A sleeve block includes a frame that is connectable to an object, such as a truss, that is to be moved relative to a stationary support. An axle defining a longitudinal axis and a motor are to the frame. The sleeve block includes a line that has a first end connected to the motor. The line extends downward from the motor around at least a portion of the axle and then extends outwardly of the frame so that at least a portion of the line is operatively connected to the stationary support. The portion of the line between the axle and the stationary support creates a line axis, and the motor is spaced apart from the line axis. Activation of the rotatable output of said motor causes the frame and the object to move relative to the stationary support by retracting or extending the line from the motor.
