lever hoist wire rope hoist for construction equipment
Also known as fairy gourd, pounds do not drop, manual hoist, is a simple to use, easy to carry the manual lifting, also known as "chain hoist" or "down the chain." It is suitable for short distance lifting small equipment and cargo, the weight is generally not more than 100T. Chain hoists shell material is high-quality steel, extremely resistant, high safety performance. When chain hoists lifting weights upward, hands and pulled clockwise chains, bracelets wheel rotates counterclockwise when pulling hands to pull the chain down the stopper with separate brakes, ratchet pawl still under the effect of the five tooth long axis lifting sprocket drive runs in the opposite direction, so that the weight steady decline.
HS series chain hoists used in structural design and performance has five characteristics:
1. compliance with international standards, safe and reliable, durable.
2. Good performance and easy maintenance.
3. toughness, small size, light weight, easy to carry.
4. The hand-pull small, high mechanical strength.
5. The advanced compact structure, beautiful appearance.
6. areas without power lifting goods.
7. powerful features.
Instructions for use
1. after use should be cleaned and coated with anti-rust gourd oil, stored in a dry place to prevent rusting chain hoists moisture and corrosion.
Chain hoists
2. Maintenance and service should be more familiar with the hoist mechanism were conducted with kerosene hoist parts, gears and bearings in part, plus grease lubrication, to prevent those who do not understand this principle of free entry machine performance.
3. After cleaning and maintenance hoist, load test should be carried out to confirm working, reliable braking can be delivered.
4. The brake friction surfaces must be kept clean. Brake part should be inspected regularly to prevent brake failure, the occurrence of the phenomenon of weight from falling.
5. around the sprocket chain hoists lifting roller bearings can be used in the butter has adhered to the pressure mounted on the lifting sprocket journal bearing inner ring, and then into the wall of the bearing outer ring.
6. The chain hoists when installing brake device section, pay attention to the ratchet and pawl claw portion engages alveolar good control of the pawl spring should be flexible and reliable, after installation to get started sprocket wheel is rotated clockwise bracelet, it will ratchet , brake friction plate is pressed against the seat, wheel counterclockwise rotation bracelets, and the friction between the ratchet pieces should be no gaps.
7. In order to maintain and easy removal, hand chain wherein a chain line opening (not allowed welded).
8. In the refueling process and the use of chain hoists, surface friction braking device must be kept clean and regularly check whether the braking to prevent brake failure caused by heavy objects from falling
