The all-terrain crane is considered within the crane industry as being a luxury model 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. Another great quality of this machine is its multi-functional ability to be able to traverse through all kinds of off-road terrain. One of the main selling characteristics of this particular crane is that it travels equally well at high speeds down roads.
The Very First Rough Terrain Crane
Grove launched the very first rough terrain crane to the market during 1959. The crane was designed for the intended use of being a multi-purpose machinery for application on construction sites. The industrial strength of the crane's tires can handle all types of difficult terrain and could move small loads in carry mode. In the 1970s, Grove introduced the 4 axle Super-RT 1650 model. This 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 most notable equipment of the company through the years.
The Crane's Drawbacks
Amongst 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 globe that will make an exception to this rule. In addition, another problem happened when the crane's lowered boom tended to block the left and right views of the driver, depending upon how the cap was placed. All these issues with the crane's design ended up being both hazardous and severe and lead to many accidents with RT cranes, especially while turning. Thus, lowboys, flatbeds, low-loaders were utilized as the primary means of transporting rough terrain cranes.
