Ritchie Bros issued this post which great information on the types and uses of mobile cranes. Cranes have instrumental in constructing houses, buildings, cities, and nations. What would take hundreds of people and hours to accomplish, one of these cranes can do in just minutes.
Here are some of the most common types of mobile cranes used on construction sites today:
Hydraulic Truck Cranes
Hydraulic truck cranes can lift thousands of pounds using hydraulics. That rely on forces transmitted through oil pushing the boom pistons in opposite directions.
Hydraulic truck cranes are essential to building major projects like bridges, buildings, airports, roadways, and more.
All Terrain Cranes
All terrain cranes are multi-functional cranes designed to be driven on both smooth paved highways or off-road at speeds up to 40 mph.
They were developed in 1981 by Liebherr out of a need for telescopic cranes in the construction of 3,100 miles of gas pipelines and pumping stations in Siberia.
Typically all-wheel drive, all terrain cranes are powered by one or two engines and feature hydraulically operated winches and a telescopic boom that can reach close to 200 feet and carry up to 130 tons on some models.
Rough Terrain Cranes
Rough terrain cranes are designed to operate specifically off-road on rough terrain thanks to their all-wheel drive capabilities and rubber tires.
Rough terrain cranes are used for pick-and-carry operations like bridge-building and large construction projects where high maneuverability and lifting capacity is needed.
Crawler cranes are a type of tracked mobile crane available with either telescopic or lattice booms. Because they are self-propelled they are able to move around a construction site and perform jobs without much set-up. They are however very expensive to transport from site to site because of their great size and weight.
Crawler crane tracks provide additional stability meaning they can operate without the use of outriggers, though some models do include them.
Carry Deck Cranes
Carry deck cranes are smaller mobile cranes that travel on four wheels and are capable of rotating their boom a full 360-degrees.
An American invention, carry deck cranes are designed to work in confined spaces and can transport the loads they pick up on the small built-in deck around their cab.
