How can the hydraulic landing platform achieve emergency descent     When using the hydraulic landing platform, it is sometimes necessary to use an emergency descent, then how to perform an emergency descent?   In order to ensure that the wires are correct, adjust the rotation consistency of the two hydraulic presses. The hydraulic docking bridge is a special auxiliary equipment for fast loading and unloading of goods. Its height adjustment function enables a bridge between the truck and the cargo platform of the warehouse. The forklift and other handling vehicles can directly drive into the truck for bulk loading and unloading through it. Called the loading and unloading platform. The boarding bridge is used for bridge equipment between forklifts and trucks to facilitate loading and unloading of goods. Maximum dynamic load: 6T, maximum static load: 6T, maximum width: 2M, maximum length: 4M. There are many categories, generally divided into mobile docking bridges and fixed docking bridges. Conventional: solid tires with a length of 11M and a width of 2.1M. platform is a kind of lifting cage machinery that vertically transports people or objects. It also refers to the equipment for vertical transportation in logistics systems such as factories and automatic warehouses. The lifting cage platform is often equipped with a variety of flat transportation equipment as a connecting device for conveyor lines of different heights. It is generally driven by hydraulic pressure, so it is called hydraulic lifting platform. In addition to transporting goods at different heights, it is widely used in high-altitude installation and maintenance operations. When the power supply is normal, the construction lift control switch is connected to the platform on the top of the cage for unmanned operation and trial operation. The control switch enables the cage to run several times above and below the chassis. The cage runs smoothly without abnormal noise. At the same time, further check the contact between the guide wheel and the gear, test the normal working load, and perform the above-mentioned operation methods, and further check the motor and the heating of the motor. After all conditions are normal, normal installation and operation are allowed. For the newly installed lifting platform, a static load test of 25% overload for 10 minutes should be carried out to check the rigidity of the cage main beam and the positioning of the guide wheels, and find out the problems that should be solved in time. After the components of the hoisting machinery are installed in place, the relative positions of the components and the length of the stroke switch arm should be adjusted at the same time, and the operation test in the cage can be carried out after adjusting the lower gap.   First make sure that the host is turned off, and then remove the inspection cover connecting the motor and the engine. In the connection hole of the unit coupling, the brake at the tail of the hydraulic machine must be opened by hand at the same time, and the preparation for the second pass, such as the second test piece, will raise the cage about 1 meter. At the same time, check the rising of the cage on the guide rail frame, adjust the position of each roller at any time, make the position of the cage gear and rack accurate, and the operation is balanced, and the contact between each roller and the column tube of the guide frame is uniform without collision. Then gently pull out the door handle by hand to slowly lower the cage, repeat the above operation, and confirm that the operation can run before the mechanical drive test.
