The all-terrain crane is considered in the crane business as being a luxury type of a mobile hydraulic crane. It has the status of being similar to driving a Range Rover or a Hummer on pavement. All-terrain cranes are considered to be a hybrid between a rough terrain crane and mobile truck crane. One more remarkable quality of this machinery is its multi-functional ability to be able to traverse through all types of off-road terrain. Amongst the main selling characteristics of this particular crane is that it travels equally well at top speeds down highways.
The Very First Rough Terrain Crane
Grove introduced the very first rough terrain crane to the market during the year 1959. The crane was designed for the intended application of being a multi-purpose machine for use on construction sites. The crane's tires have the industrial strength which is capable of handling all types of tricky terrain and could move small loads in carry mode. In the 1970s, Grove launched the 4 axle Super-RT 1650 model. This model has a 270 foot or 82.8 meter height under hook in production, in addition to a 135 ton lifting capacity. At the end of the day, the rough terrain crane will become the most remarkable machinery of the company through the years.
The Crane's Disadvantages
Amongst 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 world that will make an exception to this rule. Moreover, another problem happened when the lowered boom on the crane tended to block the right and left views of the driver, that depends on how the cap was placed. These issues with the design of the crane ended up being both severe and dangerous and result in many RT crane mishaps, especially when turning. As a result, lowboys, flatbeds, low-loaders were used as the primary way of transporting rough terrain cranes.
