Frame Stress Considerations in Mounting Utility Man Lifts and Derricks

Many failures, both major and minor, occur to utility derrick and aerial basket trucks and can be traced directly to the stresses imposed on the truck chassis frame.

Some of these stresses will be reviewed by the user with the hope that it will provoke enough attention to the subject so that an adequate standard mounting procedure will be developed and accepted within the utility industry. On the other hand, the long range solution in some cases may be the design of a specific frame configuration to resist these stresses.
