An automatic locking mechanism can include one or more annular elements having teeth facing each other or facing away from each other. The automatic locking mechanism can include a rod disposed between the annular elements. The rod can have one or more pins configured to interface with the teeth of the annular elements. The pins and the teeth are also configured to rotate the rod when the annular elements move relative to the rod. The rotation of the rod can toggle a hook end of the rod in a hook receptacle, which can change states of the locking mechanism.

A device and method for lifting a hollow bodied block includes an elongated body having a top end and a bottom end with a handle attached to the top end. A first arm rigidly extends from the elongated body in a substantially perpendicular direction and is configured to engage an inner surface of the block. A second arm is pivotally attached to the bottom end of the elongated body in a substantially opposite direction to that of the first arm. Upon exerting a lifting force on the handle of the lifter, the second arm rotates relative to the elongated body, forming a desired angle with the first arm and creating an outward force sufficient to grip and lift the block.

A cable grappling assembly for lifting, dragging or otherwise manipulating a cable lying on the ground includes a handle that is elongated to a length of at least 36.0 inches to extend approximately from a user's waist to the ground when the handle is gripped. A grapple is coupled to the handle for engaging a cable lying on the ground without requiring the user to bend over. Moreover, the grapple is curved to engage the cable for lifting and dragging the cable.

In a work assisting apparatus helping workers to lift heavy objects with hands, their work is assisted with a light-weight and simply configured winding device, contributing to cost and load reduction while refraining a belt as a support wire rope from hindering their normal working behavior, or another objects from being caught in or wound around the belt, the work assisting apparatus including: a fitting portion fitted on a torso, a wearing portion worn on an arm or a hand of a worker, a belt with one end portion combined to the wearing portion, and a winding device coupled to the fitting portion and winding another end side of the belt. The winding device includes a lock mechanism locking a draw-out position of the belt so as to restrict further drawing out when drawing the one end portion.
