KercladHydraulReasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating, motor reverse, motor phase loss (motor not moving and buzzing), indicator light on, press the up button, motor rotates but lifting platform does not rise, lowering valve is open, overflow valve pressure is low, oil level is too low, oil pump is empty, oil suction filter is blocked, oil suction section is leaking, and two phases in the three-phase line are arbitrarily changed; Solution: Check the starter potential during motor load operation. Voltage hydraulic range allowed± １０％； Check the motor and circuit; Check the circuit breaker and motor wiring; When the lowering button is released, use a voltmeter to check whether the lowering valve is energized. If there is no power check the circuit and eliminate the fault; If there is electricity, eliminate the malfunction of the lowering valve itself. The slide valve of the lowering valve must be kept clean and move flexibly. Readjust the overflow valve. Adjust at 100% rated load; Fill up the hydraulic oil; Clean the filter; Check the oil suction pipe and joints; Tighten the joint and replace it if necessary.
Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
Kerclad.(5) Each mechanism in the elevator should be checked for normal operation and any noise or other malfunctions. If any they should be promptly addressed and resolved. All wires and cables in the mobile boarding bridge should be checked for any damage or damage, and if any, they should be promptly wrapped or replaced with new ones.
The correct operation of the hydraulic boarding bridge is good maintenance, and how to operate it correctly. Let me briefly introduce the operating steps of the hydraulic boarding bridge, motor not rotating, motor reverse motor phase loss (motor not moving and buzzing), indicator light on, press the up button, motor rotates but lifting platform does not rise, lowering valve is open, overflow valve pressure is low, oil level is too low, oil pump is empty, oil suction filter is blocked, oil suction section is leaking, and two phases in the three-phase line are arbitrarily changed; Solution: Check the starter potential during motor load operation. Voltage hydraulic range allowed± １０％； Check the motor and circuit; Check the circuit breaker and motor wiring; When the lowering button is released, use a voltmeter to check whether the lowering valve is energized. If there is no power, check the circuit and eliminate the fault; If there is electricity, eliminate the malfunction of the lowering valve itself. The slide valve of the lowering valve must be kept clean and move flexibly. Readjust the overflow valve. Adjust at 100% rated load; Fill up the hydraulic oil; Clean the filter; Check the oil suction pipe and joints; Tighten the joint and replace it if necessary.
When replacing hydraulic oil, sometimes poor hydraulic oil can also cause noise on the hydraulic boarding bridge, as well as noise when the pump station enters the air.
Portable hydraulic press boarding bridge: It is a widely used type, suitable for places where loading, unloading, and transportation are not fixed or moving; Mobile hydraulic press boarding bridge: suitable for fixed and immovable goods such as ports, cargo platforms, warehouses, etc
Open the manual valve, slowly lower the boarding bridge,KercladMobile hydraulic loading and unloading boarding bridge, and secure more than 90% of the lip plates at the bottom of the container.
The outstanding characteristics of air suspension are good smoothness, less maintenance, long service life, significant improvement in protection of cargo compared to steel plate suspension, and greatly reduced damage to the entire vehicle and road surface. The leaf spring produces different bending under different loads, so the distance between the whole vehicle and the ground is always changing. If the load is increased while keeping the spring unchanged, it will also reduce the natural frequency of the spring and even change the characteristics of the spring. The air spring is based on the compressibility of air. The air enclosed in the air bag is an element. Different air bag pressures of the air spring system balance different loads. When the height of the air bag is fixed, the distance between the car body and the road surface remains unchanged.
The hydraulic system adopts imported Italian brand products, with excellent performance and minimal maintenance. The oil cylinder lifting power system, inclined plate,KercladLifting and disembarking bridge, and small oil cylinder operation, can be adjusted smoothly. The height adjustment plate is a selected decorative plate and profile, with a long service life. Various qualified manufacturers of boarding bridges are welcome to inquire by phone and sincerely invite cooperation!
technological innovation.There is a flip plate at the top of the bridge deck, which is placed at the edge of the carriage to ensure a smooth transition between the passage and the carriage. Its advantages are as follows.
Open planning before placement makes it easy to clean up clutter.
During the excavation process of the foundation pit of the simple boarding bridge collision of the support structure should be prevented, construction must be suspended and reported to the superior for handling.
Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, the electric hydraulic boarding bridge has become a loading and unloading tool used by many companies. Compared to many friends, I am still not very familiar with electric hydraulic boarding bridges. Below, the editor will explain the product parameters and specifications related to the length, slope, and height of the electric hydraulic boarding bridge.
