Boom Trucks

Flexible, reliable, and able to travel at highway speeds, boom trucks are great for lighter lifting. Comprised of a boom mounted on the top of a truck bed, boom trucks can easily navigate a job site. Boom trucks are also commonly known as truck mounted cranes (TMC’s).

The difference between a boom truck and a crane? The boom truck does not have a counterweight. Booms range from 60 to 142 feet, with a lifting capacity up to 40 tons. The further the boom (stick) is extended the less its lifting capability becomes.

Features of the Terex brand include independent outrigger controls for stability and control on rough terrains. In addition, exceptional winch line control allows retracting and extending right down to the inch.

Truck Cranes

Due to their adjustable height and highway mobility, telescopic and articulating (knuckle boom) truck cranes are a great addition to any fleet. For example, these cranes are a common sight in ports. They are available with sheave heights ranging from 80 to 207 feet and load ratings from 18 to 45 tons.

With their line of truck cranes, Terex offers details like corrosion-protected connectors to prevent downtime. Terex cabs are made to ensure operators are comfortable throughout a long lasting project.

Rough Terrain Cranes

As the name says, rough terrain cranes are used to navigate rough terrains and unimproved job sites. They can also maneuver easily through confined areas with tight clearance, making them great for petrochemical facilities.

Also known as "RT" cranes or "off-road" cranes, they typically have a hydraulic boom, four tires and two axles. Most have four-wheel drive and all-wheel steering, increasing maneuverability for off-road operations.

Typical capacity ranges from 30 to 130 tons, with boom lengths between 80 and 140 feet. Larger RT cranes have replaced the smaller crawler crane as the off-road crane of choice.

The steel used to make Terex brand cranes are built to withstand extreme temperatures, while the axles and superstructures can handle mud, snow and extreme terrains. Cabins can also be fitted to include heating and air conditioning.

Crawler Cranes

Crawler cranes, also referred to as lattice boom crawler cranes, are the largest of the cranes. Though these tank-like cranes have to be assembled on-site, their height and size allow for the handling and transporting of loads that other cranes can’t support. They are also usually in operation for a long time.

The crawler's capacity ranges from 40 to 2,000 tons, with a reach up to 700 feet and 500-foot radius. With the low transport height on the crawler's undercarriage, they can be operated on rocky, uneven ground

Terex’s cranes utilize a module system, allowing for a variety of configurations to best fit your project. This system also allows for add-ons including jibs, vessel lifts and windmill kits. Most manufacturers offer multi-functional jib systems that increase maneuverability and reach.

All Terrain Cranes

Combining the features of truck and rough terrain cranes, all terrain cranes can travel on most off-road surfaces. These mobile cranes can also travel at high speeds on public roads and highways. On rough terrain job sites, they use all-wheel and crab steering to maneuver through tight spaces. They typically feature between 2-9 axles and can lift loads up to 1,200 tons.

The cranes under Terex’s All-Terrain Explorer series come with a variety of jibs, including swing away, light-fixed and luffing fly. All components are painted separately to provide an added protection against rust.
