Common&quo; Work” Steel structure planning can withstand uniform pressure,RubinRetractable boarding bridge, reduce skeleton torque, and be more robust than other channel structures.
Rubin.Function: Convenient unloading, strong stability, and low maintenance cost. Suitable for various vehicles on loading and unloading sites and places with relatively busy traffic. Loading and unloading platform vehicles, lifting platform vehicles, and unloading platform vehicles: Anti slip device: This device is welded from steel plates, which can effectively achieve anti slip function and is reliable.
Install a 5m high protective railing around the foundation pit of the simple boarding bridge, with a distance of no less than 1m from the protective railing to the foundation pit. The mobile boarding bridge only requires a single person to operate, without the need for power supply,RubinTrain boarding bridge, and can achieve safe and fast loading and unloading of goods. Mobile boarding bridges are widely used in cargo platforms and mobile loading and unloading sites without loading and unloading equipment. They are auxiliary equipment for cargo loading and unloading that is used in conjunction with forklifts. The sequence of earthwork excavation must comply with design conditions and follow" Trenching support, support first and then excavation layered excavation, no overbreak&rquote; The principle of.
.It is strictly prohibited to apply excessive pile loads around the foundation pit.
Common&quo; Work” Steel structure planning can withstand uniform pressure, reduce skeleton torque, and be more robust than other channel structures.
Shake the handle to raise the boarding bridge to the height of the container.
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.
In the economic field, the safety, flexibility, and price to efficiency ratio of transportation are directly related to the fate and survival of enterprises due to different road conditions. Therefore, people have high expectations for commercial freight hydraulic boarding bridges, especially those that serve as the main components of trailers and semi trailers. Continuously developing, developing, and producing multiple series and varieties of hydraulic boarding bridges to meet the needs of modern cargo transportation. Below is an introduction to the characteristics of the hydraulic boarding bridge suspension system.
Check if the manual valve is open. When using it must be opened, otherwise the boarding bridge may be damaged.
knowledge.The hydraulic lifting boarding 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 handling vehicles can directly enter the truck for batch loading and unloading of goods, and single person operations can achieve fast loading and unloading of goods. Reduce a large amount of labor, improve work efficiency, and achieve greater economic benefits for enterprises.
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?
Slowly reverse and park the container under the lip at the front of the 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.
Industry management.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 pump is empty, oil suction filter is blocked, 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.
Application of hydraulic boarding bridges: Hydraulic boarding bridges can be widely used in docks, platforms, warehouses, etc. according to user needs. Special designs can be made in terms of external dimensions, load, etc. The fixed boarding bridge is installed on the side of the cargo platform, flush with the ground and side of the cargo platform. The bridge deck of a fixed boarding bridge can tilt up and down, and its outer end can be higher or lower than the plane of the cargo platform, making it equal to the height of the carriage. There is a flip board at the top of the bridge, which automatically attaches to the edge of the carriage, ensuring a smooth passage between the cargo platform and the carriage.
The length of the electric hydraulic boarding bridge is generally about 10 meters, and 11300m for 10 tons. It is very suitable for placement on the ground in open spaces.
Rubin.Monthly maintenance of hydraulic boarding bridges: check for wear on rollers, intermediate shafts and bearings, cylinder pins and bearings, boom hinge shafts and bearings, etc; The oil quality and level of hydraulic oil; The hydraulic boarding bridge should be raised throughout the entire process and at this position, the hydraulic surface should be 40 to 50 millimeters higher than the bottom of the box. The hydraulic oil is darkened, sticky, or has foreign objects such as gravel. If found, it should be replaced in a timely manner; Add some oil to each part to extend the service life of the bearing. The hydraulic boarding bridge has a wide range of uses. Doing the above points well not only ensures your personal safety but also extends the service life of the equipment, making the boarding bridge better serve you.
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, 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.
