A height-adjustable table including a length-adjustable support, a motor assembly configured to drive adjustment of the length-adjustable support, a motor housing supporting the motor assembly. The length-adjustable support includes a telescopic column assembly comprising an exterior tube, an interior tube, and a spindle assembly. The spindle assembly includes spindle rod fixedly coupled to a first end of the exterior tube, the spindle rod being threadingly engaged with a spindle guide coupled to a first end of the interior tube, whereby rotation of the spindle rod causes the distance between the first ends to change in order to telescope the interior tube into or out of the exterior tube. Illustratively, force from rotation of the spindle rod is transferred through the spindle guide and into the first end of the interior tube. In illustrative embodiments, the spindle guide may extend through an aperture of a support plate coupled to the first end of the interior tube, thereby permitting transfer of force from the spindle rod to the interior tube.

A workstation includes a partition unit to form a workspace, in which a desk board, two lifting apparatuses and a driving device are provided. Each of the lifting apparatuses has a first tubular member connected to a bottom of the desk board, a second tubular member fixed to the partition unit, and a lifting device to move the first tubular member relative to the second tubular member. The driving device is connected to the lifting devices to drive the lifting devices to move the first tubular members so as to lift and lower the desk board.

Disclosed is a desktop lifting platform with improved safety, which relates to an electric lifting platform equipment. The desktop lifting platform includes a lifting column, a desktop, a base, a controller, and a manipulator, wherein the base is placed on a work platform like a desk; the lifting column includes a drive motor; the controller includes a main control unit (MCU) and a motor-driving circuit, the output end of the MCU is connected to the motor-driving circuit; the desktop lifting platform includes a sensing unit adaptable for detecting or sensing whether the desktop lifting platform hits an obstacle or tilts, such that when sensing that the desktop lifting platform hits the obstacle or the tilts, the sensing unit emits a signal to the controller for controlling the lifting column to stop lifting.

The invention relates to a supporting frame with a lifting column (59) comprising telescopically arranged profiles with an upper and lower end, said upper end having a housing (60) secured thereto, and a base unit (61,62,63) with a compartment at least for partial reception of the lifting column housing (60) and a locking element (75), which when placed in a locked position exerts a squeezing force between the base unit (61,62) and the housing (60) of the lifting column (59). Thus, the housing (60) of the lifting column (59) is positioned and fixed in the base unit (61,62,63). The supporting frame further comprises means for retaining the locking element (78) in the locked position.
