A carrier building ladder hoist that contains a removable carrier casing and a winch casing allowing a user to hoist items. The ladder hoist contains a padded back and straps to allow an individual to carry it on their back and wheels and a tow handle to allow the user to tow it behind them. The side surfaces of the winch casing in ladder hoist have grooves in them to allow a user to hook the ladder hoist to a ladder. The ladder hoist has a winch system using gears and a winch strap ending in a hook.

A line guidance device (40) is provided for use with a confined space entry/retrieval hoist and fall protection anchorage system (10) and includes a line guide (46) that guides a line from an extend/retract line device (22) past another extend/retract line device (20) with both devices (20, 22) mounted on a backside (24) of a mast (12) of the system (10).

An overhead storage device or system may include a mechanism for hoisting the object to be stored (e.g., a bicycle) at an elevated height (e.g., above grade or floor level). In general, the present teachings may include a cable pulley engaged with a constant torque spring unit structurally configured to apply an approximately constant torque to the cable spool that promotes rotation of a spool thereof for winding of a lift cable about the spool to lift a load. Also disclosed are techniques for improving such a constant toque lifting unit such as an inertial brake structurally configured to slow down or stop an undesired, accelerated winding of a lift cable, a self-coiling device structurally configured to advantageously wind the lift cable a predetermined amount (e.g., for removal of same as a hinderance), and an attachment mechanism structurally configured to securely couple to a load.

Provided is an improved come along device with a handle, a release trigger for a stop pawl, and a push tab for a release pawl. The handle may allow an operator to better grasp the come along device. The release trigger allows an operator to release tension in a cable by disengaging the stop pawl when the trigger is pulled and engaging the stop pawl when the trigger is released. The push tab allows an operator to disengage the release pawl when the push tab is pressed and engage the release pawl when the push tab is pulled.

An article of manufacture for providing an earth extraction device provides a set of three posts, a post securing bolt having a threaded end and a fix end and passing through the first top hole and the second top hole of each of the three posts in consecutive order for coupling the set of three posts together at a coupling point, a mating nut for coupling to the threaded end of the post securing bolt after protruding through the second top hole of the third post, a block and tackle pully-and-winch, and a top chain having a first end and a second end, the top chain configured around each of the posts of the set of three post above the coupling point. The block and tackle pully-and-winch includes a hook coupled to a top end, a winch cable configured within the pully and winch; a bottom chain coupled to a bottom end, and a winch handle, the winch handle configured to rotate the winch causing the winch cable within the block and tackle to shorten with an upward stroke. The first end and the second end of the top chain engaging the hook to suspend the pully and winch below the coupling point of the set of three posts.

A winch assembly (50) including: a winch shaft (12) rotatably mounted within a bracket (18) and adapted for rotation about a first axis (68); a substantially right-angled drive transferring mechanism having a drive input coupled to a manual tool engagement device and drive output coupled to the winch shaft (12), the tool engagement device adapted for rotation about a second axis (72) extending substantially radially from the first axis (68), wherein manual rotation of the tool engagement device causes rotation of the winch shaft (12); and an anti-twist bar (64) attached to the bracket (18) to reduce twist during rotation of the winch shaft (12).

A mast raising assembly includes a base that is securable to a horizontal support surface. A tube is insertable into the base such that the tube is vertically oriented. A winch is coupled to the tube and a pair of lower pulleys is each rotatably coupled to the tube. A mast is pivotally coupled to the tube. The mast is positionable in a raised position and a folded position. A plurality of upper pulleys is each of the upper pulleys is rotatably coupled to the mast. A cable extends between the winch, the lower pulleys and the upper pulleys. The cable urges the mast into the raised position when the winch is rotated in a raising direction. Additionally, the cable urges the mast into the folded position when the winch is rotated in a lowering direction.
