How to choose the most suitable car lift 



Car lift is automotive repair equipment for lifting cars, which plays an essential role in car maintenance field, whatever overhaul or small area repair.
 
  It can be divided into four kinds: single post car lift, two post car lift, four post car lift and scissor lift.
 

1. Single post car lift

  Single post car lift is easy operated, with decent and elegant appearance. It can be movable and fixed, save floor space. Movable model is adaptable for indoor and outdoor maintenance. while fixed single post car lift usually installed indoor.
 
 
  Here is another popular single post car lift for car wash, especially for vehicle chassis cleaning. The body shell and cylinder use anti-corrosion, anti-rust and chrome-plated treatment, so it's waterproof and can be used in water. Upper support frame can be rotated 360°and lifting height can reach more than 1800mm.

 
 
 
 
 

2. Two post car lift

  Two post car lift is common used for lifting small cars. While lifting cars, it can save a lot ground space to make repair work more convenient. Two post car lift has high expectations for the foundation if there is no base board and beam. It's material and cost saving compared with four post lift.
 
  Clear floor and floor plate two post car lift are commonly seen in the market.
  Both of their lifting height are 1850mm. And capacity 3.5t, 4t and 5t are optional.
  Without base board, clear floor two post lift with beam at the top will make passageway smoothly when the car is lifted. Oil pipe and cable are fully concealed throught the beam, so they won't be easy to get worn. It's lifting height is 1850mm and overall height for the post is 3840mm, so it requires a place with more than 4000mm height.

  If your garage is below 4 meters' high but higher than 3 meters, floor plate two post car lift would be your best choice. It's oil pipe and cable are concealed through the base board on the ground, so the base board is a barrier and it might easily get wear and tear.



 
  Symmetric and asymmetric installation types are optional for clear floor model. The arms' length of the four arms for the symmetrical lift are approximately equal, so that the center of the car (or the center of mass) is in the middle of the column. For the daily maintenance of cars such as pickups and box trucks, this symmetrical lift can be the best choice. But for some of the symmetrical double column lift  whose column width is not large enough, it is a big drawback when the car door cannot open  after lifting. The column of the asymmetric lift is rotated backwards by an angle (about 30 °) and the forearm is slightly shorter than the rear arm. When the car is parked in the appropriate location of this asymmetric lift, the car position will move back in a way.



3. Four post car lift

Four post car lift is commonly used as special mechanical lifting equipment for large tonnage cars or trucks repair and maintenance. It's driven by hydraulic cylinder , full-scope mechanical safety locking by locking latch ,manual lowering. Some of the four column car lift is suitable for four wheel positioning, because they are equipped with turntable, sliding plate and secondary lift.

Compared with other car lifts, four post car lift is safe and multifunctional, but it occupy too much space, not convenient for small area workshop.




4. Scissor car lift

   Scissor car lift is scissor design, electric drive and mechanic transmission structure. It's widely used in large vehicle maintenance workshop. Scissor lift is moderate in speed and does not occupy space. And because it's simple structure and good synchronization, scissor lift is commonly used as a four-wheel locator platform. 

   There are big scissor lift with secondary lift, small scissor lift and ultra-thin scissor lift for your choice. Small scissor lift is mainly for car repair and maintenance, safe and convenient in operation. Big scissor lift can work for four wheel positioning, car repair, changing wheels and chassis checking. In-ground and on-ground installation are optional.

 
 

 
 
 
 
 
   
  Low rise scissor lift is small volume design, suitable for quick repair shops for tire changing and repairing light weight. It's easy for moving, no need dig foundation. Safety lock system, easy to control, safe and reliable.





   Compared with four post lift, scissor lift can release more space and more convenient for transportation. All the cylinders are equipped with explosion-proof valve to prevent the sudden decline when the cylinder stops work, to ensure operations' safety.
 
   To ensure the safe operation, operators should: (1). clear area when raising or lowering vehicles. (2). Daily inspect the safety block mechanism to ensure the safe operation. Adjust or repair the safeties immediately if find abnormalities. (3). Daily inspect the working condition of steel rope and replace the damaged rope immediately. (4). Lifting or lowering is not allowed while someone is working. (5). Stop working when operation is not flexible, the hydraulic part leakage oil and other accidents. (6). Doing regular check for cylinder and oil volume.




Lift Adjustment


1. Lubricate contact surface of the carriage and corners of column with general-purpose lithium grease. All sliding surface should be coated evenly from top to bottom. 2. Fill hydraudlic oil N32 or N46 to the oil reservoir of the power unit. 


Adjustment procedure



1. Check to see if the power supply is installed properly.2. Check for the tightness of all the connecting bolts. 3. Press the starting button on the motor and the carriage rises. Stop pressing the button. Then the carriage will stop. In order to lower the carriage, first pull the steel rope for releasing safety locks on the two carriages one time for each. In case of failure to pull the wire, re-pull after raising carriage a little. Press the lowering handle on the power unit and the carriage will be lowered. Stop pressing the handle. Then the carrige will be lowered. Stop pressing the handle. Then the carriage will stop. In case of vehicle repairing. When the vehicle is lifted up to the required height. First press the oil release handle to actuate the mechanical safety lock in order to ensure the safety operation. 4. The hydraulic system may contain air due to new installation, to bleed the air, repeat the lifting and lowering for serveral times.5. The adjustment is completed.
