In the crane industry, the all-terrain crane is a luxury model of a mobile hydraulic crane. The reputation of this crane is like driving a Range Rover or a Hummer on pavement. All-terrain cranes are considered to be a hybrid between a mobile truck crane and rough terrain crane. One more great quality of this particular equipment is its multi-functional ability to be able to navigate through all kinds of off-road terrain. Among the main selling features of this crane is that it travels equally well at top speeds down highways.
The First Rough Terrain Crane
The first rough terrain crane was put on the market by Grove in the year 1959. The crane was intended for application and designed to handle various tasks on construction sites. The crane's tires have the industrial strength that is capable of handling all kinds of tricky terrain and is able to transport small loads in carry mode. During the 1970s, the 4 axle Super-RT 1650 model was introduced by Grove. This particular unit has an 82.8 meter or 270 foot height under hook in production, in addition to a 135 ton lifting capacity. At the end of the day, the rough terrain crane would become the company's most notable machine through the years.
The Crane's Disadvantages
Among the main drawbacks of the rough terrain crane was the problem that it was not capable of being driven on public highways with any other traffic. Japan was the only nation in the world which will make an exception to this rule. Moreover, another issue happened when the lowered boom on the crane tended to block the left and right views of the driver, depending upon how the cap was placed. These problems with the design of the crane ended up being both serious and dangerous and result in many RT crane mishaps, specially when turning. As a result, low-loaders, lowboys, flatbeds were used as the primary way of moving rough terrain cranes.
