Feature:

(1).Adopt special designed chassis and track roller for Pipelayer

(2).Turbo intercooler CUMMINS engine, which reserves enough power to meet any tough working condition.

(3).The counterweight adopt four-bar linkage design which has excellent stability and more extending distance, thus reduce the whole weight of the machine

(4).Well-equipped safety device such as automatic load moment limiter, hoisting height limit switch, boom buffer limiter device, make operation more safe.

(5).Modular design has facilitated removal /installation of components and shorten machine downtime.

(6).Customized integrated solution for different working environment such as the frigid zone , the tropics ,deserts and marsh area.
