KM Series Clamshell Telescopic Arm

Our telescopic arm for excavators is designed to complete complex underground construction projects. Excavators with telescopic arms have a longer reach and are more efficient than long-reach excavators. Ideal for busy urban environments, it is compact, quiet and offers excellent visibility to ensure projects are completed safely and efficiently.

Working Range of KM260
Equiped with CAT336D/336DL Excavator

 

  • The body is designed and fabricated using high strength steel plates to increase the life span by more than 50%.
  • Maintenance holes are designed along the structure for easy maintenance of wire rope.
  • Modular design is adopted to efficiently match with the chassis of the different brands of excavator resulting in the multi-functional usage of the excavator to effectively lower the cost of investment.
  • The use of wire rope specially designed for construction machinery, coupled with the well-designed pulley layout to reduce the wear and tear of the wire rope to improve its service life.
  • Mature and reliable touchdown protection technology is adopted to prevent the wire rope from twisting thereby to improve the service life of the wire rope and to reduce the rate of failure.
  • Unimate telescopic arm is a special working device to be installed on the boom of the excavator. Compared with the bigger rotary radius required by an extended arm, Unimate telescopic arm is a flexible tool for deep excavation within a restricted area.
