Crosby® Load Binders

Warnings & Application Instructions

Mechanical Advantage

Lever Type Binder = 25 : 1
Ratchet Type Binder = 50 : 1
Example: 100 pounds of effort applied to the binder
results in the following force on the binder.
Lever Type:
2500 (100 lbs. x 25) lbs. of force
Ratchet Type:
5000 (100 lbs. x 50) lbs. of force

Instructions — Lever Type Load Binders

  • Hook load binder to chain so you can operate it while standing on the ground. Position load binder so its handle can be pulled downward to tighten chain. Be aware of ice, snow, rain, oil, etc. that can affect your footing. Make certain your footing
    is secure.
  • The Crosby Group, Inc. specifically recommends AGAINST the use of a handle extender (cheater pipe). If sufficient leverage cannot be obtained using the lever type load binder by itself, a ratchet type binder should be used.
  • If the above recommendation is disregarded and a cheater pipe is used, it must closely fit the handle and must slide down the handle until the handle projections are contacted. The pipe should be secured to the handle, for example, by a pin, so
    that the pipe cannot fly off the handle if you loose control and let go. The increased leverage, by using a cheater pipe, can cause deformation and failure of the chain and load binder
  • • During and after tightening chain, check load binder handle position. Be sure it is in the locked position and that its bottom side touches the chain link.
  • Chain tension may decrease due to load shifting during transport. To be sure the load binder remains in proper position: Secure handle to chain by wrapping the loose end of chain around the
    handle and the tight chain, or tie handle to chain with soft wire.
  • When releasing load binder, remember there is a great deal of energy in the stretched chain. This will cause the load binder handle to move very quickly with great force when it is unlatched. Move handle with caution. It may whip — Keep body clear.
  • Never use a cheater pipe or handle extender to release handle. Use a steel bar and pry under the handle and stay out of the path of handle as it moves upward.
  • If you release the handle by hand, use an open hand under the handle and push upward. Do not close your hand around the handle. Always keep yourself out of the path of the moving handle.

Instructions — Ratchet Load Binders

  • Position ratchet binder so it can be operated from the ground.
  • Make sure your footing is secure.

Maintenance of All Load Binders

  • Routinely check load binders for wear, bending, cracks, nicks, or gouges. If bending or cracks are present — Do not use load binder.
  • Routinely lubricate pivot and swivel points of Lever Binders, and pawl part and screw threads of Ratchet Binders to extend product life and reduce friction wear.


  • Failure to use this load binder properly may result in serious injury or even death to you or others.
  • Do not operate load binder while standing on the load
  • Move handle with caution. It may whip — Keep body clear.
  • Keep yourself out of the path of the moving handle.
  • You must be familiar with state and federal regulations regarding size and number of chain systems required for securing loads on trucks.
  • Always consider the safety of nearby workers as well as yourself when using load binder.
  • While under tension, load binder must not bear against an object, as this will cause side load.
  • Do not throw these instructions away. Keep them close at hand and share them with any others who use this load binder.
