摘要: The present application relates to lifting equipment for a waffle slab used in a construction. The lifting equipment comprises a main body bracket, a sliding member and a plurality of clamping mechanisms. The main body bracket has a through hole in a center thereof. The sliding member is slidably disposed in the through hole of the main body bracket and is slidable between a first position and a second position. Each of the plurality of clamping mechanisms comprises a clamping member and a connecting rod. The clamping member comprises a first end and a second end, wherein the first end is pivotally connected to an outer edge of the main body bracket, and the second end is configured to extend into a hole of the waffle slab for clamping the waffle slab. A proximate end of the connecting rod is pivotally connected to a lower end of the sliding member, and a distal end of the connecting rod is pivotally connected to the clamping member between the first end and the second end.

摘要: A tension bar for an edge lift anchor for a concrete panel, the tension bar being shaped to provide a central portion to lie adjacent a head portion of the anchor and legs extending from each end of the central portion, an inner side of each leg being profiled to lock into the surrounding concrete, the profiling being formed by a series of longitudinally spaced formations each of generally saw-toothed shape with a leading edge of each formation facing towards the head portion such that on application of tensile load to the tension bar, the leg will lock into the concrete with a generally compressive loading being applied to the concrete in the zone between the two legs.

摘要: A machine for lifting and moving heavy slabs includes two channels connected only by a cable. The channels are placed against opposite edges of a slab. Each channel has a lower flange which is beveled so that the flange will scoop under the edge of the slab when moved toward the opposing channel. The channels are moved by attaching the cable to one channel and pulling the cable upward from the sheave on the other channel. Further lifting of the cable lifts the channels and the slab for moving.

摘要: A pipe handler for safely handling large pipes utilized in gas and oil lines, and the like utilizes a horizontal spreader bar having a dependent lifting arm hingedly attached at each end thereof. Each of the distal ends of the lifting arms includes a pivoted lifting shoe. The spreader bar is to be suspended from a crane. A winch having a double drum is mounted to the spreader bar and powered by an electric motor. Each drum includes a cable operatively connected to a respective one of the lifting arms. Initial operation of the winch causes the arms to swing outwardly. To handle a large pipe, the crane operator positions the spreader bar over a pipe to be moved, and operates the winch to swing the lifting arms outwardly sufficiently to allow the lifting shoes to thereafter swing inwardly to insert the lifting shoes into the respective ends of the pipe. The pipe can then be hoisted and moved to a desired point.

摘要: For laying and joining successive sections of pipe, a vehicle is movable over a course along which the pipe is to be laid. Carried on the vehicle is a crane, the outer end portion of which is movable both vertically and horizontally relative to the course of the pipeline. A controllable grapple mounted on that outer end of the crane is engageable with a section of the pipe, so that operation of the grapple together with the crane enables each section of the pipe to be picked up, moved into position over and deposited along the course. A vibrator is attached to the grapple and serves to induce vibration thereinto and from the grapple into the section of pipe being carried. The vibration is induced as an end of the section carried by the grapple is slidably mated with another section of the pipe which lies along the course. The vibration also is used to assist in bedding the pipe section being laid.
