Telescopic Dipper Arm

As the name suggests, a telescopic dipper arm is a highly specialized, purposed-built attachment with a sophisticated telescopic mechanism. Your investment value of a telescopic dipper is fully realized when excavation work needs to be carried out in an extreme confined space or picking up material from a pit where a long reach front attachment still deems to be too cumbersome.

Most commonly seen solutions in overcoming such challenging situations is to employ a crane fitted with a cable operated clamshell bucket. The cycle time of this crane solutions is extremely high as compared to a hydraulic operated telescopic dipper arm with a clamshell bucket front attachment. An ingenious implementation and integration of hydraulic system with cable and sheaves make up the key integral system in operating 2 sliding elements within the outer housing.the key integral system in operating 2 sliding elements within the outer housing.

A telescopic dipper attachment for a 20 ton and 35 ton class excavator could enjoy up to 20 meter and 25 meter digging depth respectively if desired, and the beauty is, its only require very small working radius. If you are challenged by space and depth constraint at the work site, there is simply no other better option than counting on a telescopic dipper attachment.


  • Designed for material handling application, excellent accessibility to deep and narrow pits.
  • The most efficient solution for work sites with restricted space and vast depth.


  • New hybrid design, extension and retraction is by means of a hydraulic-mechanical system.
  • Constructed with high strength steel to minimize overall weight while maximizing bucket capacity.
  • Sliding or articulating operator cabin.
  • Pressure sensors are installed on the telescopic arm to reduce impact upon the clamshell hitting the ground.

Gone are those design where parts, components and messy cable were mounted externally. Prone to both weather beating and accidental mishandling.

And now thanks to the new generation design with much improved aesthetic and weight distribution. What’s more important is there is no exposed component, the mechanism is cleverly concealed within the outer housing, drastically cutting down the frequency for maintenance, and greatly reduced the possibility of unnecessary damaged part due accidental mishandling which would inevitably leads to costly down time.

The productivity of a telescopic attachment will scale to a new level with our articulating operator cab system. Operator can now easily adjust (up, down, forward, backward) the cab to an optimum position where he can have the best aerial view to carry out the job not only effectively, but also enhanced the safety of personnel on the ground.

Controlling of cab movement is made easier by mean of joy stick system at the command of the operator.
