Description

Rieker's rugged ALL-Weather Mechanical Boom Angle Indicators are not affected by outdoor elements. These instruments are made tough and will not rust, freeze, or otherwise "hang up" like old fashioned pendulum style boom angle indicators.

Like all of our instruments, each boom angle indicator is properly damped for smooth reliable readings. Designed for easy mounting with two screws for quick and efficient retro-fitting in the field.

4120 Specification Brochure (PDF)

 

*Available in a highly visible backlit model for increased safety - complies with National Fire Protection Association 1901 Standards for Automotive Fire Apparatus.

Please note:  A boom angle indicator is a quick reference for the operator. The capacities that are listed on the crane load charts are also based on and vary with the boom angle of the crane. However, do NOT rely on the boom angle indicator for radius accuracy especially when the lift exceeds 75 percent of the rated capacity. Use the radius measurement to determine the capacity of the crane from the load charts and to avoid any possibility of error.
