A system for lifting a load via a spreader bar includes a spreader bar and a swivel lug assembly. The swivel lug assembly includes an upper swivel, a lower swivel, and a load pin extending between a pair of load pin holes in the upper swivel and the lower swivel. The upper swivel is pivotable relative to the lower swivel about the load pin. The spreader bar includes two opposing sides each having a height, and spreader bar pin holes in each of the sides. The spreader bar pin holes are located at a midpoint of the height of each of the sides. The load pin is detachably attached to the first swivel lug assembly through the pair of load pin holes in the upper swivel and the lower swivel in order to releasably attach the swivel lug assembly to the spreader bar via two opposing spreader bar pin holes.

A method for installing pipeline segments within a conduit. The method includes a step of securing a first pipe segment of the pipeline segments at a top end of the conduit, a step of aligning a main axis of a second pipe segment of the pipeline segments with the main axis of the pipeline, a step of lifting the second pipe segment from a first position associated with a bottom end of the conduit to a second position adjacent to the first pipe segment, a step of abutting a top rim of the second pipe segment against a bottom rim of the first pipe segment, and a step of attaching the top rim of the second pipe segment to the bottom rim of the first pipe segment.

A hoisting assembly for lifting a load into an attic or lowering a load therefrom includes a hoist. The hoist comprises a housing, which has a drum or a lift wheel engaged thereto and positioned in an interior space defined thereby. A suspension module is engaged to and extends from an upper end of the housing. The suspension module can selectively engage a beam so that the housing is suspended from and removably engaged to the beam. A lifting medium is operationally engaged to the drum or the lift wheel and extends from a lower end of the housing. A connector is engaged to the lifting medium distal from the housing. The connector can selectively engage a load so that the load is removably engaged to the lifting medium. The hoist thus is configured to lift the load.

A hoist cage assembly for lifting a pallet with a crane includes a cage that has a bottom end that is open for positioning around a pallet of material. The cage has a plurality of bar openings each extending through the cage. A plurality of bars is each of the bars is slidable through a respective pair of the bar openings to extend through the pallet when the cage is lowered over the pallet. Each of the bars rests on the cage when the cage is lifted to lift the pallet when the cage is lifted. A plurality of sleeves is each of the sleeves is coupled to the cage and the sleeves are strategically arranged on the cage thereby facilitating each of the bars to be slidably stored in the plurality of sleeves.

This crane is provided with: a boom; a wire rope suspended down from a leading end section of the boom; a suspender that is fixed to a lower end of the wire rope and is for suspending a slinging tool for hanging a load; a calculation unit that calculates a first load, which is the weight of a member that is suspended down from the suspender; a slinging tool database unit that stores information pertaining to the slinging tool corresponding to the first load; a determination unit that determines whether a load is being suspended from the suspender; and a control unit that acquires the information pertaining to the slinging tool corresponding to the first load from the slinging tool database unit if the load is being suspended, and sets the vertical length of the slinging tool on the basis of the acquired information pertaining to the slinging tool.

A braided rope includes a plurality of braided strands comprising twisted yarns. Each of the twisted yarns includes a blend of first fibers and second fibers. The first fibers are high modulus polyethylene (HMPE) fibers and the second fibers may be lyotropic polymer filaments, thermotropic polymer filaments, or polyphenylene benzobisoxazole fibers. The first fibers can have a creep rate of no more than 3.0×10.sup.−8 percent per second at 20° C. while subjected to a stress of 5.0 grams/dtex. The first fibers can have a creep rate of no more than 1.0×10.sup.−7 percent per second at 20° C. while subjected to a stress of 7.5 grams/dtex.

A vertical lift system includes a cable with a pair of mounting loops positioned at opposite end portions of the cable, a lift bar, and a pair of cable blocks mounted to the lift bar at opposite end portions of the lift bar. The cable is mountable to the lift bar at the pair of cable blocks. A lift block is mounted to the lift bar between the pair of cable blocks. A spreader bar is mountable to the cable. The spreader bar includes an elongated shaft and a pair of cable couplings mounted to elongated shaft at opposite end positions of the elongated shaft. The cable is extendable through the pair of cable blocks on the lift bar and the pair of cable couplings of the spreader bar such that spreader bar is positioned between the lift block and the pair of mounting loops of the cable.

There is described a hoisting system and method of lifting that make use of a particular fibre rope. The fibre rope includes a plurality of magnets that are embedded within the fibre rope and spaced apart along the rope with a known axial distance between the magnets. The system may include a fibre rope hoisting speed sensor, and a magnetic field sensor that can sense the presence of the magnetic field of the embedded magnets. Using the sensors, the hoisting speed of the rope may be determined by: measuring the time between the passing of consecutive magnets by using the magnetic field sensor; calculating the distance between consecutive magnets using the hoisting speed sensor and the measured time between the passing of the consecutive magnets; and comparing the calculated distance between the magnets with an original, predefined distance between the magnets.
