Proof chain hoists maintenance skills

Proof chain hoists as a variety of flammable and explosive environments more specific proof of a lifting tool, its daily maintenance and maintenance are particularly important:
1), the proof  chain block   and driving after use, should pay attention to clean hoists and monorail car explosion dust on some miscellaneous debris, and promptly coated with anti-rust oil, stored in a dry place to prevent rust and corrosion from moisture .


2), the daily checks and more should pay attention to maintenance, maintenance and repair should be familiar with chain hoists and driving agency personnel, non-performance of the machine do not understand the principle of free disassembly. Cleaned with kerosene or other media-proof chain hoists and other mechanical parts, gears and bearings in the rotation or friction parts, filling grease lubrication.
3), the assembly, the proof  manual hoist  lifting around sprocket roller bearings, can adhere to the butter has been pressed lifting sprocket mounted on the inner ring of the bearing journal, and then into the wall of the bearing outer ring inside.
4), proof chain hoists brake friction surfaces must be kept clean. Brake parts should be inspected regularly to prevent brake failure occurred weights from falling accidents.
5), the installation brake parts, pay attention with the pawl ratchet pawls engage alveolar good spring pawl control should be flexible and reliable, installed after the chain started, bracelet wheel clockwise, it will be a ratchet, pressed on the brake friction plate seat,wire rope winch counterclockwise rotation bracelet wheel, ratchet gap should be left between the friction plate.
6), and explosion-proof chain hoists TROLLEYS (small car) After cleaning and maintenance after the load test should be carried out and glide down experiments confirmed working, reliable braking before delivery.
