The objective of this contract was to design, fabricate, and laboratory test a multipurpose test chassis to provide transport, power, ancillary systems, and instrumentation for the testing of prototype roof drilling and bolting equipment. During the contract, modification authorized the fabrication of two additional test chassis. The basic chassis is a modified Lee-Norse drive storage unit. This chassis was selected because of its tracked propulsion system which provides low ground pressure and high maneuverability. Transport of the system being tested is provided by attachment to the hydraulically elevatable front mounting plate on the chassis. Power for testing is provided by five independent hydraulic circuits. Electrical (110 and 220 volts AC) and pneumatic (3 scfm at 125 psi) power are also available for control system use. The test chassis design also includes a vacuum dust collection system. An instrument panel allows for monitoring of hydraulic supply pressures and hydraulic return pressure, flow, and temperature. Dust collection, compressed air, and electrical system parameter instrumentation is also provided. Fabrication of the units proceeded generally on schedule with the exception of significant delays caused by late delivery of the electric drive motors, problems with the tram control system, and delays in MSHA approval. The three test chassis have been delivered. (ERA citation 06:023064)
