Abstract: A method of swing stopping control of a suspended load of a crane including a hoist and a trolley solves an equation of motion, given as an equation with respect to the deviation angle of a suspended load from the vertical direction when the trolley travels, for the trolley acceleration to thereby obtain the value of the acceleration or deceleration of the trolley, obtains speed patterns corresponding to the values of the acceleration or deceleration, drives the trolley according to the obtained speed patterns, and carries out control so that the deviation angle of the suspended load from the vertical direction becomes zero at the time when the acceleration or deceleration of the trolley is ended. Thus, even if the length of a rope holding the suspended load up is changed, a required speed pattern is produced to permit highly accurate positioning.

Abstract: A girder block lifting method, which can solve a problem that steel beams are inclined or fallen inward by lifting a heavy material, and a jack-up stage used therefor are provided. The method includes a main beam which can be provided between steel beams being targets of connection with the girder to construct a rigid frame structure, a height adjustment means (gate-shaped base) mounted on a cross beam member being parallel to the main beam and connecting other steel frames for adjusting height to the main beam, a connection beam for alternately connecting the main beam and the height adjustment means (gate-shaped base), and an auxiliary beam for connecting the connection beams. On a frame stage formed by connecting these beams, a plurality of lifting jacks are provided and a lifting sling is hung from upper part of the steel beam to enable jack-up of the girder block.

Abstract: A frying/boiling stand with hoist includes a hoist supported for rotation by opposed end frames. The hoist includes an axle, a centrally located spindle hood, and axle housings extending between the spindle hood and the opposed end frames. The axle centrally supports a cable having a lower hook, the cable forming a coil within the spindle hood. The hoist has a crank mounted on an end portion of the axle for turning the axle. A stop is located on one end frame for engaging the hoist. A food item is suspended by said hook over a fryer/boiler for raising and lowering by turning the axle crank. The food item, upon completion of cooking, is hoisted from the fryer/boiler by the hoist by turning the axle and the stop applied to maintain the axle fixed, thereby suspending the food item above the fryer/boiler for removal from the hook.

Abstract: A walk assist device including a mechanism for mechanically providing a lifting force to lift a patient from a seated position and provide a weight support force to a patient at an individually adjusted height level along the length of an exercise run.

Abstract: A skyline operates on a mountain side from an upper tail-block that is positionable along a transverse cable extending between two elevated anchor points. A balloon is attached to the upper tail-block to assist in supporting the weight of the skyline cable, and also the weight of the drop line carriage mounted on the skyline.

Abstract: A slack pulling carriage having a skidding line drum arrangement that achieves efficient and accurate movement of the carriage along the skidding line. The drum arrangement is preferably configured such that the skidding line loops around at least approximately 180 degrees of the circumference of the drum. A hydraulic driving system, a multiple speed motor and locking clamps are also disclosed.

Abstract: A lifting device for sick or motion-handicapped persons is disclosed. In the lifting device (1), both ends of the lifting belt (7a,7b) are fixed onto the central shaft of a belt wheel (5), and thus when a lifting motor (3) rotates the belt reel (5) via a reduction gear, both ends of the belt (7a,7b) are spirally wound on the belt reel (5), and, respectively, when the belt reel (5) rotates in the opposite direction, the belt (7a,7b) is freed from the belt reel (5). Hence, as the lifting is carried out supported at two points by means of the belt, the lifting will take place very smoothly and the lifting device will not twist.

Abstract: Apparatus for damping the swing of a loading device, said apparatus comprising a trolley provided with a hoisting machine having a hoisting rope on which a loading device is suspended, and downward-pointing brackets attached to the bottom of the trolley. A retaining lever provided with a joint, is mounted on each bracket enabling the lever to turn relative to the bracket. The loading device is so constructed that, when lifted up between the brackets, it will turn the retaining levers into a substantially vertical position. An anti-friction means is provided between the retaining lever and the loading device.

Abstract: A remote controlled slack pulling log skidding carriage is provided for feeding a slack drag line toward a log to be skidded. A drive sheave rotatably mounted in the carriage is operated by a hydraulic motor. The fluid to operate the motor is stored in one or more accumulators, and a radio controlled valve starts and stops the flow of fluid to the motor. A mechanically operated hydraulic pump also is provided to recharge the accumulators during a skidding operation. A reciprocating locking assembly is provided to alternately lock the carriage to the skyline or to the slack line.

Abstract: An arrangement for one or more tiltable drums that may be used in conjunction with cranes or other hoisting devices to overcome fleet angle limitations and controls the point of cross-over and reversal of the winding of the running line due to fleet angle limitations of the line when the load bearing blocks are brought near their high limit.

Abstract: Method of storing and transporting individual paper sheets abutting against each other to form a staple of sheets, in which a precompressed staple of sheets resting between upright support members on a support surface of a first magazine is gripped at opposite ends by clamping jaws of a gripper, which compresses the staple further to a self-supporting body, whereafter the body is lifted from between the support members of the first magazine and transported between support members of a second magazine, spaced from the first, at which the body is then relaxed by removing the clamping jaws; and an arrangement for carrying out the method.
