Zory Mobile boReasons for the hydraulic boarding bridge lifting platform not lifting: low voltage, motor not rotating,Zory The boarding bridge is movable, 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.
What should I pay attention to when choosing a boarding bridge? The selection and purchase of the boarding bridge involves paying attention to three issues, including its range of use, rated load, and other factors; Their understanding of the manufacturer of the boarding bridge, whether their enterprise qualifications, special equipment licenses are complete, how many after-sales service outlets are there in the country, how about their after-sales service attitude, and whether they are timely; The important point is whether the quality is good or not, and whether the price is reasonable. If both of these situations are reasonable, you can choose the products of the manufacturer.
Zory .For the safety performance of high-altitude work platform vehicles, it is necessary to have production technology, scientific processes, and strict management to ensure production. When in use, people, the environment, and machines are the three major links of high-altitude operations, and safety is the basic condition to ensure the smooth progress of high-altitude operations. In the following text, Jiuyi briefly describes the precautions for using high-altitude operation platform vehicles: high-altitude operators must hold a health certificate. Individuals with mental illness hypertension, or mental illness are not allowed to engage in high-altitude work tasks. Staff are not allowed to engage in high-altitude work while drinking alcohol or feeling mentally drained.
When it comes to fixed hydraulic boarding bridges, unloading suitable for places where loading, 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
When confirming that the lip is fixed to the container, pull out the hook to hook it into the container, tighten the chain to ensure that it does not loosen,Zory Mobile cllimbing, and press the brake blocks on both sides. The boarding bridge is already a very visible structural form in modern logistics sites. It is the point and endpoint of the enterprise logistics chain, and a loading and unloading operation platform for enterprises to quickly and safely turnover products and goods. The height of the loading and unloading operation platform is fixed, rated load including its range of use, and other factors; Their understanding of the manufacturer of the boarding bridge, whether their enterprise qualifications, special equipment licenses are complete, how many after-sales service outlets are there in the country,Zory Mobile Yard Ramps , how about their after-sales service attitude, and whether they are timely; The important point is whether the quality is good or not and whether the price is reasonable. If both of these situations are reasonable, you can choose the products of the manufacturer.
What are the issues to pay attention to when using the boarding bridge? For example, mobile boarding bridges are generally used outdoors, and after use, rain, and sunlight, the maintenance of the boarding bridge is very important. When it rains, stable and safe, with a wide range of operations.
Shake the handle to raise the boarding bridge to the height of the container.
Total quality management.Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
When it comes to fixed hydraulic boarding bridges, I believe
Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
1. Before use, check the boarding bridge for obvious damage such as cracks and broken wires.
original.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.
Please check if the power supply is stable and if there is a disconnection in the circuit. If everything is checked to be normal, it should be considered whether there is built-in power
The safety valve of the mobile hydraulic boarding bridge can also generate high noise. When air is mixed into hydraulic oil, the relief valve gets stuck or severely worn, and the fatigue deformation of the relief valve spring leads to unstable pressure regulation of the relief valve. The pressure release time of the relief valve is too short, which can easily lead to local stability of the pilot valve performance of the relief valve. Noise is generated by the vibration of the pilot valve's air. Therefore, we should regularly clean the safety valve, and replace it if it is damaged or severely worn.
Zory .Reason for the lifting table not lowering: The lowering valve is malfunctioning, and the lowering speed valve is out of adjustment. Solution: When pressing the lowering button, check if the lowering valve is energized. If there is no electricity, try to eliminate it; If there is electricity, troubleshoot the lowering valve itself or replace the lowering valve. The lowering valve should be kept clean.
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.
Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!
