A compact telescoping lift arm assembly includes an outer arm section pivotally connected by a pivot member to a lift carriage vertically slidable on a post and an inner arm section telescopically received within the outer arm section and movable in and out of the outer arm section. The inner arm section has a nesting slot formed at an inner end thereof to nest about the pivot member when the inner arm section is retracted into the outer arm section.

The disclosure provides a core-pulling transfer device for reverse demolition of reinforced concrete structures and a construction method. The device comprises temporary supports, long-stroke hydraulic jacks and steel crossbeams, wherein the temporary supports are supported on bottom surfaces of bottom crossbeams of the reinforced concrete structure, 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, both ends of each steel crossbeam extend out of the corresponding core-pulling hole, lower surfaces of the long-stroke hydraulic jacks are fixedly connected to a foundation, and upper surfaces of oil cylinders of the long-stroke hydraulic jacks are propped against lower surfaces of the corresponding steel crossbeams after moving up and penetrating through the corresponding beam end through holes. The disclosure can quickly carry out vertical load transfer of the reinforced concrete structure, smoothly transfer vertical force, and achieve a safe reverse demolition construction process.

The invention relates to a lifting system for lifting a load, such as a vehicle, and a method for lifting a load. The lifting system includes: one or more lifting devices; a group controller arranged to operate the lifting devices; and a user interface unit including a transmitter and/or receiver configured for communication with the group controller, a processor, a display device, and input means configuring the user interface unit to receive user input. The user interface unit is adapted to communicate command signals to the group controller on basis of the user input and adapted to receive and display information obtained from the group controller. The lifting system includes a network interface unit including a network transmitter and/or network receiver configured for communication to an external network.

Described is a device for lifting an object from a deck of a vessel subject to movements in a heave direction. The device comprises a support surface (6a) for the object provided at a first height (11) in the heave direction relative to the deck. A lifting crane (5) is configured to take up the object from the support surface (6a) at a lifting point thereof at a lifting speed. An actuator system (16) is configured to lower the support surface (6a) relative to the deck at the instant in time at which the object is lifted from the surface to a second height in the heave direction at a lowering speed. A method using the device is also described.

An apparatus includes a housing, a piston, an input cavity, a first actuating shaft, a first output cavity, and a second output cavity. The housing comprises an input port, a first output port, a second output port, a first end, a second end, a first wide wall having a first internal surface, and a chamber at least partially defined by the first end and the first internal surface. The piston is able to actuate along the first internal surface of the first side wall. The input cavity is in fluid communication with the input port. The first output cavity is in fluid communication with the first output port. The second output cavity is in fluid communication with the second output port. The first actuating shaft is fixed to the piston and helps fluidly isolate the first output port from the second output port.

A gantry crane adapter for a two-post lift includes a pair of angle brackets, each of which has a first, horizontal leg and second, vertical leg. The first leg includes an aperture, and a short hook extends in parallel, spaced relation along an outer surface of the second leg. The hook of each bracket is received in the slot in a carriage in a respective post of the two-post lift to removably connect each bracket to the respective carriage, with the first, horizontal legs of the respective brackets projecting toward each other. A load bearing beam is positioned across the brackets such that an internally threaded boss at each end of the beam is received in an aperture in a respective bracket, and a bolt with a washer is threaded down into the boss, to support and retain the load bearing beam across the angle brackets.
