An installation cart is provided. The cart includes a hydraulic pump that when activated permits a load placed in a lifting cradle of the cart to be vertically raised and/or lowered on the cart. The cart is does not require electrical or gas power for operation and can raise and lower loads placed in the cart for transport weighing in excess of 800 pounds. In an embodiment, the cart includes a clamping mechanism that adjustably allows a load placed in the cradle to be stabilized during transport of the load.

The present inventions provides a lifting device 101 comprising a main body 105 being of a generally elongate form, said main body 105 having at one end thereof a transport means 102, 120 to allow said device to translate relative to the ground, a boom portion 103 cooperating with said main body 105 and adapted to support a load at its end, a motive power means 115 to lift or lower said load, said main body 105 being able to be pivoted by a user with respect to a fulcrum 102, 120 formed by either said transport means 102, 120 and a ground location or said transport means 102,120, around an axis generally parallel to the ground, to transfer or arcuately move a load carried by said boom portion 103, thereby providing a functionally variable horizontal reach 1013 to said device 101.

A crane for lifting and transporting loads includes a base frame, capable of transferring loads onto a support surface. A sliding element is slidably constrained to the base frame. An arm capable of moving the loads is hinged to the sliding element. A connection element has a first end hinged to the sliding element, and a second end constrained to the base frame in a mobile manner. Each of a pair of rod elements is hinged to the base frame and to the connection element to form an articulated quadrilateral. A first linear actuator is hinged to the base frame and to the connection element and to cause sliding movement of the sliding element relative to the base frame. A second linear actuator is hinged to the sliding element and to the arm to cause mutual rotation movement between the arm and the sliding element.

A kit that may include an interfacing device that includes pool sidewall interface, and a pool cleaning robot that includes a housing and a drive system. The drive system may include a drive motor system, a group of interfacing modules and a transmission system that is arranged to mechanically couple the drive motor system to the group of interfacing modules. At least one interfacing module of the group may include protuberances that are shaped to fit a non-smooth surface of the pool sidewall interface.

A cabinet includes a crane including an attachment board secured to the cabinet; a receptacle on the attachment board and including threaded holes; a hollow member on the attachment board; an outrigger on bottom of the attachment board and including a slot, a rear sliding tube, a caster mounted to a bottom of a rear end of the sliding tube, and a rod releasably secured to the sliding tube and in the slot; a boom having one end pivotably secured to the hollow member and including threaded holes, an extension extending from the other end and threadedly secured to the boom, a chain at an end of the extension, and two guard members a front portion of the boom; and an adjustable boom hoist having one end releasably secured to the threaded hole of the boom and the other end releasably secured to the threaded hole of the receptacle.

Overhead lifts with control systems are disclosed. The overhead lifts may include a lift actuator communicatively coupled to a control system. The control system may include a control unit comprising a processor and a memory having computer readable and executable instructions and at least one port for communicatively coupling the control unit to at least one of a computer, a network, and a data storage device. The processor executes the computer readable and executable instructions to: determine at least one operating characteristic of the overhead lift and an operating time of the overhead lift as the overhead lift is actuated; determine an accumulated load-time parameter for the overhead lift based on the at least one operating characteristic and the operating time; and provide an indication that a component of the overhead lift requires service based on the comparison of the accumulated load-time parameter to a service constant.
