Precautions for Using Construction Hoist Anti-fall Safety Device

• Anti-fall safety devices, whether in use or not, should be inspected and calibrated annually. They can only be used if they are within the validity period of the inspection.
• Users are not allowed to open the lead seal of the anti-fall device without authorization. Once the lead seal is damaged or falls off, the anti-fall device should be re-inspected and calibrated. Otherwise, the user unit will be held responsible for any accidents.
• The warranty period for newly purchased anti-fall devices under normal use is one year.
• The anti-fall device is a safety protection device for construction elevators, and the national standard stipulates that the service life is five years (calculated from the date of manufacture). Otherwise, the anti-fall device should be replaced.
• There is an oil filling hole on the outer shell of the anti-fall safety device in the cage. Add lubricating oil regularly according to the factory technical requirements, and it is strictly forbidden to add lubricating oil into the heat dissipation hole of the outer shell.
• After the anti-fall safety device is installed, be sure to pay attention to the meshing gap between the gear and the rack. If the meshing gap is too small, it may cause meshing interference and generate abnormal vibration and sound. If similar problems occur, they should be adjusted in time.
• The user must not remove the lead seal and adjust the position of the limit switchand the return ring retraction indicator pin of the anti-fall safety device without authorization.
