Safety Instructions For Ratchet Hoists

Operating a Ratchet Hoist can be dangerous if not used properly. Your Hoist has a warning label affixed similar to that shown below. Please take a few moments to familiarize yourself with the warnings it describes.

In addition, please refer to the warn ings displayed on the opposite page as well as the additional warnings described here:

1.

2.

Never use a motor or other mechanical device to lift the load. The Ratchet Hoist is designed to be comfortable for a person to lift using hand power.

Before lifting, inspect the hooks to make certain they are securely attached. Also verify

the safety catch is operating. Periodically inspect the hook and chain to verify that the metal displays no cracking or other signs of potential failure.

Never allow the hoist operator or other personnel to pass underneath a suspended load.

When lifting or lowering, the ratchet lever should be pulled steadily to avoid jerking or tan gling of the chains.

If the ratchet lever should ever seem to require excessive force, check for the following: a)Is the load over the rated capacity of the hoist?

b)Is anything entangled in the load?

c)Are the chains blocked or trapped on something?

OPERATION

5.

Secure the swivel hook which is directly attached to the ratchet body to a structurally sound over head beam or other solid structure which is capable of handling the weight to be lifted. The hoist can be mounted to a beam trolley if the capacity of the trolley system is equal to or greater than the antici pated load.

Position the load directly under the chain hoist. Flip the lever on the ratchet handle to the neutral (“N”) position. This allows the chain to be freely moved through the block by either pulling on the chain or turning the handwheel. Pull enough chain to allow connection of the load hook to the item.

Positioning the hook on the load may require lifting straps or chains if a suitable lifting device is not incorporated on the load (e.g. an eye bolt). Never wrap the hoist’s lifting chain around the load.

Always use a separate set of straps or chains which should then be connected to the load hook. Be sure the load chain is not twisted or entangled in the lifting chain.

Eliminate any slack in the chain between the ratchet body and the load. Switch the lever to the “UP” position. Pull on the ratchet lever with successive strokes and the load will begin to rise. Inspect the load chain and hook position to make sure it will stay properly positioned as the lifting continues.

Continue pulling the ratchet lever back and forth until the load is raised.

Move the truck or pallet you are placing the item on under the raised load. If the Hoist is attached G8709-G8711 Ratchet Hoists

to a travelling trolley system, move the load slowly and carefully, mak ing sure that no one passes beneath the load as it traverses.

When the load is positioned as desired, switch the lever to the “DOWN” position again by crank ing the ratchet lever. The load will go down. Make certain that the lift ing chain is free to travel through the ratchet body and can not get caught on any obstruction.

When the tension on the load chain is off, release the load chain.

Maintain control of the raised load at all times. If traversing the load on a trolley system, be sure the load does not begin to swing back and forth. Never let any portion of the operator’s body, or other personnel, come between the raised load and the floor. Severe crushing injury or death can occur if the load should fall. Always be sure to observe the load limits of your hoist as well as the support structure and any device you are putting the load onto.

MAINTENANCE

1.

2.

Clean any dirt off of the lift and load chains and ratchet block to avoid having any foreign material potentially interfere with the brake and ratchet system.

Periodic lubrication with a light grease on the gears inside the ratchet block will ensure free and smooth operation. Grease can be applied with a scrap piece of wood through the opening in the bottom of the ratchet block.

3.

Generally disassembly of the ratchet block mechanism should never be required. If it should become necessary, this mainte nance should be performed by a skilled service technician who is familiar with these types of lifting devices.

4. If the device is disassembled for servicing, be sure to check the hoist with a light load to be sure the brake mechanism is proper ly holding the lifted load. If it appears okay with a light load, move to a load at its maximum capacity and perform the same check.

-6 Disassembly and improper reassembly of this device can result in the braking or locking mecha nisms not working properly. Loads may not stay suspended and might cause a crushing injury. Always have this device serviced by a qual ified repair technician. Serious injury will result.
