Success Story: Rock Drill

Increase Safety Without Sacrificing Productivity

 

A customer of Applied Fluid Power manufactures a rock drill that is used for many different drilling functions in either quarries or mines. This operation can be dangerous, however, as this type of machine’s human machine interface was on the machine itself, putting the operator in danger.

The goal: Keep the operator safe without sacrificing efficiency or accuracy of control.

The Key Challenge

 

Project Goals

  • Create a system that would accurately and efficiently control the rock drill remotely.
  • Combine all controls into one easy-to-operate radio remote.
  • Create a telematics solution that is economically responsible.

Solution

 

Applied Fluid Power had significant input into the hydraulic design of the original rock drill, which already contained some electrical integration. For this project, the original design was enhanced to provide remote control of the rig functions. However, controlling the machine from a distance made it hard to see the work area, which could lead to far less accurate operations. Cameras built into the rig allow the operator to see the work area from a distance.

Technology Overview

 

Hydraulic components:

  • Two 420 pumps
  • Two Gear Pumps
  • Custom Manifolds
  • 4 DPC130 valve stacks, 21 sections total
  • HAD supplied 90 series Motor with one for feed
  • Return Filter
  • Heat Exchanger

Electronic components:

  • Radio Control Transmitter (Belly Pack)
  • (2) HFX 48 and HFX 12 Controllers
  • Wireless vision system with cameras and display

Components were selected for two main criteria: the ability to perform all necessary functions, and cost effectiveness. The result was a machine that performed to standard without breaking the bank.

Customer Outcome

 

The customer had been working with Applied Fluid Power for over thirty years, so the choice was easy for the customer. Applied Fluid Power's expertise is evident in the fact that the machine is currently running to standard with no operational limitations.
