of the ceiling!

- lift up the lifting head, stuck in the same level of insurance position.
- the low position of the wire rope installation connection, note: The wire rope should go to the inside of the lifting head.
- the high position of the wire rope installation connection. Wire rope from the head down to wear up, wear out the head opening will be two wire rope nut interlocking.
- installation of a hydraulic station and oil pipe. Hydraulic station screws first lock lift to the power column fixed slot locking screws, three-way valve and two-way valve to find out the oil pipe connected to the synchronization of the other side of the oil pipe connected to the cylinder and the hydraulic station above.
- installation of protective wire groove: Oil pipe installation: Both sides of the oil pipe installation schematic. (note: Oil pipe and small wire rope can not cross).
- safety mechanism wire rope, oil pipe, and the installation of the protection line groove. The protection line groove above the outer column is fixed with m6*35 half-round head screws, and the protection line groove above the inner column is fixed with m6*40 half-round head screws. After all the above precautions are ok, you can install the protection wire channel. Will be covered by the slot in the column in order to use the cross flat head screws can be twisted tightly.
- installed lifting arm; lifting head down to the lowest position, at this time with 8 # hexagonal wrench to loosen the fixed gear hexagonal screws, according to the direction of the arrow can be adjusted gear, until the gear and rack to achieve a good state of mesh and lock the screws, with 8 # hexagonal wrench to loosen the fixed gear hexagonal screws.
- adjust the gear and rack meshing, gear and rack to achieve a good state of mesh with the hexagonal wrench to lock the screws.
- tighten all the oil pipe joints, to the hydraulic station full of hydraulic oil (in order to ensure the service life of the hydraulic system and to ensure that the equipment operates to the best state, please fill 46 high-quality anti-wear hydraulic oil).

19. Equipment debugging
(1) Adjustment of synchronized wire rope
Use an open-end wrench to hold the wire rope connector, and use a plum wrench to tighten the wire rope nut until the two synchronized wire ropes are adjusted to a certain tension and consistency. If the lifter does not run synchronously on both sides of the lifting head when it rises/falls, tighten the wire rope nut on the lower side of the lifting head until the lifter rises/falls in synchronized operation.
(2) Adjustment of safety mechanism wire rope
The two lifting heads will be lifted and stuck on the insurance, tighten the wire rope of the safety mechanism with force and then relax it a little, then tighten the tightening nut of the wire rope of the safety mechanism to ensure that the safety mechanism can always lock the lifting head safely and also open it flexibly to a safe state; finally, install the protective cover of the safety mechanism.
(3) Cylinder air exhaust
The hydraulic system is equipped with an exhaust screw, located in the top of the cylinder exhaust first lift the head to more than one meter, loosen the top of the cylinder screw plug (do not screw out all the screw plug), discharge the air in the system, and then tighten the screw plug. Then lift the head up and down until the equipment can run at the same speed without shaking. Otherwise, exhaust again.
(4) Adjustment of descending speed
Users can adjust the descending speed according to the demand, the method is: first loosen the throttle valve fixing nut, adjust the throttle valve bolt clockwise, then the descending speed becomes slower, and vice versa becomes faster. Don’t forget to tighten the fixing nut when adjusting to the required speed;
(5) Load test
After completing the above adjustments must be loaded test, test the first low running a few times, check the synchronization of the run and the card release insurance synchronization are consistent, and no other abnormalities and then run the whole process, such as any abnormalities need to repeat the above adjustments.
Tip: the first no-load operation will have a jittery phenomenon, loaded run a few times, to be eliminated naturally after the removal of air from the hydraulic system!
