7.2.5.
7.3. 7.3.1.
Confirm that the load does not exceed the Safe Working Load of the hoist. Ensure that slings/chains/ropes around the load are adequate and in good condition and that the load is directly below block. LIFTING LOAD Pull the load chain (1) in fig.1 down to raise the load. Attach slings/chains/ropes to chain block load hook and ensure safety bar is closed. Make sure load is vertical (i.e. not pulling at an angle). Start to raise the load by pulling the chain (1). Check that the load is level, with no possibility of the load tilting and/or slipping from its restraints. If necessary lower load and re-adjust slings to obtain a safe, level lift. Stop lifting at approximately 100mm to check that brake will hold load. Continue to raise load to required height in a slow and controlled manner. DO NOT raise so far that load hook comes into contact with the chain block. LOWERING LOAD Pull down on chain (7), the load will be lowered. (If there isn’t a load on the bottom hook (6) it will still move up and down, this is normal operation).
8. MAINTENANCE
8.1. LUBRICATION
8.1.1. Check daily for any signs of rust or corrosion. Without a load check for signs of rust that are visible and clean as needed.
NOTE: The chain block MUST be kept clean and dry and must be maintained in accordance with these instructions.
8.1.2. After use, clean off the dirt on the chain block and keep it in a dry place.
8
DO NOT use motor oil to lubricate the equipment. Lubricate the load chain and hook shanks regularly using lithium grease.
8.1.3. Chain wear in the link points needs to be avoided by lubricating the chain at regular intervals tailored to usage. When lubricating the
chain, also check its ware status.
8.2. DAILY INSPECTION
WARNING! Procedures not specifically explained in this manual must be performed only by a qualified technician.
8.2.1. Perform the procedures in this section BEFORE INITIAL USE and DAILY. Inspection is needed more often for heavily used hoists.
8.2.2. Check operating mechanisms for proper operation, proper adjustment, and unusual sounds.
8.3. QUARTERLY
8.3.1. Quarterly (every 3 months), clean off load chain, then lubricate load chain links with lithium grease. Apply grease to inner surfaces of
load chain, where the links rub against each other.
8.3.2. Repair or replacement of hoist components must be performed only by a qualified technician using only identical replacement parts
with the same rating.
8.4. FREQUENT BRAKING SYSTEM INSPECTION
8.4.1. The braking system must automatically stop and hold up to the rated load if the hand chain is released.
8.5. FREQUENT HOOK INSPECTION
8.5.1. Distortion, such as bending, twisting, or increased throat opening.
8.5.2. Wear.
8.5.3. Cracks, nicks, or gouges.
8.5.4. Latch engagement (if equipped).
8.5.5. Damaged or malfunctioning latch (if provided).
8.5.6. Hook attachment and securing means.
8.6. FREQUENT HOIST LOAD CHAIN INSPECTION
8.6.1. Test the hoist under load in lifting and lowering directions and observe the operation of the chain and sprockets. The chain should feed
smoothly into and away from the sprockets.
8.6.2. If the chain binds, jumps, or is noisy, first see that it is clean and properly lubricated. If the trouble persists, inspect the chain and
mating parts for wear, distortion, or other damage. Examine visually for gouges, nicks, weld spatter, corrosion, and distorted links.
Slacken the chain and move the adjacent links to one side to inspect for wear at the contact points. If wear is observed or if stretching
is suspected, the chain should be measured as follows:
I) Select an unworn, un-stretched length of the chain (e.g., at the slack end).
II) Suspend the chain vertically under tension and, using a calliper-type gauge, carefully measure the outside length of any convenient
number of links approximately 12″ to 24″ overall.
III) Carefully measure the same number of links in the used sections and calculate the percentage increase in length.
IV) If the used chain is 2.5% longer than the unused chain, replace the chain.
Check rope or load chain reeving.
WARNING! To prevent serious injury from hoist failure: DO NOT use damaged equipment. If any defect or damage is noted, repair the
problem before further use.
8.7. MONTHLY INSPECTION
8.7.1. A qualified technician should perform the procedures in this section AT LEAST EVERY 3 Months. Inspection is needed more often for
heavily used hoists. Remove or open access covers to allow inspection of components.
8.7.2. First, follow all Frequent Inspection procedures. Additionally:
8.7.3. Check fasteners for evidence of loosening.
8.7.4. Check load blocks, suspension housings, hand chain wheels, chain attachments, clevises, yokes, suspension bolts, shafts, gears,
bearings, pins, rollers, and locking and clamping devices for evidence of wear, corrosion, cracks, and distortion.
8.7.5. Check hook retaining nuts or collars, and pins, welds, or rivets used to secure the retaining members for evidence of damage.
8.7.6. Check load sprockets, idler sprockets, drums, and sheaves for evidence of damage and wear.
8.7.7. Check the brake mechanism for evidence of worn, glazed, or oil contaminated friction disks; worn pawls, cams, or ratchets; and
corroded, stretched, or broken pawl springs.
8.7.8. Check supporting structure or trolley, if used, for evidence of damage.
8.7.9. Check warning label for legibility and replacement.
8.7.10. Check end connections of wire ropes or load chains for evidence of wear, corrosion, cracks, damage, and distortion.
