Crane Systems | By Jon Walters | Nov 17, 2016
Does the age of a crane prevent it from having a collision avoidance system installed?
No. The age of a crane has no impact on whether a collision avoidance system can be incorporated, but there is some basic information that should be considered to ensure it is applied correctly.
Confirm the necessary control voltage needed so the collision avoidance system can be matched to the existing control voltage. This ensures major changes will not be needed to existing crane control logic. Magnetek’s collision avoidance systems are designed to operate with control voltages of 12-240 VAC or VDC.
Is it a contractor control, static stepless control or a variable frequency drive? Determining the existing control scheme defines how the output(s) from the collision avoidance system will be incorporated into the existing control logic. Older cranes may be operating with contactor controls, but still permit the installation of collision avoidance systems.
What crane motions will collision avoidance be applied to? Motions may be:
The number of motions, along with any “no fly” zones, will determine the number of collision avoidance systems needed.
The distance at which a collision avoidance system will “trigger” is determined based on the distances and speeds of the traverse motions in accordance with what is deemed safe for a slowdown and stop function.
The above factors will help determine the configuration of a collision avoidance system that can be added to your crane, which, again, may be implemented regardless of crane age.

Options for safe crane operation extend beyond the crane and hoist system. The selection and application of crane control equipment can significantly impact the safe performance of an overhead crane.
