Power take-offs (PTO) are extensions of a vehicle's drive train that can be engaged to power auxiliary equipment such as plows, augers, winches, and many other material handling, construction, and agricultural implements. Power take-offs require special handling and safeguards because of the danger of becoming entangled in the moving shaft. Split shaft power take-offs are designed to allow one engine to drive both the vehicle and the auxiliary equipment. Splitshaft PTOs can provide engine power to either the vehicle’s drive axle or to the equipment by switching the mode of operation with the main clutch in the gearbox. This type of power take-off is designed to run either the vehicle axle or the auxiliary equipment, not both at the same time. Splitshaft PTOs are used to power oil drilling rigs, concrete pumpers, compressors, pumps, and lifts. Power take-offs are operated at very high speeds and pose a danger to operators. Power take-offs must have well-maintained and properly fitted guards or shields when they are being operated to protect people from getting entangled in the shaft. PTO shielding consists of a guard that covers both the top and the sides of the power take-off, and encloses the entire drive shaft of the PTO from the tractor or truck to the first bearing on the auxiliary equipment. A PTO shaft shield must be properly fitted to cover the entire exposed length of the shaft and may also have to accommodate for the vertical and lateral movements of the power take off. Power take-offs are also commonly used with trucks to power auxiliary units, such as dumping or tipping mechanisms, compactors, snowplows, cranes, and lifts. A truck power auxiliary unit may also include a cement mixer, fire equipment on a fire truck, sewer cleaning trucks, and sweeper vehicles.
