Product description

The trench cutter is a type of construction equipment designed to dig narrow but deep trenches used in the casting of slurry walls. Typically, it is a cutter attachment mounted on a crawler crane base machine, with different types of hose handling systems. The machine excavates by cutting the soil using two cutting wheels, while a powerful pump extracts loose material mixed with some of the slurry, typically betonite. JTC 40A trench cutter has the following features:

  • Equipped with advanced telescopic crawler undercarriage, it features  high strength, high stability and high reliability, well meeting various working conditions and easy for transportation.
  • Eco-friendly, electro-controlled, turbocharged, imported Cummins diesel engine, powerful and high torque output, well matched with reliable hydraulic system, lower fuel consumption and high efficiency.
  • Adopting imported double-speed gear box, main winch can accurately control trench cutter's quick up-down motion and low speed feed. Electro-hydraulically proportional follow-up control system can ensure the synchronism of slurry hose drum, hydraulic hose drum and main winch.
  • Front/rear single rope and dual winches substantially improve the rope's service life and safety.
  • High output torque of cutter wheels, high working efficiency, and applicable for various soil layer and hard rock layer with different cutting teeth.
  • Equipped with advanced inclinometer, longitudinal and lateral adjustment devices, it can provide high accuracy Omni- adjustment, recording and drawing the wall curve in real time, effectively guaranteeing the wall quality and accuracy.
  • Adopting various advanced control ways, including full power control, electric override control, load sensing control, electro-hydraulically proportional control and others, equipped with imported hydraulic parts, realizing high efficiency, high accuracy and high reliability.
  • Apile Foundation have independently developed advanced and reliable electronic control system,  integrating engine monitoring system, working condition monitoring system, adjustment system, hose synchronizing system, breakdown inspection and alarm system.
