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

The length of the electric hydraulic boarding bridge is generally about 10 meters, and the bearing weight varies depending on the tonnage. It is 10500mm for 6 tons, 11200m for 8 tons, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.

Swarth.Applicable scenarios: municipal road engineering inspection, street lamp maintenance, branch construction, signboard maintenance, etc.

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.

.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.

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.

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.

When working in foundation pits or depths, a helmet must be worn.

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,SwarthThe boarding bridge is movable, the oil becomes sticky, 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.

After the boarding bridge work is completed all parts should be scrubbed and cleaned. When not working, the workbench should be lowered to a low position.

middleman.The pressure on the axle will reduce the service life of the boarding axle.

Do you know some of the working characteristics of hydraulic lifting boarding bridges? Today, I will take you to understand!

There is a lot of noise generated when using a mobile hydraulic boarding bridge. So, where are these noises caused? In fact, pump stations, steel cylinders, and steel equipment are all sources of noise. Today we will analyze for you: 1. 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, but there is always a certain height difference or gap between the transportation vehicles and the loading and unloading platform due to the height of the carriage. Causing the forklift to be unable to enter and exit the transportation vehicle for direct loading and unloading of goods. Use the boarding bridge to provide reliable connections. Enable forklift trucks to safely and quickly enter and exit transportation vehicles for loading and unloading operations. After hearing the noise from the hydraulic boarding bridge, first check if there are any problems with the hydraulic pump station, valve, and fixing device, 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.

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

Outdoor elevators and factory cargo elevators are heavy lifting mechanical equipment. Outdoor elevators are used for transporting goods between floors of buildings, and are specialized hydraulic cargo elevator products. They are mainly used for transporting goods up and down between various working floors; Vertical garage and car lift between garage floors. The hydraulic system of the product is equipped with anti fall and overload protection devices, and operation buttons can be set on each floor and lifting platform workbench to achieve multi-point operation. Long term promotion of axle manufacturers' complete products excellent quality, and discounted prices

During the application process of hydraulic boarding bridges, it is necessary to follow the operating procedures to ensure the normal operation of the equipment. What precautions should we take when using hydraulic boarding bridges?

Swarth.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 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 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, check whether the electrical equipment is normal; All shaft pin oil holes must be oiled before each use. Before use,SwarthTrain boarding bridge, 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.

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