Protection device KOIO electric chain hoist
The general has multiple protection device KOIO electric chain hoist, ensure the personnel and the work safety protection device, but also should have some basic requirements.
1 is to prevent the hazard function, suitable for KOIO electric chain hoist operating conditions, does not interfere with the production and operation.
2 installation is firm, reliable performance, and have sufficient strength and rigidity, accurate action, stable performance.
3 durable, does not affect the hoist adjustment, repair, lubrication and inspection etc..
4 protective device itself should not cause harm to the operator.
Before the KOIO electric chain hoist using the inspection work:
KOIO electric chain hoist before use, simple security check is very necessary, avoid abnormal problems in some parts, good risk prevention in advance.
Button to control the direction and brake, 1 operating handle limit device is sensitive and accurate.
2 wire rope defects, good lubrication, neat.
3 motor and reducer rotating no abnormal sound.
4.KOIO electric chain hoist track and people walking areas without obstacles.
5 hook and pulley can flexibly rotate.
Note KOIO electric chain hoist installation:
KOIO electric chain hoist installation is a very important work, not only to do the preparation before installation, should also pay attention to matters need attention to specific installation.
A, KOIO electric chain hoist to ensure that two ends run to track without derailment or prevent collision damage the body, should set the elastic buffer at the both ends of the track.
B, KOIO electric chain hoist installation, should check the wire rope is fixed with a plug block has loose.
C, track or the connecting frame should be set on the ground wire, metal wire grounding by φ 4- φ 5mm bare copper wire or a section of not less than 25mm ²
D, electrical device all the power circuit, control circuit to ground resistance should not be less than 10000 ohms per volt voltage.
Comprehensive examination of KOIO electric chain hoist is installed:
Electric hoist after installation need to conduct a comprehensive safety inspection, it is necessary from a security perspective is the:
Type of current and voltage, 1 KOIO electric chain hoist electrical device is suitable for the installation site.
2, electrical wiring connection is valid and reliable.
3, limiting device. The action is right or not, flexible, reliable.
4, all the lubricating parts is respectively to add the lubricating oil.
5, the wheel and rail joint is reliable.
6, the selection of power supply cable must ensure the hoist motor input power supply voltage is not lower than the rated voltage.
