Product classification and working principle
Conventional mobile：
1.The bottom of the bridge is equipped with universal wheels and a towing rod. It can be moved to the designated position at the rear of the truck by forklift or manual towing. Lower the adjustable support legs on both sides, rotate the support feet to keep them close to the ground, distribute the load on the bridge body, and prevent it from tilting or shaking during operation.
2.Shake the rocker of the hydraulic pump. The pump body will pressurize the hydraulic oil in the oil tank and then convey it to the lower end of the lifting cylinder through the check valve.
3.High-pressure hydraulic oil drives the piston of the oil cylinder to move upward, and the piston lifts the bridge plate as a whole. The height of the bridge plate can be precisely adjusted by repeatedly shaking the joystick until the lip plate is higher than the floor of the truck compartment.
4.The principle of descent: When the unloading valve of the hydraulic system is opened, the hydraulic oil in the cylinder loses pressure and flows back to the oil tank through the unloading valve.
5.The bridge plate descends slowly under its own weight and load pressure. The descent speed can be adjusted by controlling the opening degree of the unloading valve. Ultimately, the lip plate should be tightly overlapped with the floor of the vehicle compartment (with an overlap length of ≥150mm), meeting the passage conditions for forklifts.
Folding mobile type：
1. Storage → Unfolding process (Core folding logic)
Unlock the folding mechanism:Loosen the lock clips on both sides of the secondary bridge and pull out the safety pin.
Unfold the secondary bridge: Pull the telescopic rod to flip the folded secondary bridge upwards to be level with the main bridge. Reinsert the safety pin and fasten the snap fasteners to ensure that the surface of the bridge is smooth and seamless.
Position the support legs: Lower the adjustable support legs on both sides, rotate the support feet to keep them close to the ground, distribute the load on the bridge structure, and prevent it from tilting during operation.
2. Lifting adjustment principle (consistent with the conventional manual hydraulic model)
Lifting process: By turning the rocker of the hand-cranked hydraulic pump, the pump body pressurizes the hydraulic oil and delivers it to the lower end of the lifting cylinder. The high-pressure oil pushes the piston upward, raising the bridge plate as a whole until the lip plate height is slightly higher than the floor of the truck body.
Descent process: Slowly open the unloading valve of the hydraulic system. The hydraulic oil in the cylinder flows back to the oil tank. Under the effect of its own weight, the bridge plate slowly descents. The descent speed is controlled by adjusting the opening degree of the unloading valve. Eventually, the lip plate is tightly overlapped with the bottom plate of the vehicle body (overlap length ≥120mm).
Safety protection: Equipped with a small hydraulic lock to prevent sudden falling of the bridge deck due to oil pipe burst; The surface of the bridge deck is made of anti-slip patterned plates, and anti-collision rubber strips are set at the edges.
3. Work Completed → Storage Process
After the forklift is removed, turn the hand pump to raise the bridge plate to the lowest height.
Retract the support legs and release the secondary bridge lock latch and safety pin.
Fold the secondary bridge down to fit the side of the main bridge and fasten the storage lock.
It can be dragged to the storage area by a traction ring or manually pushed.

FAQ
1.Question: How to deal with the situation where the two-fold structure gets stuck when closing or unfolding and cannot be smoothly returned to its original position?
Response: First, clean the debris and debris from the folding hinges, pins and limit clips, and apply lithium-based grease to each moving pin. If the buckle is stuck, correct the deformed part and replace the worn spring to ensure accurate folding positioning without jamming.
2.Question: After the equipment is deployed, there is shaking during operation, which is more obvious when forklifts pass through. How can this problem be solved?
Response: First, confirm that the support legs are fully extended to the ground and the foot pads are not worn, and then lock the mobile wheel brake. If the lead screw of the support leg is stripped, replace the lead screw and install an anti-loosening nut. If the connection between the tabletop and the frame is loose, simply re-tighten the connecting bolts.
3.Question: When moving, if it is difficult to push and the steering is sluggish, which parts should be focused on for inspection?
Response: Prioritize the inspection of the bearings of the moving wheels (apply grease if they are short of oil or replace them directly if they are damaged) and the tire pressure (replenish the tire pressure and replace the worn tires). At the same time, check whether the folding parts are fully folded to prevent the components from sagging and scraping the ground, which may affect movement.
4.Problem: The hydraulic lifting speed is too slow, and it even fails to reach the specified height. How can this be investigated and resolved?
Response: First, check the hydraulic oil level. If it is insufficient, add the same type of anti-wear hydraulic oil. If the oil quality becomes cloudy, completely replace it and clean the oil tank. Check again for any oil leakage in the hydraulic oil circuit. If the pump body pressure is insufficient, repair or replace the hydraulic pump.
5.Question: If there are minor cracks in the weld seam at the folding joint, can it still be used? How should it be handled?
Response: No further use is allowed. Stop the machine immediately. Use high-strength welding materials to repair the cracked weld seams, and do a good job in anti-rust treatment after repair welding. For subsequent use, overloading and violent folding are strictly prohibited. During transportation and storage, it should be firmly fixed to avoid squeezing and collision.
