In one embodiment, a roller jack includes: caster wheel attached to jack lift attached to an angle member having an angle member opening, and a locking mechanism to releasably lock the angle member to a corner block of a container through an elongated opening of the corner block. The locking mechanism includes: a locking mechanism baseplate having a baseplate protrusion, a swivel locking plate to be inserted through the angle member opening and the elongated opening of the corner block to the interior of the corner block, and a locking bolt for moving the swivel locking plate to an engaged position, where the swivel locking plate is prevented from passing through the angle member opening and the elongated opening of the corner block, and for threadingly moving the swivel locking plate toward the locking mechanism baseplate to press the angle member and the external wall of the corner block together.

A carrying device (1) for the frontal removal of a roll body from a roll frame, comprising a main frame (2) and a receiving section (3) for the roll body. The receiving section (3) can be transferred from an introduction position (E) into a supporting position (S). The receiving section (3) has a profile which at least partially encloses the roll body in the supporting position (S), and the carrying device (1) can be pushed in below the roll body with the receiving section (3) in the introduction position (E), and the roll body is carried with the receiving section (3) in the supporting position (S).

A floor service jack includes a battery and a control panel provided at a distal end of a handle of the jack for electro-mechanically or hydraulically controlling a lift arm to raise and lower a vehicle for servicing without exposure to an undercarriage of the vehicle to replace the battery or to operate the control panel.

A carrying mobile robot includes a frame, a suspension system disposed at the bottom of the frame, and a lifting mechanism disposed on the frame. The suspension system includes two suspension mechanisms disposed on the left and right sides, each of which includes a supporting beam, a driving wheel, a connecting member and a first driven wheel. The first driven wheel and the driving wheel respectively support the front and rear ends of the supporting beam, and the connecting member is connected to the supporting beam and located between the driving wheel and the first driven wheels. The lifting mechanism includes a plurality of lifting members, a first driving system for driving the lifting member and a transmission system for transmitting the driving force of the first drive system to the lifting members.

A handle assembly including an elongate handle having an inner end, an outer end, and a length between the inner end and the outer end, and a multipart cover including an inner cover, and an outer cover. The inner cover is fitted removably over the length of the handle, the outer cover is fitted removably over the inner cover, the inner cover and the outer cover concurrently encircle and extend along the length of the handle from proximate to the inner end of the handle to proximate to the outer end of the handle, and the outer cover includes a chemically-resistant exterior gripping surface.

Method and apparatus for improved height adjustment of wall partitions. According to the present disclosure, an extendable Foot Controlled Elevator Device is placed beneath a wall partition. A user may then apply downward force on a Vertical Height Control to adjust the vertical position of the wall partition. In some embodiments, the Foot Controlled Elevator Device has a compressible base, allowing it to fit into tight areas (e.g., between toilets in a restroom under construction). In other embodiments, one or more Foot Controlled Elevator Devices may be linked, allowing for better control over the wall divider and simultaneous or distinct control of the respective Foot Controlled Elevator Devices.

The presently disclosed Lifter comprises a substantially level horizontal, partially or totally tracked, overhanging bar, which is supported by the roof of a vehicle. The tracked bar is held up against the upper door frames by a ratcheted strap over the roof and in between two open doors on each side of the vehicle. Another ratchet attached to the bar via a trolley is usable for lifting the object, and the trolley allows for its horizontal movement along the tracked bar. Particularly, the object may be an incapacitated person such as a patient. Even more particularly, the patient may be held and restrained in harness-type garment comprising a lifting loop. Generally, the Lifter may be used to lift any heavy object in and out of a vehicle using mechanical leverage. In some embodiments, the bar comprises two shorter C channels removably joined, or a shorter channel with a telescoping extension. Thus, the presently disclosed lifter is very easy to carry, store, and generally handle as an auto accessory.
