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

For slopes that are unstable or unstable after earthwork excavation, top-down segmented trench jumping should be adopted based on the geological characteristics and possible situations of the slope and reverse construction or partial reverse construction should be carried out in a timely manner. It is strictly prohibited to excavate and explode indiscriminately.

Oberhausen.Check the hydraulic oil quality and level. When the lifting platform is raised to a high position, the hydraulic oil level should be 40-50 millimeters higher than the bottom of the oil tank. When the color of the hydraulic oil darkens, the oil becomes sticky, or there are foreign objects such as gravel in the oil, the hydraulic oil should be replaced in a timely manner. The hydraulic system of the lifting platform should be checked for hydraulic and pipeline connections. If the pipeline is damaged, it should be replaced immediately; When there is looseness in the connection part, tighten the pipe joint.

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, 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.

.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.

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

Operation degree: There are two types of operations that can be used to raise and lower the boarding bridge. One is a manual pump station, which uses manual hydraulic lifting, which is labor-intensive and somewhat labor-intensive. Advantages: It can be operated and used in any situation. Two types of electric pump stations use electric hydraulic lifting and lowering, which reduces labor intensity and saves labor. Disadvantage: Once the power is cut off, but now there are both manual and electric boarding bridges that are more convenient to use.

What is a hydraulic boarding axle? The hydraulic boarding bridge is a special auxiliary equipment used for fast loading and unloading of goods, and its height adjustment function can build a bridge between the truck and the warehouse platform. What are the operational steps we take during use?

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,OberhausenFixed hydraulic boarding bridge, 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.

During excavation, if unidentifiable items or unforeseeable situations are found, the operation should be stopped in a timely manner and reported to the person in charge of the hydraulic boarding bridge for handling. The fixed boarding bridge is an auxiliary equipment for loading and unloading in conjunction with the storage platform. This equipment is integrated with the platform and can be adjusted up or down according to the different heights of the truck carriage, making it convenient for forklifts to enter the carriage. The equipment adopts an imported hydraulic pump station with anti rolling skirts on both sides, making work safer and improving work efficiency.

Recommendation and consultation.When working in foundation pits or depths, as overloading may cause damage to objects; Working on a lifting platform without protective barriers may cause personnel to fall and cause casualties.

Common&quo; Work” Steel structure planning can withstand uniform pressure,OberhausenFixed boarding bridge, reduce skeleton torque, and be more robust than other channel structures.

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, and replace it if it is damaged or severely worn.

retailer.Slowly reverse and park the container under the lip at the front of the boarding bridge.

(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.

When it comes to fixed hydraulic boarding bridges I believe

Oberhausen.Tighten the manual valve to close it.

Install drainage ditches on the ground near the pit of the simple boarding bridge, and take corresponding drainage measures for the top, surface, and foot of the slope,OberhausenEmbedded boarding bridge, especially for the simple boarding bridge.

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.
