The PIERCE chain hoist is a serious piece of equipment sure to add ease to work in your garage and shop. Now that you have it, you're anxious to put it to use. Make sure you follow all instructions installing your chain hoist to get years of use. Don't forget to register your PIERCE product!
1. Before installation check for the following:
√ Transit damage.
√ External wiring is in good order.
√ The load chain is in good order.
√ All fasteners and joints are tight and secure.
√ The capacity of the lifting unit and bottom block.
Once package has been opened, carefully inspect the hoist frame, hooks, chain, and control station for damage that may have occurred during shipment.
3. Power Supply System:
To insure proper operation, to avoid damage to the hoist and electrical system, and to reduce the risk of electrical shock, or fire, the branch circuit supplying power to the hoist must:
a. Effectively ground the hoist in accordance with the National Electrical Code and other applicable codes. Proper grounding provides a path with the least resistance for the electrical current to travel reducing the risk of electrical shock. The standard power cord is equipped with a three prong plug, used with our 110V, 220V, 240V unit. Make sure that the receptacle opening that receives the longest prong is properly grounded.
b. Be in accordance with the National electrical Code (ANSI/NFPA-70) and applicable, National, State, and local codes.
c. Include a disconnecting means capable of being locked in the open position.
d. Have ample capacity to prevent excessive voltage drop during starting and operation. When determining the size of branch circuit, components and conductors, special consideration should be given to the starting current amps (approximately three times that shown on the hoist identification plate) and the length of the conductors. As a minimum, the system should be rated for 20 amps and the system should have #14 AWG or larger, wiring.
e. Include slow blow type fuses or inverse trip time circuit breakers to permit the hoist to start and accelerate the load.
4. Connection to the electrical supply:
An adequate supply system is required along the total length of travel (where appropriate). The supply voltage and frequency at which the hoist operates, is marked on the motor rating plate. It is imperative to check before connecting the unit that the figures correspond with those of the supply voltage.
5. 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 amount. If you are not sure of the weight the structure can hold, consult a registered engineer and the local building codes.
6. Load Chain:
The chain should feed smoothly into and away from the hoist and hook block (1/2 ton and 1 ton). If the chain binds, jumps or is noisy, first clean and lubricate the chain, if trouble persists inspect the chain and mating parts for wear, distortion, and other damages.
7. Load Chain Lubrication:
Always lubricate load chain weekly or more frequently depending on severity of service. Lubricate load chain with a light coat of lubricate bar and chain oil 10-R (Fiske Bros. Refining Co.) or equal lubricant. Be sure the lubricant reaches the bearing surfaces between the links. Remove the excess oil from the chain.
8. Hook and Eye Suspension Hoists:
The suspension point should be of a correct size to admit the top hook or eye of the hoist and allow it to rest properly on the saddle. It must be adequate to support the the hoist while it is being operated at it's maximum capacity (safe working load).
9. Chain Container:
For installations where the slack chain hanging from the hoist may be objectionable or hazardous, the use of a chain container is recommended.
10. Installation of Standard Chain Container:
a. Remove both bolts from the chain container mounting bracket.
b. Attach the chain container to the bracket.
c. Re-insert the bolts.
11. Test and Operational Checks:
On completion of installation, but before the hoist is put into regular service, the following procedure should be carried out:
1. Record the hoist's Code, Lot, and Serial number from the name plate on the hoist.
2. Check that the hoist is properly installed to either a fixed point or trolley, whichever applies.
3. If hoist is installed on a trolley, ensure that:
The trolley is properly installed on the beam.
The stops for the trolley are correctly positioned and securely installed on the beam.
4. Isolate the power supply
5. Check that all mechanical and electrical joints and connections are tight and secure.
6. Check that all nuts, bolts, and pins (cotter pins) are securely fastened.
7. Confirm proper operation:
Before operating read and become familiar with the owners manual
Before operating check to ensure that the hoist (and trolley) meet the inspection, Testing, and Maintenance requirements of ANSI/ASME B30.16
Before operating check that nothing will interfere with the full range of the hoist's (and trolley's) operation.
8. Switch on the power supply.
9. Run lightly with no load, throughout the full extent of the hoist and check that the operation is smooth at all times.
10. Check the operation of the hoist brake, run under light load and full load conditions.
