  • Overloading for length, size, or angle of boom
  • Improper calculation of load weight. Remember to include the weight of all rigging
  • Boom too high
  • Two blocking
  • Attempting side pulls
  • Swinging load and not paying attention to the side load on boom
  • Load hitting boom
  • Walking or turning too fast, causing load to swing and twist boom
  • Failure to use tagline or other control on a load
  • Not using outrigger, or outriggers improperly shored
  • Not enough counterweight, tipping the cab house and chassis
  • Using boom with twisted members or braces. Makeshift repairs
