Budgit Air Chain Hoist 500 lbs

Warning: This maintenance check requires trained personnel with PPE!

Operate the hoist, with no load, and check for visual signs or abnormal noises which could indicate a potential problem

Chain for lubricant, wear, damaged links or foreign material

Hooks for damage, cracks, twist, latch engagement and latch operation

Any deficiencies found during the inspection

Sign off on the hoist maintenance

Warning: This maintenance check requires trained personnel with PPE!

Hook free from deformations or cracks

Measure the degree of twist from the plane of the unbent hook

Hook opening within acceptable limits

Other load-sustaining components of the hoist free from damage

Latch operates properly with sufficient spring pressure

Sign off on the hook maintenance

Chain should feed smoothly into and away from the hoist or hook block (500, 600 and 1000#, 226, 272 and 453 Kg. units). If chain binds, jumps or is noisy, first clean and lubricate it (see below).; If trouble persists, inspect chain and mating parts for wear, distortion or other damage.

First clean chain with a non-caustic/non-acid type solvent and make a link by link inspection for nicks, gouges, twisted links, weld spatter, corrosion pits, sitriations (minute parallel lines), cracks in weld areas, wear and stretching.; Chain with any one of these defects must be replaced.

Slack the portion of the chain that normally passes over the lift wheel.

Examine the interlink area for the point of maximum wear.; Measure and record the stock diameter at this point of the link.; Then measure stock diameter in the same area on a link that does not pass over the liftwheel (use the link adjacent to the loose end link for this purpose).; Compare these two measurements. If the stock diameter of the worn link is 0.010 inches (0.254 mm.), or more, less than the stock diameter of the unworn link, the chain must be replaced.

On the 500, 600 and 1000# (226, 272 and 453 Kg.) units, repeat this examination of the chain that passes through the hook block.

Also check chain for stretch using a vernier caliper. Select an unused, unstretched section of chain (usually at the loose end) and measure and record the length over 11 chain links (pitches).; Measure and record the same length on a worn section of chain.

Obtain the amount of stretch and wear by subtracting the measurement of the unworn section from the measurement of the worn section.; If the result (amount of stretch and wear) is greater than 0.145 inch (3.7 mm.), the chain must be replaced.

Warning: This maintenance check requires trained personnel with PPE!

Note: These are visual inspections by an appointed person who records apparent external conditions to provide a basis for continuing evaluation.

External evidence of loose screws.

External evidence of worn, corroded, cracked or distorted hook block, gears, bearings, chain stop and hook retainer.

External evidence of damage or excessive wear of the liftwheel or sheave (double reeved unit).

Check chain guide for wear or burring where the chain enters the hoist.

External evidence of excessive wear of brake parts.

Check the control station levers to make sure they operate freely and spring back when released.

Check air supply hose and control hose for kinks, cuts, leaks and damage.

Once a year, remove the air motor and check the condition of the bearings, rotor for possible rubbing on the body or end plates, free movement of the blades in rotor slots, seals and shims.; Replace worn or damaged parts.; If the motor appears to be in good condition, do not service other than lubricating well with light machine oil.

Once a year, disassemble the pendant throttle control and check the condition of the springs, valves and levers.; Replace worn or damaged parts.; If the parts appear to be in good condition, do not service other than lubricating well with light machine oil.

Once a year, disassemble the control valve assembly and check the condition of the pistons, springs, spring seats, gasket, O-rings, valve bolts, air fittings and muffler.; Replace worn or damaged parts.; If the parts appear to be in good condition, do not service other than lubricating them with light machine oil.;
