PORTABLE WINCH
20210078841 · 2021-03-18 ·

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.

Low-construction trolley for wire rope hoist

A low-construction trolley for a wire rope hoist is arranged to travel along a lower flange of a horizontal rail, on both longitudinal edges thereof. The trolley includes a trolley frame; bearing wheels that are attached to the trolley frame and arranged to travel on an upper surface of the lower flange of the rail; a hoisting mechanism including a rope drum for a hoisting rope, a hoisting member in cooperation with the hoisting rope for hoisting a load, a hoisting motor for driving the rope drum, and a gear to interconnect the hoisting motor and the rope drum; whereby the rope drum is supported to one side of the trolley frame and the hoisting member is arranged to travel under the rail in a vertical plane (A) passing substantially through the middle of the beam. For balancing the trolley without using a counterweight, the hoisting motor is placed under the rail and at least partly on a different side than the rope drum in relation to a vertical plane (B) passing through contact lines of the bearing wheels that touch the lower flange of the rail on the rope drum side.

TENSIONING SYSTEM
20210061160 · 2021-03-04 ·

An improved tensioning system and method of restraining cargo is provided. The tensioning system is easy and quick to operate. The tensioning system is compact and minimises space within a cargo bay. The tensioning system allows a greater angular displacement of a tensioning line over conventional tensioning system, such as a ratchet and strap mechanism.

Mooring assembly for a floating vessel
10926841 · 2021-02-23 · ·

A mooring arrangement for a floating device includes a band and a drum adapted to pay out and pull in the band. The mooring arrangement includes a band guide, the band is extending from the drum via the band guide and is adapted to be coupled to an anchoring arrangement, the band guide being configured to tilt about an articulation axis being parallel with a longitudinal axis of the part of the band situated between the drum and the band guide in order to position the band to compensate for movement in the floating device and thus reduce the wear in the band.

Hoisting arrangement of rope hoist
10926982 · 2021-02-23 · ·

A hoisting arrangement of a rope hoist includes a hoisting rope, a rope drum with one rope groove for the hoisting rope, and a hoisting member for hoisting a load. The hoisting member includes a rope pulley arrangement for the hoisting rope. The hoisting rope is routed from the rope drum via at least the hoisting member's rope pulley arrangement to a fixed attachment point on the rope hoist. The rope drum is tilted in relation to the horizontal plane in a manner where the first end of the rope drum, towards which the hoisting rope is wound in the hoisting member's upper position, is higher than the rope drum's second end, towards which the hoisting rope is unwound in the hoisting member's lower position.
