The Power And Versatility Of Digger Derrick Trucks
Digger derrick trucks are impressive and often awe inspiring machines that perform
multiple roles that could once only be done by heavy stationary equipment. These specialized boom trucks were developed as a cost effective, mobile, yet powerful solution to the problem of digging holes for telephone and electric poles. For this role they have since proven unbeatable.Previously, it was too impractical to use a drill rig to dig holes for utility poles, as it would need to be assembled, used, and then disassembled and reassembled again at the next drill site, often close by. Before digger derrick trucks were developed, holes for utility poles were dug manually and painstakingly by large crews of workers, using picks and shovels. This meant progress was slow, and expensive.
A digger derrick truck is an auger mounted on a boom and then bolted to a truck. The power and precision of the auger, the flexibility of the boom, and the mobility of the truck mean that digging holes for phone poles can be done in a fraction of the time it used to take, at a lower cost and with much greater precision. More powerful digger derrick trucks are equipped with augers that can bore clean through solid rock.
Because digger derricks are boom trucks, they are also designed to install the poles as well, using the boom to place the poles in the correct position. The task of digging holes for utility poles and installing them once took several men; the digger derrick truck can be operated by as few as two people.
Although the primary purpose of digger derrick trucks is to dig the shallow holes required for utility poles, or even for piers in construction, they can be and are frequently built to dig holes all the way down to well depth. The boom on a digger derrick truck is an extremely versatile tool with many applications. When fitted with buckets, digger derrick trucks can function as bucket trucks and used to lift workers up to tree branches for pruning or even picking fruit.
A bit more complicated to operate than typical boom trucks, digger derrick trucks do require some training to operate. They are somewhat more specialized than ordinary boom trucks or bucket trucks, and they are potentially dangerous in untrained hands, there is also a license required to operate a digger derrick truck. Qualified operators need to master a specific set of skills such as:
Digger derrick daily and pre-operational inspection.
Unit setup and operation.
Material handling and load capacity.
Hand signals, safety and OSHA regulations.
digger derrick trucks are used by virtually every utility company; construction companies use them for a variety of purposes as well. Because need for such machinery is sporadic rather than constant, companies more often opt to buy them used.
