6m 9m 380V Remote Control Heavy Duty Compact Wire Rope Crane CD1 Electric Hoist

Electric hoists are mainly divided into: chain electric hoists, wire rope electric hoists (explosion-proof hoists), anti-corrosion electric hoists, double drum electric hoists, hoists, miniature electric hoists, group crane electric hoists, and multi-functional hoists.
Application areas: lifting, pulling, loading and unloading heavy objects, flip welding of oil tanks, such as the installation and movement of various large and medium-sized concrete, steel structures and mechanical equipment, suitable for construction and installation companies, civil engineering and bridge construction in factories and mines, Machinery and equipment for basic construction projects such as electric power, ships, automobile manufacturing, construction, highways, bridges, metallurgy, mining, slope tunnels, shaft management and protection.
Electric hoists generally have multi-directional protective devices to ensure the safety of personnel and work, but the protective devices should also have some basic requirements.
1. With the function of preventing danger, it is suitable for the operating conditions of the electric hoist, and does not hinder the production and operation.
2. The installation is firm, the performance is reliable, and it has sufficient strength and rigidity, accurate action and stable performance.
3. Durable, does not affect the hoist adjustment, repair, lubrication and inspection, etc.
4. The protective device itself should not cause harm to the operator.
Check the work before using the electric hoist
Before the electric hoist is used, a simple safety inspection is necessary to avoid abnormal problems of some parts and to do danger prevention work in advance.
1. The buttons of the operating handle control the direction, brakes and limiters are sensitive and accurate.
2. The steel wire rope is free of defects, well lubricated and neatly arranged.
3. There is no abnormal sound when the motor and reducer rotate.
4. There are no obstacles in the electric hoist track and personnel walking area.
5. The hook and pulley can rotate flexibly.
Electric hoist installation precautions
The installation of electric hoist is a very important job, not only to do the preparations before installation, but also to pay attention to the matters needing attention in the specific installation.
A. In order to ensure that the electric hoist does not derail when running to both ends of the track or prevent collision and damage to the body, elastic buffers should be installed at both ends of the track.
B. When installing the electric hoist, check whether the plug used to fix the wire rope is loose.
C. A grounding wire should be set on the track or its connected frame. The grounding wire can be a bare copper wire with a diameter of φ4-φ5mm or a metal wire with a cross-section of not less than 25mm².
D. For all power circuits of electrical installations, the resistance to ground of the control circuit shall not be less than 10000Ω per volt working voltage.
Comprehensive inspection of electric hoist after installation
After the electric hoist is installed, a comprehensive safety inspection is required, which is very necessary from a safety point of view:
1. Whether the electrical equipment of the electric hoist is suitable for the current type and working voltage of the installation site.
2. Whether the electrical circuit connection is correct and reliable.
3. Whether the action of the limit device is correct, flexible and reliable.
4. Whether all lubricating parts are filled with lubricating oil separately.
5. Whether the connection between the wheel and the track is reliable.
6. When selecting the power supply cable, it must be ensured that the power supply voltage of the incoming terminal of the hoist motor is not lower than the rated voltage.
