    Abstract: A hoist system includes a winch drum and an air motor coupled to the winch drum. The hoist system further includes a brake coupled to the winch drum and operable to stop rotation of the winch drum and an over-speed sensing device configured to sense a speed of the winch drum. The over-speed sensing device includes a pneumatic switch operable to disconnect an air supply from the air motor and engage the brake to stop rotation of the winch drum and a centrifugal clutch coupled to the winch drum and configured to rotate at a rotational speed proportional to the speed of the winch drum. The centrifugal clutch operates the pneumatic switch when the rotational speed of the centrifugal clutch reaches or exceeds a threshold rotational speed.

    Abstract: A pulling tool is provided with a rotatable drum having a cable wound thereon. A motor is drivingly connected to the rotatable drum and the rotatable drum and motor are disposed within a unique housing structure. The rotatable drum is driven by a planetary gear system that is disposed within the rotatable drum to provide a compact assembly. A belt and pulley system is provided for delivering torque from the motor to the planetary gear system. The rotatable drum is provided with a two-piece stepped construction that allows the planetary gear system to be assembled within the drum and allows for the initial wraps of a cable around the smaller diameter portion of the stepped drum.

    Abstract: A task input is received at a well service rig. The maximum allowable speed is determined for the task. Current block speed inputs are received. The throttle position for the engine controlling the block is evaluated to determine if the block is to be sped up or slowed down. When the throttle position indicates the operator is attempting to speed up the block, the current block speed is compared to the maximum allowable speed and the engine is only allowed to speed up the block up to the maximum allowable speed, at which point the operators control of block speed is limited to reducing block speed. Each task can have multiple maximum allowable speeds, which can vary based on specified conditions. When the hookload is light or the remaining equipment in the well is small, the lock-up feature for the transmission can be disengaged in addition to the block speed governing feature.
