The all-terrain crane is considered in the crane business as being a luxury type of a mobile hydraulic crane. It has the reputation 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. Another great feature of this machine is its multi-functional ability to be able to traverse through all kinds of off-road terrain. Amongst the main selling characteristics of this crane is that it travels equally well at high speeds down roads.
The Very First Rough Terrain Crane
The very first rough terrain crane was put on the market by Grove in 1959. The crane was intended for use and designed to deal with many tasks on construction sites. The crane's tires have the industrial strength that is capable of handling all kinds of tricky terrain and can move small loads in carry mode. In the 1970s, Grove launched the 4 axle Super-RT 1650 model. This specific unit has an 82.8 meter or 270 foot height under hook in production, together with a 135 ton lifting capacity. At the end of the day, the rough terrain crane would become the company's most notable machinery over the years.
The Crane's Drawbacks
Among the main disadvantages 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 nation in the globe which would make an exception to this rule. Moreover, one more issue occurred when the crane's lowered boom tended to block the driver's left and right views, that depends upon how the cap was positioned. All these issues with the crane's design ended up being both dangerous and serious and lead to many accidents with RT cranes, particularly while turning. Thus, flatbeds, low-loaders, lowboys were adopted as the main way of moving rough terrain cranes.
