What is a boom truck?
Boom trucks usually have a rotating telescopic-boom crane mounted on a commercial truck chassis. The configuration allows for ease of transport of lifting equipment to job sites and allows the boom truck to maximize utilization.
These are different from truck cranes, which typically mount the crane upon a specially designed carrier.
The truck chassis typically have a flatbed body upon which the boom crane is mounted. The operator controls the crane either inside an operator cab or, if there is no cab, on the ground using controls mounted on the truck and connected to the crane.
These cranes do not use counterweights, so their lift capacity is lower than other types of cranes. Many will have outriggers to help stabilize the truck while the crane is lifting and placing loads.
Some boom trucks have aerial work platforms rather than lifting gear.
