Improve Old Mining Machinery

Supplier: Custom Fluidpower

Improve safety and efficiency of old mining machinery, without the cost of new equipment.

Custom Fluidpower, a national hydraulic solutions provider, is in an ideal position to meet this need with the design and build capabilities to improve the safety and efficiency of underground machinery.

An example of an upgrade conversion is in the case of a customer who had an old air track drill rig, the purpose of which is to complete bolting projects (strata roof control) and repair in underground coal mines.

The existing machine required a large volume of high pressure air, the supply of which could not be guaranteed in the areas where the machine operated.  This could cause the machine to be inoperable resulting in costly downtime and safety concerns.  The machine also was not up to current safety standards as it had no braking system and unreliable steering systems, amongst other issues.

Custom Fluidpower reduced the air requirements by replacing the pneumatic traction motors with Sai Hydraulic motors.  The existing air motor driving the hydraulic pump was replaced with a tandem system, and actuators were fitted to the tramming valves to allow the valves to be operated from a pneumatic pendant.  These changes kept the machine simple to repair and service without the use of electrics.

A pneumatic pendant was constructed to operate the tramming function, allowing the machined to be trammed remotely and removing the operator from a dangerous interaction zone behind the machine.  The pendant was fitted with a two-hand control module, reducing the chance of unplanned movement.

Another key area was the addition of hydrostatic braking, through use of a Sai F21 brake and a Custom Fluidpower manifold.  The steering of the machine was improved dramatically, again resulting in increased efficiency and safety.

This example gives an indication of the possible improvements which could be made to existing mining equipment. Custom Fluidpower can enhance your mining machine efficiency whilst improving safety, without the need for the costly purchase of new equipment.
