Manufacturing Methods and Technology (MM&T) Measure for Fabrication of Silicon Transcalent Transistor.

The purpose of this test is to provide evidence of production contractor conformance to contractural requirements, reveal defects of workmanship or material nature that may reduce the effective operation of these vehicles in the field and to compare existing quality with previous standards. Two M840 Dolly Sets were provided for testing. The dolly sets each consits of a front and rear dolly trailer. The sets contain air-over-hydraulic brakes, air-spring suspension, automotive type shock absorbers, a quickly removable hinged towing bar, taillights and stoplights and standard military tires. Mechanical hand parking brakes are provided for the rear wheels. Each dolly is equipped with an independent, manually-operated hydraulically-actuated lifting/leveling system. A lifting leveling jack is connected between each lifting bracket and a torque tube arm. Two tilting jacks are mounted on each torque tube and may be actuated to align the transporter with the mating brackets on the shelter when on uneven terrain. Two hydraulically operated lifting jacks and two hydraulically operated tilting jacks are provided on each dolly for lifting and leveling a shelter. These jacks provide the means of installing the dolly set to the shelter when resting on the ground and to lift the shelter to a height of 17 inches for tactical deployment. The dolly set has a rated payload of 9000 lbs. The M840 Dolly Sets successfully met the requirements of the Performance Tests.
