摘要： A rotational drive assembly including a pair of pinion gears journalled on idler shafts disposed laterally on either side of a drive shaft and meshing with the teeth of a drive gear and a ring gear. The drive shaft is universally journalled for rotation and for permitting a limited range of movement of the drive gear toward and away from the ring gear to substantially equalize tooth contact between the drive gear and each of the pinion gears as the drive shaft is rotated. A slotted bearing may be provided to preclude excess lateral movement of the drive shaft.

摘要： A single stage, twin valve, variable torque converter has a vaned input impeller, a vaned, single stage output turbine and a twin valve all disposed in a fluid filled, generally torroid-shaped chamber of a housing. The torque converter by means of its twin valve provides a variable forward output torque for a constant input speed and also provides a low reverse torque. The twin valve consists of two connected, concentric cylindrical sleeves which can be moved axially into and out of the torroid-shaped chamber so that the first sleeve can be interposed between the vanes of the input impeller and the vanes of the output turbine and the second sleeve can surround the vanes of the output turbine and thus seal off the output turbine from the fluid within the torroid-shaped chamber of the torque converter and provide a low reverse torque.

摘要： A lift crane having a separated transporter-supported front ring segment and a transporter-supported rear works including a counterweight. The front ring segment is connected by a frame element to the rear works and supports a carrier which pivotally mounts a forwardly-inclined boom and a rearwardly-inclined mast. Movement of the carrier across the front ring segment is permitted by two equal-length links pivotally connected to opposite sides of the carrier and the respective opposite sides of a horizontal bracket mounted on the frame element. The center of rotation of the carrier as it traverses the front ring segment is substantially coincident with the imaginary vertex of a truncated isosceles triangle formed by the carrier and lines running axially along the links. When the carrier is centered on the front ring segment, the center of rotation is also substantially coincident with a vertical axis running through the rearward-most point of the mast. Since the rearwardmost point of the mast is substantially coincident with the center of rotation, this point of the mast remains substantially stationary during the movement of the carrier across the front ring segment. A fixed length pendant connecting the rearwardmost point of the mast to the rear works also remains substantially stationary and in a vertical plane during the movement of the carrier across the ring segment, thus minimizing the amount of side loads and torsional forces induced in the mast due to such carrier movement.

摘要： A crane assembly which, in heavy lifting configuration, has a platform with boom carrier and counterweight support rotatably mounted on a ring with the mounting including a king pin removably secured to the ring. The platform will easily accept a variety of hoisting machinery. Not only are the boom, mast and ring suitable for other crane configurations, but also the counterweight support and boom carrier are standard subcombinations held rigid with the platform through links defining triangular frames.

摘要： Separate torque converters are selectively clutched to the hoist and drag drums of a dragline machine with a selectively engageable clutch providing a power interlock of the output of both torque converters to either one of the drums as desired. The application and control of torque from the two torque converters to the hoist drum is in parallel and to the drag drum is in series progressive, i.e., the drag converter being engaged first and going from zero to maximum while the hoist converter goes from zero to about fifty percent of capacity as the drag converter reaches maximum. The reserve torque in the hoist converter may be selectively applied to the hoist drum to step the drag bucket up if the drag drum approaches a stall condition. The hoist converter may also be selectively engaged to apply a predetermined hold back force during bucket lowering. Another clutch may be engaged to interlock the two drums together for joint operation by the hoist converter. Thus, dragline holdback during hoisting may be achieved by the drag drum brakes, the drag drum converter or the drum interlock thereby providing the operator with considerable flexibility in controlling the path of the drag bucket during hoisting.

摘要： A load handling device is disclosed having an improved swing drive assembly including a hydraulically driven pivotally mounted swing drive pinion biased against a segmented ring gear by a hydraulic actuator with a guide roller adjacent the pinion engaging a guide flange concentric with the ring gear to limit the maximum tooth engagement between the pinion and ring gear and thereby provide essentially constant backlash on the pinion gear regardless of eccentricities or other irregularities in the ring gear during swing drive operation. When the swing drive pump is shut down a bypass valve is automatically actuated shunting the flow of hydraulic fluid around the pump and a spring operates to counteract the separating force between the pinion and ring gear due to wind induced rotating force which produces torque on the pinion as a result of the back pressure in the motor and the shunted supply-return lines.
