How to solve the common problems of semi trailer landing gears for sale

1. Retraction of the semi trailer landing gears for sale

When the two-way hydraulic lock is intact, the semi trailer landing gears generally do not retract due to the incompressibility of the liquid. When the semi trailer landing gear is retracted, if it’s been checked that the oil seal in the vertical cylinder is in good condition, the main reason for retraction may be due to the damage of the hydraulic lock of the semi trailer landing gear. Any debris in the hydraulic lock should be removed or a new lock should be replaced.


2. The falling of the semi trailer landing gear

  • The main reasons for the falling of the semi trailer landing gear on its own during driving or parking.

  • The oil seal in the vertical cylinder is damaged.

  • The two-way hydraulic lock of the semi trailer landing gear is damaged.

  • If the hydraulic lock is intact, it is caused by the damage of the oil seal in the vertical cylinder. The falling distance is generally limited and the oil seal can be replaced at this time. If the two-way hydraulic lock is damaged, the falling distance of the semi trailer landing gear will be large.


3. Failure to retract and release the semi trailer landing gears for sale

When the vertical semi trailer landing gear is being retracted, a certain horizontal semi trailer landing gear extends out. When the horizontal semi trailer landing gear is being retracted, a certain vertical semi trailer landing gear extends out. Generally, the corresponding horizontal cylinder and vertical cylinder oil seal is damaged. If a certain horizontal cylinder or vertical cylinder is weak or does not move, the corresponding hydraulic cylinder oil seal is damaged or even the cylinder is pulled.

 

 


Operating Specifications for Semi trailer landing gears for sale

Preparation before operating the semi trailer landing gear for sale

The size of the semi-trailer traction head and traction pin should be checked before use to ensure matching

Carefully check whether there is sand, dust or other foreign objects on the working surface of the saddle of the tractor, the traction pin, and the traction skid of the semi-trailer. It should also be checked whether there is enough lubricating grease.

Before the semi trailer landing gears are extended, the pressure bearing capacity of the ground should be understood. The material, grounding area and grounding position of the backing plate should be reasonably selected to prevent the semi trailer landing gears from sinking during operation. The parking brake should be engaged and the semi trailer landing gear pin should be pulled out.

 

Normal operation of semi-trailer semi trailer landing gears for sale

  • Only low-speed gears are allowed to be used when the vehicle is lifted off the ground, and high-speed gears are not allowed;

  • Correctly remove the semi trailer landing gear crank handle from the crank handle hook, pull the crank handle to the horizontal direction, hang the gear correctly (generally pull out for low gear, push in for high gear), and correctly set the round hole at the root of the crank handle into the rotating shaft.

  • When the operator shakes the mechanical rocker by hand, he must stand on the side and rear of the semi trailer landing gear, with one hand on the rotating shaft of the rocker and the other hand shakes the semi trailer landing gear handle with force;

  • When cranking the handle each time, it must reach the lower level of the entire circle before letting go. Even if the rocker arm rebounds, there is a margin of 3/4 for each round so no injury will occur;

  • After each operation, the crank handle should be pulled out from the rotating shaft, placed in a vertical direction, and snapped into the crank handle hook.

Precautions during the operation of the semi trailer landing gear

  • When the semi-trailer is fully loaded, the force applied to the handle shall not exceed 196N;

  • During the operation, when using a low gear, if there is abnormal force, stop the operation and report it to the maintenance personnel for inspection;

  • When extending the semi trailer landing gears, pay attention to the order of extension. Generally, the rear semi trailer landing gears are extended first, then the front semi trailer landing gears are extended. The order is reversed when retracting the semi trailer landing gears.

  • When a crane with an engine is installed on the vehicle, after the semi trailer landing gear has been extended, the engine should be turned off and the driver should be placed in the neutral position;

  • Once the semi trailer landing gears has been setup, the ground condition of the vertical semi trailer landing gears should be checked again before the lifting operation is officially carried out. The phenomenon of “three legs” shall not appear;

  • When the operation is completed, if any rebound phenomenon is found, it is forbidden to forcibly put it into the hook of the crank handle to prevent the crank handle from popping out of the hook and hurting people.

Semi trailer landing gear for sale maintenance

  • After the semi trailer landing gears are used, all parts should be scrubbed and cleaned, and the semi trailer landing gears should be lowered to the lowest position when not in use to prevent the surface of the piston rod from rusting;

  • If there is an abnormal sound when the semi trailer landing gear is working, stop the operation immediately to avoid serious damage to the semi trailer landing gear. Check whether the electrical equipment is normal before use and add lubricating oil to all oil holes before each use.

  • In order to ensure that the semi trailer landing gears of the trailer are in good working condition, it is necessary to check whether the control button is effective, whether the power cord and socket are in good condition, and whether the oil pipeline is in good condition. The stability of the guardrail, the tightness of the bolts at each connection point, and wheather the appearance quality is intact should also be checked.

  • The semi trailer landing gears should work strictly according to their specified carrying capacity. Overloading work may cause damage to personnel and goods. Working on a lifting platform without safety guardrails will cause personnel to fall and cause casualties.
