An apparatus, system, and related methods for holding and maneuvering an industrial vehicle spare tire include a tire support positioned on an industrial vehicle. An industrial vehicle tire is removably securable to the tire support, wherein the tire support has at least two independently adjustable threaded members for controlling engagement of the tire support and the industrial vehicle tire. A winch is positioned proximate to the gate of the industrial vehicle. At least one pulley is positioned above the tire support, wherein at least one winch cable is connected between the winch and the at least one pulley.

The present invention discloses a super large tonnage detachable hook. The hook comprises: a hook rod, a hook shaft, a hook body, a spherical roller bearing, and a thrust spherical roller bearing. The hook also contains a connection component which connects the hook rod to the hook body. The split-type self-locking sleeve is integrally connected to the hook rod via the hook hoop holder. Meshing of the sleeve with the toothed sleeve of the hook rod is adopted to transmit the load, and the bearing capacity is greatly improved compared with the traditional screw connection. The hook of the present invention can withstand the downward and upward bi-directional load, which solves the problem that the traditional hook is prone to damage once it hits the ground. The hook is forged with 30CrNiMo8, which can lift an extremely large weight of more than 5,000 tons.

The pulley for a block and tackle system includes a shell, a sheave, and a pin. The shell includes a shell pinhole extending through the center of the shell. The sheave includes a sheave pinhole extending the center of the sheave. The pin extends through the shell pinhole and the sheave pinhole, the pin operable to fix a position of the sheave in two directions with respect to the shell. A swivel anchor point is connected to the shell; a hook is connected to the shell and opposite of the swivel anchor. A clasp is fixed to the opening of the hook, in which the hook is operable to connect the pulley to an object, and the clasp comprises wings extending outwardly from the latch.

A hoisting device includes a body, a hoisting rope, a rope drum arranged in connection with the body, on which a first end of the hoisting rope is fastened, and a hoisting part which ascends and descends by means of the hoisting rope. The hoisting device includes a fastening device of a second end of the hoisting rope, which is formed into a loop wherein a spiral groove is substantially surrounding the entire loop and in which the part adjacent to the second end of the hoisting rope is received. The hoisting device further has a fastening arrangement which locks the second end of the hoisting rope to the fastening device, preventing the second end from being pulled out of the fastening device.

Described herein is a hoist fleet system including a head block and a guide fleet assembly. The head block includes a plurality sheaves having more than one diameter. The guide fleet assembly can be arranged proximate the head block such that an array of lift lines can be routed through the plurality of sheaves of the head block into the guide fleet assembly. The guide fleet assembly further includes a plurality of guide sheaves and a plurality of plates. The plurality of plates is configured to house the plurality of guide sheaves. The plurality of guide sheaves is positioned substantially orthogonal to the head block. The plurality of plates is further arranged such that the plurality of guide sheaves is arranged on more than one plane. The plurality of guide sheaves is configured to reduce the spacing of the lift lines.

The hoisting arrangement of a hoist of a of a crane, includes a trolley arranged to move along a main support structure of the crane, whereby the trolley includes a support frame structure; bearing wheels which are fastened to the support frame structure and by means of which the trolley is arranged to move along said main support structure; a hoisting mechanism that has a rope drum for a hoisting rope, a rope pulley arrangement which has upper sheave arrangements and lower rope pulley arrangements and through which the hoisting rope may be guided from the rope drum to an attachment point, and a hoisting member in cooperation with the hoisting rope for hoisting a load; whereby the rope drum is supported to the support frame structure of the trolley so that the axle of the rope drum is parallel to the main support structure. In the hoisting arrangement, the disengagement point of the hoisting rope from the rope drum, the attachment point of the sheave, and the attachment point of the first end of hoisting rope are arranged on the same vertical plane of the hoisting arrangement. The rope drum has a first end towards which the hoisting rope is wound in the hoisting member's upper position, and a second end towards which the hoisting rope is unwound in the hoisting member's lower position. The first rope pulley of the rope pulley arrangement is so placed that the release point of the hoisting rope from the first rope pulley to the first sheave is, in the axle direction of the rope drum, further from the second end than the first end of the rope drum.

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.
