SosnoikSecond Incorrect connection of the elevator motor When a coil, coil group, or one phase winding group is connected inversely, it can cause a serious imbalance in the three-phase current and cause the winding to overheat.
For guideway elevators installed outdoors, they are often exposed to rain and sunlight, so special attention should be paid to regular maintenance and inspection to avoid accidents.
Sosnoik.All previous inspections and commissioning have been carried out, and all technical indicators have met the design requirements. When using, it is only necessary to connect the power supply, and there is no need to adjust the hydraulic and electrical systems.
Corrosion prevention measures for the body of aerial work vehicles Attention to small scratches The paint surface of aerial work vehicles often corrodes. In addition to common collisions, scratches, and small rocks on the drive tire, there can also be a paint peeling point that can cause a small rust over time. Because most of these scars are small and easy to ignore. Therefore,SosnoikFixed guide rail lifting cargo elevator, regularly inspect the engine compartment lid and surrounding areas, and once found, go to a professional beauty shop for processing in a timely manner.
.Before connecting the motor to the elevator, the elevator manufacturer should first make the motor shaft keyway perpendicular to the tightening bolt. To ensure uniform stress, but do not tighten them. Then screw on the other two mounting bolts at diagonal positions, and then tighten the four mounting bolts one by one. After that, tighten the tightening bolts. All tightening bolts shall be fixed with a torque wrench according to the indicated fixed torque data, and the use of elevators and lifting platforms shall be checked
The cleanliness of the hydraulic station is an important aspect of the elevator hydraulic station, so it should not be taken lightly. Moreover, from a professional perspective, there are relevant rules and requirements. You should refer to the specification manual, so that you can have a correct understanding and know how to achieve better cleanliness.
Before installing the elevator, confirm whether the motor and the elevator are intact, and strictly check whether the dimensions of each part connecting the motor and the elevator match. Here are the dimensions and fit tolerances of the positioning boss, input shaft, it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation, clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.

The elevator is a kind of elevator equipment composed of a walking mechanism, a hydraulic mechanism, an electric mechanism, and a support mechanism. The hydraulic oil forms a certain pressure by a vane pump, and enters the lower end of the hydraulic cylinder through an oil filter, flameproof electromagnetic directional valve, throttle valve hydraulic control one-way valve, and balance valve. This allows the hydraulic cylinder to move upward and lift heavy objects. The return oil from the upper end of the hydraulic cylinder returns to the tank through the flameproof electromagnetic directional valve, and its rated pressure overflow valve is adjusted. Observe the reading value of the pressure gauge on the pressure gauge.

The purpose of hydraulic lifting platform Users can choose the power mode and configuration according to their own scope of use: power systems include: DC power supply, single-phase or three-phase power supply, diesel engine.
In addition,SosnoikChain guide rail lifting cargo elevator, it is strictly prohibited to use a hammer during installation to prevent excessive axial or radial force from damaging the bearings or gears. Be sure to tighten the mounting bolts before tightening the tension bolts. Before installation clean the anti rust oil on the motor input shaft, positioning boss, and elevator connection parts with gasoline or zinc sodium water. Its purpose is to ensure the tightness of the connection and the flexibility of operation, and to prevent unnecessary wear and tear.
For guideway elevators installed outdoors, they are often exposed to rain and sunlight, and provide safety technical disclosure to installation personnel.
Purpose of manual hydraulic platform: The manual hydraulic transportation platform has novel design, and convenient use. Suitable for loading, unloading, transporting, and stacking barrels in factories, workshops, warehouses, and oil depots. It is particularly suitable for use in chemical and food workshops as a dumping or batching machine. It can also be used to load and unload heavy objects on trucks, stack them, and cooperate with hydraulic drum trucks. It can greatly improve work efficiency and reduce labor intensity. It can also be modified for loading and unloading and lifting heavy objects. It is a new and ideal multi-purpose lowering and unloading machine.
Purpose The hydraulic lift is widely used in various industrial enterprises and production lines such as automobile, container mold manufacturing,SosnoikLifting cargo elevator 1 ton, wood processing, chemical filling, etc., to meet the lifting requirements of different operation heights, and can be equipped with various table forms (such as ball, roller, turntable, steering, tipping, telescoping), and with various ways (separate, explosion-proof), it has the characteristics of stable and accurate lifting, frequent starting, and large load capacity, Effectively solve various lifting and lowering operation difficulties in industrial enterprises, making production operations free. Professional elevator factory has advanced technology, strict testing, more affordable prices, and more preferential treatment. Welcome to consult
Sosnoik.Motor connection error. When the triangular connection motor is mistakenly connected into a star shape, the motor still operates with full load, and the current flowing through the stator winding exceeds the rated current, leading to the motor stopping itself. If the stopping time is slightly longer and the power supply is not cut off, the winding will not only be severely overheated, but also burned. When a star connected motor is mistakenly connected into a triangle, the motor is mistakenly connected into two branches in parallel, both the windings and the iron core will overheat, and in severe cases, the windings will be burned.
Test the goods elevator every day to see if it can operate normally.
Does the cleanliness of the hydraulic station have relevant rules and requirements?
