What are the Different Types of Mobile Cranes?
Anyone who has ever walked past a construction site has
seen all sorts of cranes working away. They’ve seen tower cranes dominate the
site skyline. In its tall shadow, an all-terrain mobile lifter navigates sandy
rises and muddy ditches with ease. Curious now, we can’t help wondering what
other crane types are either driving on a public roadway or huffing their way
around a dirty work site.
Determined By Chassis Differences
There are at least two chassis profiles that come to mind
when looking at different crane types. First off, there’s the lower half of the
lifter. A basic crane truck looks a lot like a regular flatbed vehicle,
although it might feature an extra set of wheels. However, there’s a crane mounted
on that flatbed. All the same, when its boom is secured, crane trucks can drive
on a public highway. That’s something crawler cranes can’t do, nor can their
rough-terrain cousins. Crawlers are equipped with high-traction tracks, just
like a battlefield tank, so they can drive across all kinds of rough soil and
sand. Similarly, rough-terrain mobile cranes utilize multiple axles and huge,
knobby wheels. Last of all, all-terrain mobile lifters also drive easily across
uneven ground, but they can quickly switch gears and rumble slowly along public
Checking Out the Boom Differences
After a mobile crane arrives on-site, its independent
brakes are locked, then the equipment is configured so that it’s ready for
work. Outriggers come out from all sides, if fitted, to stabilize the vehicle.
There are marked differences between those lifting arms, though. Knuckle booms
add articulating versatility to a lift. For larger cranes, rigid booms
telescope their solid or lattice-type arms, but they only ever stretch as far
as the vehicles’ loading chart permits. Smaller truck mounted cranes come with
or without turntables, then there are longer flatbed vehicles, which use their
extra storage space for transporting felled trees.
Considering their many shapes and features, it’s important that the right crane is selected for the right job. Just like selecting the proper tool for a difficult piece of mechanical disassembly work, the hiring procedure relies on previous knowledge. The client supplies that information, then an informed decision is made by the two parties. It’s not like that customer can just point out a crane on the parking lot, after all. A best foot forward approach involves a contractor-hire service rapport. The role of the mobile lifter is then determined so that the client comes away with the right hoisting vehicle, be it a site crawler or a road cruising crane truck.
