A portable tow system includes a drive system for removable mounting to a first anchor point, a flywheel system for removable mounting to a second anchor point distal from the first anchor point, and a tow strap for connecting a drive wheel of the drive system to a flywheel of the flywheel system. One or more persons or objects can be removably attached or connected to the tow strap. The drive system includes a motor for causing the drive wheel to rotate, which rotation causes the tow strap to rotate, such that the person(s) or object(s) connected thereto may be pulled from the first anchor point to the second anchor point or vice versa.

A method of spooling a crane rope (2) onto a crane drum through a crane rope spooling system (1) from a reel (31) under a predetermined back tension is described and includes the steps of: unspooling the crane rope (2) from a reel (31) and passing the crane rope through a tensioning system (10) comprising a primary back tensioner (12) and a secondary back tensioner (16); gripping the crane rope (2) within the secondary back tensioner (16) and thereby preloading the crane rope (2) with tension prior to the crane rope (2) passing through the primary back tensioner (12); and applying a predetermined back tension to the crane rope (2) with the primary back tensioner (12) as the crane rope (2) is being spooled onto the crane drum under the predetermined back tension. A crane rope spooling system (1) for spooling crane rope (2) onto a crane drum under a predetermined back tension is also described, said system (10) comprising a tensioning system (10) comprising at least a primary back tensioner (12) and a secondary back tensioner (16) and a reel (31).

A winch assembly includes a motor, a drum, and a gearbox. The drum extends from the motor to the gearbox. The winch assembly further includes a housing. The drum extends through the housing. The winch assembly further includes a fairlead. The fairlead is directly coupled to a face of the housing and provides structural support for the winch assembly.

Described is a tugboat 1 for assisting a marine vessel 2 to manoeuvre. The tugboat 1 comprises a hull 11 having a perimeter P. The tugboat 1 also comprises a line handling system 10 comprising a line guide mechanism 100. The line guide mechanism 100 protrudes, or is positionable to protrude, away from the hull 11 for guiding a line 20 of the marine vessel 2 towards a predetermined region R of the perimeter P.

A self-retracting tie down winch for tying cargo on a vehicle is provided. The self-retracting tie down winch comprise a frame that can be attached temporarily or permanently to the transport vehicle, a binding system to secure the cargo, the binding system comprising a gear and a unidirectional pawl and driver to insert a binding media. The self-retracting tie down winch further comprises a space to spool the tie down media around the winch shaft, a self-retracting mechanism for the tie down media to self-retract, and a self-retracting mechanism. The self-retracting mechanism can be stopped in a locking state at given length to ensure a tension free tie down media to facilitate its placement. It can be re-engaged from the locking state to rewind the tie down media.

A remote controlled lift assembly includes a pair of supports is each mountable to a respective outrigger of scaffolding. A winch unit is positionable on the supports when the supports are mounted on the scaffolding and the winch unit has a cable extending downwardly therefrom. The cable is lowered or lifted when the winch is actuated. A receiver is coupled to the winch unit and the receiver is in electrical communication with the winch unit. A remote control is provided that is carried by a user and the remote control is in wireless electrical communication with the receiver. In this way the user can remotely lift and lower the cable for lifting and lowering cargo.

A portable pulling device and method therefore, the portable pulling device including a chassis frame, a power source, anchoring elements, a spool, a rope or cable attached thereon, and a centrifugal clutch with a chain or belt drive system allowing the ability to pull out the rope when the power source is at idle. The device further contains frame propulsion components such as wheels, skis, or tracks to facilitate movement of the pulling device into and through a confined area such as a forest or a barren area.

A machine for extracting a ductile pipe. The machine has a vise which can grip the pipe, and a wire clamp. Each of the wire clamp and vise are supported on a carriage which is movable relative to a frame. This enables the vise to grip and pull the ductile pipe. Additionally, a wire strand may be disposed through the pipe from a far end to the end at which the machine is placed. The wire clamp allows the machine to pre-stress the strand to improve the extraction of the ductile pipe.
