The all-terrain crane is considered within the crane industry as being a luxury kind of a mobile hydraulic crane. It has the status of being similar to driving a Hummer or a Range Rover on pavement. All-terrain cranes are considered to be a hybrid between a mobile truck crane and rough terrain crane. One more remarkable feature of this machine is its multi-functional ability to be able to traverse through all kinds of off-road terrain. Among the main selling characteristics of this crane is that it travels equally well at top speeds down roads.
The First Rough Terrain Crane
Grove introduced the first rough terrain crane to the market during 1959. The crane was designed for the intended application of being a multi-purpose device for application on construction sites. The industrial strength of the crane's tires could handle all types of difficult terrain and could move small loads in carry mode. During the 1970s, the 4 axle Super-RT 1650 model was launched by Grove. This particular model has a 270 foot or 82.8 meter height under hook in production, along with a 135 ton lifting capacity. At the end of the day, the rough terrain crane will become the most notable machinery of the company over the years.
The Crane's Drawbacks
One of the main drawbacks of the rough terrain crane was the problem that it was not capable of being driven on public roads with any other traffic. Japan was the only country within the globe that will make an exception to this rule. In addition, another issue occurred when the lowered boom on the crane tended to block the left and right views of the driver, depending upon how the cap was positioned. All the problems with the design of the crane ended up being severe and dangerous and result in many accidents with RT cranes, particularly while turning. As a result, low-loaders, lowboys, flatbeds were utilized as the primary means of moving rough terrain cranes.
