A tower for a pipe laying system comprises a frame with a leg to support the frame, and a winch support integrally formed with the leg. The winch support is able to receive and support a winch and/or winch components. The winch support can be formed in a lower portion of the tower leg.

A method for a winch system includes receiving, from a controller, instructions to spool a payload line, the payload line comprising a first end and a second end, the first end coupled to a main reel of the winch system and the second end configured to couple to a payload. The method further includes operating, based on the instructions, one or more of a first motor of the winch system and a second motor of the winch system, wherein the one or more of the first motor and the second motor are operated in order to control a position of the second end of the payload line.

The present disclosure presents a webbing take-up device, which comprises: a spool; a lock section that is restricted from rotating at a time of a vehicle emergency so as to limit rotation of the spool in the pull-out direction; a force limiter mechanism that permits rotation of the spool in the pull-out direction at a force limiter load or greater when rotation of the spool in the pull-out direction with respect to the lock section is being limited; a switching member that switches a load value of the force limiter load by switching between a rotation-restricted state and a rotation-enabled state; and a mounting member that includes a switching member mounting section at which the switching member is disposed, and a restriction section that is engaged with the switching member so as to restrict displacement of the switching member disposed at the switching member mounting section.

A hitch mount for a hoist including a main member having a proximal end and a distal end, the proximal end configured to couple with a vehicle hitch, a hoist mounting bracket at the distal end of the main member, a pulley mounted on the main member between the proximal end and the distal end, and a rope lock mounted on the main member between the pulley and the distal end.

A portable winch and method of use is shown. One advantage of winches shown includes an ability to lower a boom or boom sections into limited access exit pit for winching operations such as pipe bursting. Sectional boom designs shown provide the ability to easily raise and lower a boom large distances without the need for a single long boom. Selected winch designs shown include flexible inserts between the boom and the winch frame that help resist damage from unforeseen shifting of the device during operation. Designs and methods shown also include multiple pulleys on a boom end unit. Fasteners are shown that reduce build up of debris.

A method for handling a load (2) including a wind turbine component (202). The method includes, while a crane (1) is supported by a supporting element (G), arranging a control arrangement (501, 502), which is at least partly elongated and flexible, so as to extend, while the load (2) is lifted in a suspended manner with the crane (1), from the load (2) to an actuator (511, 512), located on the supporting element (G), at a distance from the crane (1). The actuator (511, 512) controls the orientation of the load (2) by the control arrangement (501, 502), and the control arrangement (501, 502) is extended, during the load orientation control, via a redirection device (531, 532) which is connected to the supporting element (G).

A propulsion unit includes a platform, a propulsion assembly, and a tether. The propulsion assembly facilitates selective launching of a tire deflation device from the platform. The tether is coupled to the platform and is configured for attachment to a deflation device.

A removable winch handle assembly for engaging a winch gear within a gearbox comprises: a handle receiver having at least a portion thereof exposed outside the gearbox, a seal between the handle receiver and the gear box, an engagement mechanism in the gearbox, the engagement mechanism coupled to the handle receiver to rotate with the handle receiver, wherein rotation of the engagement mechanism engages the winch gear, and a winch handle selectively coupled to the handle receiver, wherein, rotation of the winch handle causes rotation of the handle receiver when attached, the winch handle detachable from the handle receiver, wherein the gearbox opening is sealed by the seal when the winch handle is detached from the handle receiver.

Apparatuses for controlling payload descent are described herein. For example, in one embodiment, a puck is provided that includes a top planar surface, a bottom planar surface opposite the top planar surface and an inner peripheral surface that is substantially perpendicular to the top planar surface and the bottom planar surface. The inner peripheral surface, the top planar surface and the bottom planar surface define a centrally located bore that is substantially perpendicular to the top planar surface and the bottom planar surface. Puck teeth are located on the inner peripheral surface. An outer peripheral surface bounds the top planar surface and the bottom planar surface. An exit port surface is substantially perpendicular to the top planar surface and the bottom planar surface. The exit port surface is between the inner peripheral surface and the outer peripheral surface and couples the top planar surface to the bottom planar surface.
