Perforadoras horizontales

jt 520

Características principales


  • La DITCH WITCH JT520 es una máquina compacta para perforación horizontal dirigida, ideal para trabajos en zonas urbanas y áreas residenciales.
  • Esta máquina puede instalar hasta 2 tubos de 50 mm de diámetro en distancias de 50 m o más, dependiendo de las condiciones del terreno.
  • El tamaño de esta máquina la hace fácilmente transportable en un camión.


El motor diesel de 28,5 HP que equipa esta máquina proporciona un par de 678 Nm con una fuerza de empuje de 20 Kn y una fuerza de tiro de 22,2 Kn.


Las funciones de empuje, rotación, son totalmente independientes, con lo cual no restan potencia una a otra.

Cuenta con un cargador de 46 m de barras de perforación.

Sistema de anclaje hidráulico.

Mando de control con todas las operaciones integradas.

Ditch Witch JT520 The JT520 is a compact directional drilling system ideal for shallow-product installations in urban and residential areas. Designed for multiple installations per day, the JT520 is capable of pulling two-inch (50 mm) or smaller diameter conduit up to 150 feet (46 m) depending on soil solutions. The system can be transported with a ¾ ton pickup truck and the unit fits through a 36-inch (91 cm) yard gate.


28.5 gross hp (21.25 kW) diesel engine delivers high spindle speed of up to 195 rpm and peak torque of 500 ft•lb (678 N•m). Maximum thrust is 4500 pounds (20 kN) with 5000 pounds (22.2 kN) of pullback.


Thrust/rotation and fluid/auxiliary functions can all be run simultaneously without one function robbing power from the others.

Flat-style pipe wrench system breaks joints without damaging drill pipe.

Carries 150 feet (46 m) of UFE drill pipe with a 70 foot (21.3 m) bend radius allowing shallow installations without exceeding pipe capabilities.

Powerful single-auger design decreases amount of time needed to set up machine.

Single-handle control operates both thrust/pullback and rotation with variable speed for all functions.


Foot-controlled pipe lubricator speeds operation.

Adjustable drill frame set-up angle from 11-18 degrees meets varying jobsite requirements.

Drilling operator can single-handedly manage the 16 pound (7.25 kg) drill pipe.

Integral ground drive allows one person to load and unload the drilling unit.
