GuangxiHydraulic boarding bridgeHow to carry out special inspection work

Reasons 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.

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, hoping to bring more help to everyone.

Guangxi.There are many types of boarding bridges, and their respective roles and application fields are also different. Hydraulic boarding bridges, fixed boarding bridges, and mobile boarding bridges are currently common and advantageous equipment on the market, playing a huge role in their respective fields. Below, we will first analyze the development trend of mobile boarding bridges: mobile hydraulic boarding bridges are a good helper for loading and unloading goods on forklifts. Compared to pneumatic tires, mobile boarding bridges are equipped with solid tires with low starting resistance, simple structure, convenient use and maintenance, no need for inflation,GuangxiWarehouse boarding bridge, no hidden dangers of air leakage and tire explosion. And solid tires have good safety durability, puncture resistance, tear resistance, and economy.

The precautions during the use of hydraulic boarding bridges are hoped to be helpful to you.

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

Reasons 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,GuangxiManufacturing of boarding bridges, 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, working height generally ranging from 6 meters to 14 meters, wide working platform vehicle and high load capacity, wide range of high-altitude work, suitable for multiple people working simultaneously. The power form can be selected according to different requirements (such as three-phase AC power supply, single-phase AC power supply, DC power supply, and internal combustion power supply). The manual hydraulic device can lift and retract normally in places with power outage or no power supply, increase the telescopic platform car, and extend to necessary positions in case of insufficient length of the platform car, improving work efficiency.

The reason for the natural descent of the hydraulic boarding bridge lifting platform is that the one-way valve is leaking, the lowering valve is not tightly sealed, and the oil cylinder is leaking. Solution: Check the one-way valve in the valve group. If dirt is found on the sealing surface of a single valve, clean the one-way valve. Check if the lowering valve has power. If there is power troubleshoot the lowering valve itself or replace the lowering valve. The slide valve of the lowering valve must be kept clean and move flexibly.

management.During the excavation process of the foundation pit of the simple boarding bridge, collision of the support structure should be prevented, and changes in the soil wall should be paid attention to at all times. If any abnormal phenomena such as cracks are found, construction must be suspended and reported to the superior for handling.

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.

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 width of the boarding bridge also requires a certain width of its own. However, if the width is too small it is not conducive to forklift loading and unloading of goods. If the width is too large, which is not necessary. So a reasonable width is necessary, usually the width of the electric hydraulic boarding bridge is 1800mm, 2000mm, the internal width is the width of the passage, and the total width mainly refers to the width of the guardrails on both sides plus the width of the passage. The total width can be ignored in use, but everyone still cares about the internal width, which is the width of the channel.

Installation conditions.　　1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.

There are the following: (1) The brake of the elevator should be regularly inspected to see if its clearance is appropriate, as well as some other aspects, in order to ensure its flexibility and reliability in use. In addition,GuangxiCar boarding bridge, on the friction surface of the brake, it is necessary to check for any dirt, and if any, it should be cleaned in a timely manner. (2) For the part of the moving boarding bridge, it should be carried out in accordance with the specified requirements, and it should be comprehensive and sufficient without any omissions. However, the amount of oil should not be too much, as too much can also cause problems.

The hydraulic boarding bridge not only reduces labor intensity, 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.

Guangxi.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, the lifting platform must not be moved, 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, 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.

Nowadays, 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.
