Product Description

DW311 (CYTJ45) mining hydraulic tunneling jumbo


Introduction: It is a small and medium-sized hydraulic rock drilling equipment independently researched, developed, and manufactured by our company. It is mainly suitable for blasting and bolting operations required for excavation of tunnels, mining, hydropower, railways, highways, and other fields;


It adopts an advanced fully hydraulic rock drilling system, equipped with an anti jamming drill device. It has a compact structure, and the drilling arm is extendable. It can perform multi angle and multi-directional drilling relatively parallel to the working section. The climbing ability is ≤24%, the walking speed can reach 12km/h, transition speed is fast. It is an excellent underground mining and tunnel excavation mechanized drilling equipment.

Adaptation range

The whole machine has the function of rotating 360 degrees in multiple dimensions, drilling in all directions, truly drilling without dead angles, and suitable for cross-sectional areas up to 31m²;


High security

Adopting a sturdy ceiling that can be lifted and protected, ensuring the safety of operators, safety is the benefit;


High work efficiency

Direct control rock drilling system, equipped with automatic anti jamming function, automatic end point retraction function, using different hydraulic pumps for impact, rotation, and propulsion. Low pressure and high flow hydraulic system takes into account efficient rock drilling, preventing drill rod lock up, improving drill rod consumption, and reducing operating costs;


Trolley arrangement

Ensure good visibility for operators, and the powerful four-wheel drive articulated chassis ensures flexible, fast, and safe driving in narrow tunnels;
