A self-propelled flat-bed trolley is provided which includes a motor for locomotion and including a load-bearing platform and an articulated crane with a telescopic arm adapted to load and unload articles to and from the platform. The crane is maneuverable to locate the center-of-mass of the articles within a base of support for the trolley, with the trolley further including a controller for controlling the motor and articulated crane.

A system for extraction of a pool cleaning robot from a pool, the system may include a base for receiving the pool cleaning robot; and at least one out of (a) an interface device and (b) a pool cleaner electrical power cable winding drum; wherein the interfacing device comprises an interfacing device portion that extends beyond and below the base during a part of the extraction of the pool cleaning robot from the pool; and wherein the pool cleaner electrical power cable winding drum is configured to wind and unwind a power cable of the pool cleaning robot during the part of the extraction of the pool cleaning robot from the pool.

Apparatus for use to remove and/or replace cement slat, cement supports in a cement slatted flooring of an animal pen, comprising a manually operable engine driven wheeled vehicle characterized by being supportable on a slotted concrete slat flooring and on the area proximate thereto, an elevated extendible boom pivotably attached to the vehicle at the boom's proximate end and having grasping members at the boom's distal end, a hydraulic device coupled between the vehicle and the boom and between the ends of the boom for pivotally raising and lowering the boom, and manually operable controls for operating the hydraulic device located on the vehicle whereby the vehicle and the boom are manually operable to place the grasping members into the vicinity of a flooring cement slat or a flooring support for attachment thereto to raise the flooring cement slat or flooring support and carry it to an alternate site.

A pool cleaning robot that may include a filtering unit for filtering fluid that passes through the filtering unit; a calorimetric sensor for sensing a cleanliness related parameter of the filtering unit while the pool cleaning robot is submerged in the fluid; and a controller that is configured to at least assist in determining, based on the cleanliness related parameter of the filtering unit, a cleanliness of the filtering unit.

A lifting unit for a vehicle can include a mounting assembly configured to pivotally couple to a lifting boom of the vehicle, a coupler assembly configured to releasably couple with equipment positionable by the lifting unit, and a rotary actuator assembly coupled between the mounting assembly and the coupler assembly. The mounting assembly includes a mount, a travelling frame coupled to the mount, and an extension actuator configured to displace the travelling frame along an extension axis relative to the mount. The rotary actuator assembly is configured to rotate the coupler assembly about a rotational axis.

A pool cleaning robot for cleaning a pool, comprising: a housing; and a drive system that is arranged to move the pool cleaning robot in relation to an environment of the pool cleaning robot; wherein the environment comprises the pool and an exterior surface; wherein the drive system comprises: a drive motor system; a group of interfacing modules; a transmission system that is arranged to couple the drive motor system to the group of interfacing modules; and an interface manipulator; wherein interfacing modules of the group are arranged to interface between the pool cleaning robot and the environment; wherein the interface manipulator is arranged to change a spatial relationship between (a) the housing and (b) a selected interfacing module of the group, during an exit process during which the pool cleaning robot exits the pool.

A crane, particularly a rubber-wheel container crane includes a frame which has, on opposite sides of its lower part, main beam structures at both ends of which, i.e. in the lower corners of the crane, there are two successive rubber wheels or wheel arrangements through which the crane is supported by its moving carrier. These wheels are supported by the main beam structure rigidly and in an unsuspended manner.

The invention relates to a work vehicle (10), particularly, for use in rugged uneven terrain, for example, in agriculture/forestry. The vehicle (10) generally has a chassis frame (24) and a pair of axles (14, 20) longitudinally spaced along the chassis (24), the axles (14, 20) being pivotable in an opposing or opposite fashion about axes (A, D) generally perpendicular to the longitudinal axis of the chassis. The vehicle (10) has a support frame (206) mounted relative to a front axle (14) to be displaceable therewith, in use. The vehicle (10) also has a work apparatus (204) mountable to the support frame (206) and displaceable relative to the vehicle (10) wherein, in use, under control of an operator, the support frame (206) and work apparatus (204) are adapted to rotate with the first axle (14) about the first pivot axis (A).
