A method for supporting and weighing a shipping container, the method including the steps of: providing a shipping container having a corner casting (20); providing a twistlock (30); locating the shipping container such that the twistlock (30) is engaged with the corner casting (20); locating a lifting device (2) inside the corner casting (20), the lifting device (1) having a pair of jaws (3, 4) and an actuator (5); moving the pair of jaws (3, 4) apart using the actuator (5) from a first position to a second position to lift the shipping container relative to the twistlock (30), wherein in the second position the jaws (3, 4) support at least a portion of the weight of the shipping container, and wherein the shipping container remains substantially engaged with the twistlock (30) in the second position; locating a weighing device (10) between the shipping container and the twistlock (30); and moving the pair of jaws (3, 4) from the second position to the first position to apply a force to the weighing device (10), the weighing device (10) providing an indication of the force applied to the weighing device (10).

Jack units attach skates to an object to be moved. Each jack unit has a tongue that slidably engages a coupling slot affixed to the object, and can be operated to raise or lower the tongue; when raised, the object is supported on the skates and can be rolled to a new location. A crane can attach to lift eyes on the jack units to allow the system to be lifted with the skates attached to the object, avoiding the risk to operators of positioning the skates under the object while it is suspended. Rotation-limiting structures can be selectively employed to block rotation of the trailing skates to facilitate steering when rolling the object supported by the system. The coupling slots can be provided in coupling elements which can attach directly to the object or which can be employed to form a freestanding frame to which the object is secured.

A low-impact and modular mobile fuel delivery apparatus is disclosed with a self-propelled unit, a pump unit, and a tank unit. The self-propelled unit is adapted to minimally impact the terrain over which it travels and includes a lift for carrying the pump unit and for moving the pump unit between first and second heights. The pump unit includes a pump for drawing fuel from the tank unit and for supplying fuel to a retractable fuel-delivery hose.

The present invention is a cantilever displacement cargo carrier with an adjustable bearing slide. It has a beam with a first end and a second end, where the first end comprises a cantilever displacement housing with a pivot hole. The carrier has a pivot beam with a first end having a pivot bushing and a slide compartment where an upper adjustable bearing slide is in contact with a lower adjustable bearing slide. The upper adjustable bearing slide has two pin saddles and the lower adjustable bearing slide has a threaded adjusting bolt receiver. A horizontal bearing pin with a plurality of roller bearings is inserted into the two pin saddles. An adjusting bolt is inserted into the threaded adjusting bolt receiver. A pivot pin is inserted into the pivot hole and the pivot bushing.

A core-pulling transfer device for reverse demolition of reinforced concrete structures comprises temporary supports, long-stroke hydraulic jacks and steel crossbeams. The temporary supports are supported on bottom surfaces of bottom crossbeams of the reinforced concrete structure, and a beam end through hole is formed in each end, connected with a force-transmitting structure column, of each bottom crossbeam. Two long-stroke hydraulic jacks are symmetrically arranged on both sides of each force-transmitting structure column. Core-pulling holes are formed in upper end sides of demolition floor structure columns. One steel crossbeam is in clearance fit with each core-pulling hole, and both ends of each steel crossbeam extend out of the corresponding core-pulling hole. The device can quickly carry out vertical load transfer of the reinforced concrete structure, smoothly transfer vertical force, and achieve a safe reverse demolition construction process.

A vehicle lift system includes a plurality of lift groups, each lift group including a plurality of lift columns configured to lift a vehicle and a control device. The system further includes a linker module comprising a processor and a memory, wherein the memory is encoded with programming instructions executable by the processor to receive at least one user command from the control device of at least one of the plurality of lift groups, poll the control device of each lift group in the plurality of lift groups, determine, based on the polling, whether the received command can be executed, responsive to determining that the received command can be executed, send a custom instruction to each lift group to execute the received command, and responsive to determining that the received command cannot be executed, provide a notification to the user.
