5. Electric Motor

Unpacking.
After opening the carton, carefully inspect the hoist frame, cords ,hooks, CHAIN and control station for damage that may have occurred during shipment.

Mounting the hoist.
Hang the hoist from its intended support. The structure used to support the hoist must have sufficient strength to withstand several times the load imposed. Suspending the hoist from an inadequate may allow the hoist and to fall and cause injured and/or damage.

Checking for adequate voltage at hoist.
The hoist must be supplied with adequate electrical power for proper operation and to reduce problems that may result from insufficient power(low voltage) . These include:

1. Noisy hoist operation due to brake and/or contact chatter.
2. Heating of the hoist motor and other internal components as well as heating of wires and connectors in the circuit feeding the hoist.
3. Failure of the hoist to lift the load due to motor stalling.
4. Slowing of motors connected to the same circuit.

Checking for others.
After the hoist is suspended from its support and you have made sure the power supply complies with the requirements the hoist is
ready for operation.

Operating Instructions

1. Check if the (emergency) stop switch is pressed. Turn the red stop switch clockwise to engage.
2. An overload is indicated when the hoist speed slows down, it raises the load in a jerky manner or it will not lift the load at all. Also, some clutching noise may be heard if the hoist is loaded beyond rated capacity. If this occurs, immediately release the “up” button to stop the operation of the hoist. At this point, the load should be reduced to the rated capacity. when the excessive load is removed, normal hoist operation is automatically restored.
3. The hoist is not recommended for use in any application where there is a possibility of adding to an already suspended load to the point of overload. Also if the hoist is used at unusual extremes of ambient temperatures, above40 ℃, or below -9℃,changes in lubricant properties may present possibility of damage or injury, and in that conditions the work duty is reduced than normal operating conditions.
4. Hoist operation is controlled by depressing the control station push buttons. Depressing the “up” push button will move the load hook toward the hoist; depressing the “down” push button will move the load hook away from the hoist.
5. The “up” and “down” buttons are momentary type and the hoist will operate in the selected direction as the long as the button is held in the depressed position. Release the push button and the hoist will stop.
6. When preparing to lift a load, be sure that the attachments to the hook are firmly seated in hook saddle. Avoid off center loading of any kind, especially loading on the point of the hook.
7. When lifting, raise the load only enough to clear the floor or support and check to be sure that attachment to the hook and load are firmly seated. Continue lift only after you are assured the load is free of all obstructions.
8. Do not use this hoist out of its work duty.
9. Stand clearing of all loads and avoid moving a load over heads of other heads of other personnel. Warn personnel of your intention to move a load in their area.
10. Do not leave the load suspended in the air unattended.
11. Permit only qualified personnel to operate unit.
12. Do not wrap the load chain around the load and hook on itself as a choker chain.
13. Do not allow a load to bear against the hook latch. The latch is to help maintain the hook in position while the chain is slack before taking up the slack chain.
14. Take up a slack load chain carefully and start load easily to avoid shock and jerking of hoist chain. If there is any evidence of overloading, immediately lower the load and remove the excess load.
15. When the push button is pressed, the machine will stop.

Periodic Inspection

To maintain continuous and satisfactory operation ,a regular inspection procedure must be initiated so that worn or damaged parts can be replaced before they become unsafe, the intervals of inspection must be determined by the individual application and are based upon the type of service to which the hoist will be subjected.

Periodic inspections are to be performed semi-annually and it should include the following:

1. Extemal evidence of loose screws.
2. Extemal evidence of worn , corroded, cracked or distorted hook fixing block, gears, bearings, chain stop ball and hook retainer.
3. Extemal evidence of damage or excessive wear of the lift-wheel. Widening and deepening of pockets may cause chain to lift-up in the pockets and cause binding between lift-wheel and chain guide or between lower sheave and hook block. Check chain guide for wear or burring where the chain enters the hoist .severely worn or damaged parts should be replaced.
4. Extemal evidence of excessive wearing of brake parts. Check the control station push buttons to make sure they operate freely and spring back when released.
5. Check power cord, control cord and control station for damaged insulation.
6. Check the chain pin or dead end pin and chain stop for wear and cracks. Any deficiencies noted must be corrected before the hoist is returned to service.

Hook Inspection
Hook damaged for chemicals, deformations or cracks or that have more than a 10°twist from the plane of the unbent hook or excessive throat opening indicates abuse or overloading of the unit.
Check to make sure that the latch is not damaged or bent and that it operates properly with sufficient spring pressure to keep the latch tightly against the lip of the hook and allow the latch to spring back to the tip when released. If the latch does not operate properly, it should be replaced.

Chain Inspection
Nicks, gouges, twisted links , weld spatter, corrosion pits, striations, cracks in weld areas, wear and stretching. Chain with any one of these defects must be replaced.

Lubricate the chain using 3#calcium-based grease after 200 per cycles. Life of chain is 50000cycles.
Slack the portion of the chain that normally passed 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 lift wheel (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 0.254 mm(or more).
Less than the stock diameter of the unworn link, the chain must be replaced. The chain length is 3 meters and it has 143 Knots.FIG 2.2 is specific dimensions of the chain

Lubrication
The gears are packed at assembly with grease and should not need to be renewed unless the gears have been removed from the housing and the grease is removed.

Bearing.
Rotor bearings are lubricated and require no lubrication. Needle bearings are packed at assembly with grease and should not to be re-lubricated. However, if the housings, lift-wheel or sheave wheel have been decreased, these bearing should be greased using lithium grease.

Load Chain Removal/Installation(FIG3 & FIG4 &FIG5).

1. Remove the chain bag(FIG 3)

2. Remove the hook lock(FIG 4). Depress “up” button and run chain out of the hoist.
3. Jog the “down” push button while pulling on the new chain until the old chain comes out of the hoist.
4. Attach the hook block to the new chain.
5. Remove the chain stop ball from the old chain(FIG 5) and attach it to the new chain by reusing the chain pin.
