Crane & Rigging Failures

How much time have you got to get out of the way?

When the lifting attachments fails or the crane tips

over, there is no time to move out of the way.

Usually it happen when your looking the other way.

Jib or Boom & Fly Jib


56/184

57

Boom Stops

Boom stops are telescoping,

shock absorbing, or hydraulic-type safety devices designed

and installed in a manner to

stop or shut off power to the

boom controls. The purpose ofthe boom stops is to prevent

the boom from being raised to

a point where the center of

gravity is shifted to the rear of

the crane causing the boom to

fall backwards over the crane


57/184

58

Jib Angle Indicator Jib Angle Indicators are

required to indicate the angleof the boom tip from the basesection on a horizontal plane.They may be either mechanical(activated by gravity) or

electronic, with a displayreadout in the cab. Accuratereadout of boom angledetermines load capacity andworking radius.
