The digger derricks we have available feature stout, reliable design. They were made to make a number of tasks simpler, ranging from digging holes and lifting and setting poles to turning in screw anchors, putting linemen in the air and setting transformers.

Digger derricks are also commonly used by electric, telecommunications and construction industries.

  1. Telephone Pole Installation- A digger derrick can dig a hole up to 18 inches round and 10 feet deep. It can dig the hole for the telephone pole as well as lift and place the pole in the ground.

  2. Electrical Pole Installation- Much like the telephone pole installation, digger derricks are also used to install electrical poles and wiring.

  3. Electrical Work-Digger derricks can be used to fix electrical wires that have been damaged due to storms or other natural disasters.

  4. Trimming Tree branches- Because of the ability to reach heights, digger derricks can be used to transport workers to trim tree branches so they won’t get in the way of the electrical wires and cause unnecessary power outages or wire damage.

  5. Road work-Digger derricks can be used to take personnel below ground to make underground repairs to things as well as fixing potholes in the road.

Digger Derrick Safety

With all kinds of heavy machinery, there is safety procedure workers must follow. That's no different with digger derricks. First and foremost, workers should be sure to invest in a reliable truck that has the proper specifications for a given job. A quality digger derrick will have lower and intermediate booms made from high-strength steel, as well as a system to protect the hydraulic system from overload. Some trucks include gauges such as a digger / winch pressure gauge which monitors the pressure that is generated while the digger and / or the winch is in use, as well as others that monitor boom pressure while in use.

Safety Tips:

  • Structural limits: plain and simple, you should know your truck’s structural limits. 

  • Check range of motion: Before every shift, workers must perform a test of all of the range of motion functions, according to the American National Standards Institute (ANSI A10.31).

  • Travel height: Before workers head out to a job or back to the shop, they should verify that the boom is properly stored so that the truck is not higher than its posted travel height.

  • Sufficient winch line: Workers should be sure to keep at least five wraps of line on the drum. This ensures that the drum unit will safely handle the load.
