C-Clamp Question

Make sure the person whose bright idea this was is standing under the motor when you lift it.

With him out of the way you might evolve a better method.

As it is the motor eye bolt is made to lift the motor, as long as it is properly installed and it is an eye bolt of the right weight bearring category. A cheap mild steel eyebolt will fail. The motor maker will tell you what to use.

the eye bolt lifts at the center of gravity, so it is not unbalanced unless you have added weight to one end. We ned more information about what you are doing to be really helpful

There are two styles of eye-bolt. From memory, eye-bolts with a "shoulder", like the Greek letter omega where the thread points downwards, are more suitable for a lift where a limited amount of load may be applied off the axis of the bolt, subject to a review of the manufacturer's details. Eye-bolts without a shoulder are only suitable for an axial lift.

Try reviewing the manufacturer's information for the equipment to be lifted as a guide for the correct lifting arrangement to be used.

v r going to design a fixture to lift two motors using scissor lift...... one motor is of wt 150 kg which will b lifted and turn to 90deg to fix it...... this motor consist of gearbox and rope drum...this will make the motor unbalance but the eye bolt on the gearbox will b used to lift it bcoz the centre of gravity fall on that....... & the another one is 300kg which will b lifted and to turn 180deg to fix in the required position...... but this motor doesn't have any extra arrangement........the reqd height to b lift is 2m.......if v use the c-clamp to tight the motor for support at the both ends the fins of motor will b damaged or not????

It seems you have been asking these questions before.

If you use a scissor lift from below what is the function of the eyebolt?

if v use the c-clamp to tight the motor for support at the both ends the fins of motor will b damaged or not????

Can you not describe what you wish to do? fins are thin and they taper and they are not structural elements. Thus any use to support motors of this size does involve some degree of risk because the fins may break or the c-clamp will slide off.

do yu have any idea what this whole thing is being used for?

Riggers or maintenance personnel typically will fasten additional lines, chains, straps etc, used to maneuver the slung motor or gear motor, by fastening them mechanically as with threaded bolts to available points on the load, such as mounting holes. Clamps are never used for this purpose, and these additional lines are never used to share the load, only to aid in maneuvering or stabilizing it.

Please more details to help you.

Nothing beats a good old sling made of nylon, or a snatch strap as they are called. Use two or three to facilitate you needs. Even use a net if you do not want any damage. Remember, there is more than one way to skin a cat.

C-clamps are not designed and should never be used for lifting. Use slings and a come-along to balance the load. When rigging use only components that are designed for lifting.

Many winches for an example say they will pull so many lbs or tons but do not use for a suspended load.

Hire an experienced rigger.

dai kamesh c clamp will not damage the motor fins bcoz those fins are made up of same material of motor housing. but using c clamp with some cushion lining can help in safe gaurd the motor
