A pool cleaning robot for cleaning a pool that may include a filtering unit; a housing; an impeller; a pump motor for rotating the impeller; a drive system; and an interface for coupling an extraction element to the pool cleaning robot, during a pool exit process; and wherein during at least a part of the pool exit process an upper end of the interface is higher than the housing.

A fairlead for use with a winch is disclosed. The fairlead includes: a self-reversing screw; a motor for driving the self-reversing screw; and a guide comprising a guide nut and a first guide side and a second guide side. The guide is driven by the self-reversing screw. As a line is coiled onto a winch drum the guide directs the line onto the winch drum. The first guide side and second guide side are detachable from the guide nut and from each other.

A cable puller and associated methods are shown. Useful example methods include pipe bursting using cable pullers as shown. Cable pullers and methods shown provide a mechanical advantage that increases an amount of cable pulled in one cycle. Selected examples are shown that include a pulley located on a distal end of a moving portion of an extending and contracting beam. The pulley and the mechanical advantage it supplies helps to improve the efficiency of the cable puller and reduce manufacturing cost of the cable puller.

A device configured for attachment to a loop end of a recovery winch rope or cable includes a hood element configured to fit over and around the loop end of the recovery winch rope or cable, wherein the hood element covers outward facing surfaces of the loop end, orifices located on either side of the hood element and aligned with an opening in the loop end, such that a continuous open space extends through the opening of the loop end, a base coupled to the hood element, the base being sized to prevent passage through a fairlead of the recovery winch, a removable cap located in the base, wherein the cap includes a space that allows the rope or cable to extend therethrough, and, wherein the hood element, the base and cap are composed of an elastomeric polymer.

A fairlead for use with a winch is disclosed. The fairlead includes: a device for detecting a speed at which a line is being spooled or unspooled from the winch, a first and second roller adapted to aid in spooling or unspooling a line, a fairlead motor for driving at least the first roller, and a controller connected to the fairlead motor. The controller is in communication with the device for detecting the speed. The controller is configured to direct the fairlead motor to drive at least the first roller at a speed that maintains tension on the line as it is unspooling or spooling. Alternatively, the device measures current drawn by the fairlead motor and the controller directs the fairlead motor to drive the rollers at a speed that maintains a target current draw.

A wire pulling windier apparatus attachable to a tractor, loader or other mobile transport device capable of receiving attachments has a pass through frame attachable to the mobile device, a vertical support member on the frame for supporting a first winch with cable for attaching and pulling a fence wire to be tensioned, a second winch for raising and lowering a slide block assembly through which the first winch cable is guided to allow pulling the first winch cable at different vertical heights, and has winch tension limiting apparatus.

A removably attachable rear loader attachment mechanism for attaching to a standard stock rear end refuse collection vehicle body, the removably attachable rear loader attachment including a pair of latch assemblies removably attachable to flanges associated with the rear end portion of the vehicle body, a hopper extension member removably attachable to the rear end portion of the vehicle body, a roller bar assembly having a pair of roller bar frame members each removably attachable to the respective removably attachable latch assemblies, and a hydraulic source attachable to the latch assemblies and to the roller bar assembly for moving such members for capturing and dumping a commercial container into the storage compartment of the refuse collection vehicle. A removably attachable winch mechanism is also removably attachable to the top portion of a standard stock rear end refuse collection vehicle body for aiding in the dumping of a commercial container.

A method for monitoring a cable of an implement system. The implement system includes a drilling device, a tensioning device and the cable, the cable coupled to the drilling device and the tensioning device in a taut configuration to define a first length. The method includes determining, by a controller, an increment in the first length of the cable. The method further includes comparing, by the controller, the increment in the first length with a threshold value; and generating, by the controller, a warning signal if magnitude of the increment is greater than the threshold value.
