In the crane industry, the all-terrain crane is a luxury type of a mobile hydraulic crane. The reputation of this crane is like driving a Hummer or a Range Rover on pavement. All-terrain cranes are considered to be a hybrid between a rough terrain crane and mobile truck crane. Another great feature of this machine is its multi-functional ability to be able to navigate through all types of off-road terrain. Amongst the main selling characteristics of this crane is that it travels equally well at high speeds down roads.
The First Rough Terrain Crane
Grove introduced the first rough terrain crane to the market in the year 1959. The crane was designed for the intended application of being a multi-purpose equipment for use on construction locations. The industrial strength of the crane's tires could handle all types of tricky terrain and is able to transport small loads in carry mode. In the 1970s, Grove launched the 4 axle Super-RT 1650 model. This specific unit 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 company's most remarkable equipment over the years.
The Crane's Drawbacks
The rough terrain crane is not without its disadvantages as it is not able to be driven on public roads with any other traffic. Japan is the one country that has made this rule an exception. In addition, another issue occurred when the lowered boom on the crane tended to block the driver's right and left views, that depends upon how the cap was positioned. All the problems with the design of the crane ended up being both severe and hazardous and result in many accidents with RT cranes, especially while turning. Therefore, flatbeds, low-loaders, lowboys were adopted as the primary way of transporting rough terrain cranes.
