Disclosed is a filler piece mounting assembly for a lifting column. The lifting column includes a first casing and a second casing sliding in the first casing. The filler piece mounting assembly includes a resilient filler piece and a fixed frame for fixing the resilient filler piece. The resilient filler piece is disposed outside an outer wall of the second casing and axially fixed relative to the first casing. The fixed frame is disposed at a front end of the first casing and moves relative to the first casing. A first inclined surface is disposed on an outside of the resilient filler piece. The fixed frame includes an extrusion part for extruding the first inclined surface, and the extrusion part extrudes the first inclined surface to radially deform the resilient filler piece to adjust a clearance between the resilient filler piece and the second casing.

A radial-scissor lift assembly for a table top comprising an upper support member, a lower support member, and at least three scissor assemblies coupled to the upper and lower support members. Each scissor assembly includes a table-scissor member rotatably supporting a table wheel adapted for contacting an unattached table. Each scissor assembly further includes a floor-scissor member rotatably supporting a floor wheel adapted for contacting a surface supporting the radial-scissor lift assembly. The radial-scissor lift assembly has an actuator assembly coupled to the lower support member and to the upper support member for moving the scissor assemblies. A method for lowering a table top comprising disposing a table top on at least three table rollers, and rolling the table rollers along the bottom on the table top and away from the center of the table top to cause the table top to be lowered.

A lifting table stand includes a pair of telescopic columns, a carrier, an actuation module, and a passive mechanism. Each telescopic column includes multiple tubes adapted to sheathe with each other and move telescopically relative to each other. The carrier includes a beam straddling the telescopic columns and a pair of support members perpendicularly connected to two ends of the beam. The actuation module includes a receiving member detachably installed to the beam and a driver connected to the receiving member. The passive mechanism includes a transmission shaft and a pair of gear sets installed in the tubes. The transmission shaft passes the driver and is connected to each gear set. Since the receiving member is detachably installed to beam, the actuation module may be changed to different types to control the elevation of the lifting table stand.

A device for adjusting the height of a first part relative to a second part includes a first hollow profiled element, a second hollow profiled element which is displaceable along its longitudinal axis relative to the first hollow profiled element, a drive unit for displacement of the second hollow profiled element relative to the first hollow profiled element and a support unit which, in relation to the longitudinal axis, is arranged between the first hollow profiled element and the second hollow profiled element for the purpose of supporting the first hollow profiled element against the second hollow profiled element.

A tool cabinet includes a cabinet body having two guide rails, a working platform unit having a movable platform member and two hollow extension members, two lifting units each having a threaded rod, two driving units, and a control unit. The extension members are respectively slidable relative to the guide rails. The threaded rods respectively extend through the extension members and telescopically into the guide tubes. Each driving unit has a motor, and a speed reduction mechanism driven to rotate the threaded rod of a respective lifting unit. The control unit is connected to the motors for synchronizing movements of the motors.

Aspects of dynamic workstation apparatus, methods, and systems are disclosed. One aspect disclosed herein is a workstation apparatus that includes a frame including overhead frame elements defining a covered workspace. The apparatus also includes a raiseable and lowerable work surface that may be configured to be movably attached to the overhead frame elements and may be selectively positionable in the covered workspace at a plurality of different vertical heights including a standing height and a floor height. A first actuator may be attached to and operable with the frame to move the raiseable and lowerable work surface between a range of movement including the standing height and the floor height while maintaining an orientation of the raiseable and lowerable work surface relative to the frame such that the raiseable and lowerable work surface may remain relatively level. Aspects of related methods and systems also are disclosed herein.
