A support assembly including a coupler, a first arm having a proximate end movably coupled to the coupler, a distal end opposite the proximate end, and a second arm having a proximate end movably coupled to the coupler, a distal end opposite the proximate end. The support assembly is movable between a disengaged position and an engaged position. When moving from the disengaged position to the engaged position, the distal end of the first arm and the distal end of the second arm move toward each other.

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 container spreader for coupling a container with a hoisting installation has a number of assemblies of a guiding plate and a displacing device connected thereto, for displacing the guiding plate between an active position A and an inactive position B. The displacement device has a hydraulic swivel motor provided with an output shaft which is connected to the guide plate via connecting elements. A hydraulic unit is coupled to the swivel motor via coupling device for supplying and discharging hydraulic oil from and to the swivel motor. By applying a hydraulic swivel motor, a final transmission can be omitted and no valves are required for keeping the hydraulic motor at pressure. As a result, an energy-efficient and inexpensive assembly has been obtained.

A clutch for lifting a concrete component, including a toroidal connector, a latch movable relative to the toroidal connector between a disengaged condition and an engaged condition, and a coupler for coupling the toroidal connector to a lifting apparatus, wherein the coupler includes a first part and a second part pivotal relative to the first part about a pin, and wherein the coupler includes a tamper evident indicator to indicate that the clutch has not been disassembled.
