Drill Rig Hydraulic Cylinders

Application Scope of Drilling Jumbo Hydraulic Cylinders

1. Functions of Each Type of Hydraulic Cylinder

1. Feed Cylinders
Provide constant thrust for rock drilling, push drill bits into rock formation and retract drill rods after drilling, control the feed speed of drilling process.

2. Boom Luffing & Lifting Cylinders
Adjust the vertical height and pitching angle of the drilling boom, enlarge the working range for tunnel vault, side wall and bottom holes, and fold the boom for vehicle transportation.

3. Boom Swing Cylinders
Drive the drill arm to swing horizontally left and right, accurately position drilling points without moving the whole drilling vehicle.

4. Outrigger Stabilizer Cylinders
Support the chassis to eliminate vibration during percussive drilling, guarantee equipment stability on uneven underground ground, prevent slipping and overturning.

5. Drill Head Angle Adjustment Cylinders
Tilt the rock drill to drill horizontal, upward and inclined anchor holes, meet different surrounding rock reinforcement requirements.

6. Manipulator Clamping Cylinders
Realize automatic loading and unloading of drill pipes, lower labor cost and improve underground operation safety.

2. Main Application Fields

• Road and railway tunnel anchor bolt support & blasting hole drilling
• Hydraulic engineering tunnels, underground cavern surrounding rock reinforcement
• Coal and metal mine underground roadway excavation and roof bolting
• Subway, municipal pipe gallery foundation pit anchoring construction
• Mountain slope, dam and open-pit mine slope stabilization projects

Brief Product Overview

These series hydraulic cylinders are specially customized for rock drilling jumbos, bolt drilling rigs and tunnel boring machines, undertaking drilling feeding, boom positioning, vehicle stabilization and automatic pipe changing tasks, widely used in tunnel engineering, underground mining and geotechnical slope reinforcement.
