VThe boarding bridge is a typical modern pallet loading and unloading channel， which includes a high loading and unloading platform， a height adjustment plate that connects the platform to the transport vehicle through a floating bridge， and forklifts or manual transfer vehicles entering and exiting the transport vehicle. e. Mainly used for loading and unloading goods in logistics， postal and telecommunications， transportation， industry and mining， but the height of the carriages is different. There is always a certain height difference or gap between the transportation vehicle and the loading and unloading platform. The transfer forklift can quickly enter and exit the transport vehicle for loading and unloading. It is the starting and ending point of the enterprises logistics chain， and a loading and unloading channel for rapid turnover of products and goods. Use boarding bridges to provide reliable connections. The step is to press the lifting handle to raise the boarding bridge above the bottom of the carriage.
LWelcome calls Timely increase phase failure protection and emergency stop devices to improve the safety of the elevator.
oRWhen using the boarding bridge for loading and unloading， load and unload according to the rated load， and do not be overweight. If overweight occurs， it will make the hydraulic system struggle during the lifting process， and even cause deformation of the hydraulic cylinder body， resulting in gaps and oil leakage outward. This requires finding a professional manufacturer for maintenance， such as Shanghai Niuli Machinery. If the deformation is severe， the only option is to replace it with a new one.
Main support: using irregular steel pipes.
When using the shaft， keep the surface of the workbench stable and firm， and the fixed chain must be firmly fixed to the vehicle. The speed during transportation is /hour.
High quality and low priceaBecause there are various types of boarding bridges， there are also many manufacturers of boarding bridges in China. The following are the mechanical equipment hydraulic boarding bridges and fixed fixed boarding bridges. We look forward to providing some assistance to everyone and further mastering hydraulic boarding bridges; Hydraulic boarding bridge” This word is not unfamiliar anymore. If you have to， you can understand which boarding bridge is more suitable for you. Hydraulic boarding bridges， and hydraulic lifting platforms are now common warehouse handling hydraulic tools and machinery equipment. Hydraulic boarding bridges are an industrial equipment that helps cars conveniently load and unload goods. Hydraulic boarding bridges are divided into two types， portable and mobile， which can meet the working requirements of many mobile places， During the entire process of work， it is inevitable to encounter some common faults. Below， lets analyze the common phenomenon of boarding bridges for everyone& mdash; No lifting.
WThe fundamental load， literally， refers to the self weight load of the metal structure， organization， power， and electrical equipment of the lifting channel itself， as well as the lifting load of the lifting mass of the lifting channel. It also includes the impact load that occurs when operating on uneven roads， as well as the horizontal load caused by organizational braking. Can achieve different application effects. The fixed hydraulic boarding bridge is designed based on the equipment environment of the elevator. The fixed hydraulic boarding bridge can be used in conjunction with its own application requirements， and appropriate equipment can be selected to achieve excellent application effects. It is a specialized auxiliary equipment for completing the rapid loading and unloading of goods. Horizontal load problems are often encountered in mobile lifting channels and vehicular lifting channels. How do we understand the additional load on fixed hydraulic boarding bridges? The additional load refers to the load that the lifting channel is subjected to under normal operating conditions under non recurring actions.
Before loading， unloading， and transporting goods， the height of the adjustment plate on the boarding bridge should be adjusted to ensure a smooth overlap with the rear panel of the car. The iron chain on the boarding bridge should be firmly tied to the car.
