The boom lift dimensions that decide a job are not the working height. They are the stowed width, from about 4 feet on a 30 foot electric machine to over 8 feet on a 125 foot diesel, the stowed length, the tail swing behind the turntable, and the weight, which runs from roughly 5,000 pounds to well past 40,000. Those four settle whether the machine ever reaches the work.
Stowed width by class
Electric articulating machines to 45 feet are commonly 4 to 5 feet 6 inches wide, which is what lets them through a double door and along a corridor. Rough terrain machines from 60 feet upward run 7 to 8 feet on four wheel drive axles, and the tallest telescopic units are wider again. Width, not height, is the access limit indoors.
Length, and the tail that swings behind you
A stowed 60 foot boom is roughly 25 to 30 feet long, which decides whether it turns a corner in a yard or a car park. Then there is tail swing: on most machines the counterweight sweeps out behind the turntable as it slews. Leave that clearance or the machine hits the wall it is working on.
Weight is a dimension too
An electric 30 foot machine is near 5,000 pounds, a 60 foot rough terrain unit 20,000 to 25,000, and a 125 foot machine well beyond 40,000. Check that figure against any slab, deck, basement lid, culvert or car park level the machine must cross, and check it before the delivery truck is booked rather than after.
Doorways, ramps and the height on the trailer
Indoors the numbers to compare are the machine's stowed height against the door opening, and its gradeability against the ramp. On the road the loaded height on a trailer decides which bridges the route can use. Give the yard the access details and let them pick, since a machine that will not fit is still a paid delivery.
Questions people ask about boom lift dimensions
Will a boom lift fit through a double door?
The narrow electric machines will. Around 4 feet 6 inches wide and 6 feet 6 inches stowed height is common in the 30 to 40 foot classes, which passes most double doors and freight openings. Measure the opening and the turn immediately inside it, because the turn stops more machines than the door does.
What width is a 60 foot boom lift?
Usually 7 to 8 feet across the wheels for a rough terrain machine, with an outrigger or axle spread on some models that is wider again. There are narrow 60 foot machines built for interior work, and yards keep few of them, so ask early if the access is tight.
How much does a boom lift weigh?
From about 5,000 pounds for a small electric to more than 40,000 for the tallest diesel machines. The figure is on the plate on the chassis and the yard will give it on request, and it is the number a structural engineer will want if the lift works over a suspended floor.
Does the platform height include the person?
No. Platform height is the floor of the basket, and working height is conventionally that plus about six feet for a person standing in it. Compare the two carefully when you check whether a machine reaches the work, because the difference is a whole storey on a short lift.
