Product Classification
Classified by power drive mode
1.Manual hydraulic model: Driven by a hand-cranked pump for lifting, no external power supply required, manually operable, suitable for temporary loading and unloading scenarios without power supply.
2. Electric-hydraulic model: The motor drives the hydraulic system, allowing for one-button lifting and lowering, which is more efficient and suitable for high-frequency operations with power supply.
Working Principle
1.Unlock the storage lock, pull out the safety pin, and release the locking state of the three-section folding of the bridge body.
2. Pull the two auxiliary bridge tie rods in sequence, flip them to be level with the main bridge, and tighten the pins to achieve seamless connection.
3. Lower the adjustable support legs, tighten the support feet and keep them close to the ground to ensure the stability of the bridge operation.
4. Hydraulically driven for lifting, the manual version uses a pump to increase pressure and lift the bridge, and opens the unloading valve to lower the bridge. The electric version can adjust the height with one button and precisely connect to the truck body.
5. After the operation is completed, lift the bridge and retract the legs. Unlock the secondary bridge in sequence, fold it to fit the main bridge, and fasten the lock to move and store it.
Product Application
1.For fixed small loading and unloading points with limited space such as narrow alleys in warehouses and the back doors of supermarkets and convenience stores, the three-fold compact structure can be unfolded for immediate operation. After folding, it can be attached to the wall for storage, completely not occupying the limited operation and storage areas.
2. Temporary distribution points for community group buying and small retail stores can be quickly deployed without fixed platforms. They can be displayed as needed and collected immediately after use, effectively solving the problem of height differences during loading and unloading of small and scattered goods.
3. Small logistics transfer warehouses and regional distribution points, lightweight and easy to tow and transfer, can be adapted to delivery trucks of different tonnages, meeting the frequent and multi-vehicle type of scattered goods turnover and loading and unloading needs.
4. Temporary material stations for construction sites and decoration sites can be put into use immediately upon arrival without the need for infrastructure construction. They can be easily connected with engineering vehicles and trucks to facilitate the convenient loading and unloading of building materials and small hardware items.
5. Short-distance delivery points for fresh fruits, vegetables and daily necessities are suitable for various temporary loading and unloading scenarios outdoors. They are flexible to move and easy to operate, effectively improving the loading and unloading efficiency of short-distance delivery and reducing the time consumed for goods transfer.
Company Strengths
Our company focuses on the core research and development and production of three-fold mobile loading Bridges. With mature folding structure optimization technology and rich scene adaptation experience, we have built a differentiated competitive advantage. To address the pain points of working in confined Spaces, the three-section folding hinge design has been optimized. Wear-resistant and corrosion-resistant high-strength alloy materials are selected, and a precise hydraulic control system is used to achieve rapid folding and storage of the bridge body as well as smooth expansion. After folding, the occupied space is only one-third of that in the expanded state, making it suitable for extreme space scenarios such as warehouse narrow alleys and temporary distribution points. We can customize manual/electric hydraulic drive modes and load-bearing specifications ranging from 3 to 10 tons according to the customers' operational requirements. At the same time, we provide personalized configurations such as anti-slip, explosion-proof and anti-freezing to meet the needs of various indoor and outdoor working conditions. As an integrated service provider, we strictly adhere to quality control standards from raw material procurement to finished product delivery. Our equipment is equipped with standard safety components such as anti-drop hydraulic locks and reinforced support legs. We also offer rapid production and delivery, on-site installation and commissioning, as well as localized after-sales maintenance services.

Balance work efficiency and long-term safety in use.
FAQ
1.Question: The three-fold section suddenly gets stuck halfway through its unfolding, and the hydraulic system shows no response. Even after restarting, it cannot continue to unfold or close. How should this be handled?
Response: First, inspect the travel limit switches of each folding section of the equipment. It is highly likely that the limit switches have been jammed by debris or the contacts have poor contact. Clean the soil around the limit switches, correct the offset switch contact pieces, and wipe the contacts with a dry cloth to ensure good contact. Check again whether the emergency stop button of the hydraulic system was accidentally touched. Reset the emergency stop and then operate again. If there is still no response, check whether the joints of the hydraulic circuit are loose. Tighten the joints and it can be restored.
2. Question: During operation, the middle folding section slightly sank. When the forklift reached this position, the bridge body shook more severely. What could be the reason for this?
Response: The core issue is the wear of the auxiliary support bushing in the middle folding section and the loosening of the connecting bolts of the support arm. First, stop the machine and lower it onto the platform surface. Then, tighten all the connecting bolts of the support arm and install anti-loosening gaskets. Replace the worn support bushing, apply grease to the new bushing, and at the same time check whether the load-bearing crossbeam in the middle section has any slight deformation. Slight deformation can be corrected by cold calibration, while severe deformation requires reinforcement and welding.
3. Question: When moving, the entire device veers off course. When pushed, one side is lighter than the other. When turning, it veers to one side. How can this issue be identified and resolved?
Response: First, check if the pressure of the moving tires on both sides is inconsistent. Replenish the tire pressure and keep it consistent on both sides. Check again for any jamming of the bearing on one side of the moving wheel or incomplete release of the brake. Clear the debris from the bearing, apply grease, and adjust the brake spring to ensure the brake is fully reset. At the same time, check whether the connection between the traction rod and the chassis is eccentric, correct the connection position of the traction rod, ensure that the force is centered, and avoid deviation during movement.
4.Question: When hydraulic lifting occurs, there is a distinct "hissing" abnormal sound, a large number of air bubbles are mixed in the oil, and the lifting efficiency drops significantly. How should it be handled?
Response: This is caused by air entering the hydraulic oil circuit. First, lower the tabletop to the lowest point, unscrew the exhaust valve at the top of the hydraulic oil tank, then slowly raise and lower the tabletop 2-3 times to expel all the air in the pipeline, and then close the exhaust valve. Check if the hydraulic oil level is too low, replenish the same type of anti-wear hydraulic oil to the standard liquid level, and at the same time check if air is entering each joint of the oil circuit. Tighten the joints and replace the damaged sealing rings to prevent air from entering again.
5.Question: After folding, the three-fold section does not fit tightly, with gaps and one side lifting. The equipment is unstable when placed and scratches the ground when moved. How can this be solved?
Response: First, check whether the positioning limit blocks of each folding section are worn or deformed. Replace the worn limit blocks, correct the deformed limit structure, and adjust the limit spacing of each section. Check again for inconsistent elasticity of the tension springs on both sides of the folding hinge, and replace them with springs that match the elasticity to ensure uniform force distribution on each section during folding. Finally, check whether the support foot pads at the bottom of the countertop are uneven in height. Adjust the height of the foot pads to ensure that the equipment fits smoothly and without lifting edges after retracting.
