ClevelandMobile boarding bridge brandCauses of surface corrosion

During use, close attention should be paid to the condition of the equipment, and if there are any problems, the use should be stopped immediately.

To ensure that the hydraulic boarding bridge is in good condition, it should be checked in advance before use, mainly including whether the buttons are effective; Whether the power cord and socket are intact; Whether the oil pipeline is intact; The stability of the guardrail; The tightness of bolts at each junction point; The appearance quality is intact. But when the power is turned on and the indicator light is on, press the up button, the motor rotates but the lifting table does not rise. This may be due to the reverse connection of the three-phase power supply and the motor reversing. Only the power supply needs to be corrected, so it is not a major problem.

Cleveland.Check the rollers intermediate shafts, and bearings; Oil cylinder pin and bearing; Equality and wear of the hinge shaft and bearings of the boom; Add oil to the above components for maintenance of outdoor elevators and factory elevators. Extend the service life of bearings. Professional axle manufacturers and other special products, 20 year old brand, with price advantages and guaranteed quality

.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.

The slope of the electric hydraulic boarding bridge itself must have a certain slope to allow the forklift to enter the carriage for cargo loading and unloading. The length of the slope also varies from 7000mm to 7500mm, mainly considering safety and stability of use. For a long time, the manufacturer of the boarding axle has no turnover to avoid the price difference, which is 20% higher than the market value! More than one ton is more expensive!

Check if the manual valve is open. When using, it must be opened otherwise the boarding bridge may be damaged.

The hydraulic boarding bridge not only reduces labor intensity, but also doubles the efficiency of loading and unloading operations, accelerates logistics speed, and achieves significant economic benefits. Hydraulic loading and unloading bridge is a specialized auxiliary equipment for fast loading and unloading of goods. Its height adjustment function allows a bridge to be built between the truck and the cargo platform in the warehouse. Forklifts and other transport vehicles can directly enter the truck for batch loading and unloading of goods, also known as loading and unloading platforms.

(4) For the connection parts of the mobile boarding bridge, careful inspection should be carried out to check for any looseness such as connecting bolts. If there are any, they should be tightened in a timely manner. In addition, for all connecting shafts, there should be split pins that are thick and sufficient.

Tighten the manual valve to close it.

new product.The correct operation of the hydraulic boarding bridge is good maintenance,ClevelandMounted axle hydraulic fixed type, and how to operate it correctly. Let me briefly introduce the operating steps of the hydraulic boarding bridge, hoping to bring more help to everyone.

Reasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, 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, 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.

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.

These are the options for hydraulic oil for mobile boarding bridges.

A complete range of products.Check if the manual valve is open. When using, it must be opened, otherwise the boarding bridge may be damaged.

When conducting high-altitude operations on dangerous edges such as roofs, suspension bridges, slopes, or cliffs, guardrails or safety nets should be installed on the side facing the air, or safety belts or ropes should be used.

When working on the hydraulic boarding bridge, the support legs must be extended, and the support leg bolts must be adjusted to ensure that the lifting platform is stably stressed on the support legs and kept horizontal; During the lifting process and in the lifting state,ClevelandTelescopic boarding bridge, the lifting platform must not be moved,ClevelandTrain boarding bridge, and it is strictly prohibited to shake on the lifting platform. If there is an abnormal sound during the operation of the hydraulic boarding bridge, it should be stopped immediately for inspection to avoid causing serious damage to the lifting platform; Before use, check whether the electrical equipment is normal; All shaft pin oil holes must be oiled before each use. Before use, it is necessary to perform no-load lifting and check whether the hydraulic system is normal; The load of the workbench should not exceed the rated value, and it should not be subjected to intense manual shaking; The hydraulic oil in the oil tank must be replaced every 500 hours of operation.

Cleveland.The hydraulic boarding bridge is a specialized auxiliary equipment for achieving rapid loading and unloading of goods, and is our good helper. However, malfunctions during use are inevitable. What should we do when encountering a malfunction?

Shake the handle to raise the boarding bridge to the height of the container.
