Excavator type masts

Leader masts are applied to drive up to 14-meter long piles with hydraulic or diesel pile hammers as well as to drill holes, 600 mm diameter, with a depth of up to 14 meters. These can be attached to crawler excavators with the mass from 30 tonnes.

Implementation example
Excavator type masts пример внедрения

Leader mast equipped with a BRUCE SGH-0512 series hydraulic hammer attached to HITACHI excavator to drive up to 14-meter long 300x300, 350x350 and 400x400 mm piles.

Efficiency.

The leader masts help reequip an excavator and turn it into a pile driving or drilling rig. These can be attached to both home-produced and imported crawler excavators.

Design features.

Hydraulic cylinders and hydraulic clamps minimize preparation time.

Applicability.

The leader masts are compatible with diesel and hydraulic hammers as well as hydraulic rotary heads designed for drilling applications.

Universality

The leader masts can be easily attached to the customer’s base machine to modernize it and convert into a pile driving rig.

The masts are designed by the Kopernik Group of Companies engineering team. Our company develops requirements specification and manufactures various types of leader masts including excavator type MK-S, B, and M* series masts to drive up to 14-meter long piles. All the equipment is designed in accordance with the customer requirements.
