Urbanization is resulting in less open space, driving greater demand for compact equipment. Boom lifts are no exception with smaller models that can work in tight quarters and that are easily transportable gaining in popularity. There are many boom types to choose from including articulated, telescopic, mast style, towable and compact crawler. Careful consideration should be given during selection, including the work that needs to be done, height requirements, obstacles the boom may need to maneuver up and over, the number of people, tools and materials the platform will need to support and the space in which the boom will need to operate. Selecting a boom has traditionally been manual in nature. If you get it right, you’re off to work. If you get it wrong, you have unnecessary delays and downtime on your hands. New tools such as Building Information Modeling (BIM) allow design engineers to select and place to scale equipment models into 3D environments during project planning.

Articulated Booms Are Great for Confined Spaces

More compact than telescopic booms, articulated booms are ideal for working at height in confined spaces. However, there is more than just working height to consider when selecting an articulated boom. A key feature of an articulated boom is the capability to reach up and over obstacles. This is referred to as maximum horizontal reach, showing how far forward the boom can reach, and clearance height at maximum outreach, which is the height of obstacles that the boom can reach over at the maximum horizontal reach. A difference between articulated booms is whether they have a single or double riser. The riser is the lower boom structure, which may be a single section or two sections, divided by a knuckle. A single riser boom will have a greater stowed length and a greater horizontal reach than the double riser. Booms with a double riser are common in the rental sector as they are more compact when stowed, enabling multiple units to be carried on a truck and have a reduced boom overhang.

Safety & Damage Assessment

When a machine has been involved in an incident, damage to a boom lift may be undetected and can only be identified by a thorough inspection and possibly complete disassembly. For this reason, all inspection and damage assessments must be conducted by a qualified service or engineering person/entity. Damage must be assessed based on the nature of the incident, abuse or misuse and the probable damage that could result. A component failure (e.g structures, tires, control systems, etc.) may cause a potential hazard including, in the case of a MEWP, the platform and its occupants to fall from an elevated position, which could result in death or serious injury. Further inspection and/or disassembly may reveal additional damage to the machine and its component parts. Until the machine has been fully inspected and all damaged machine components are replaced or repaired, the machine must include any inspection or repair documentation to any party taking possession of the machine, for any purpose.
