A fall protection system includes a mast assembly including a fixed mast section, a movable mast section, and a winch assembly. The fall protection system further includes a locking mechanism adapted to lock the movable mast section relative to the fixed mast section. The locking mechanism includes a locking pawl connected to the winch assembly. The locking pawl is adapted to rotate between an engaged position and a disengaged position. The locking pawl engages with the fixed mast section in the engaged position to prevent relative movement between the fixed mast section and the movable mast section. The locking mechanism also includes at least one spring adapted to bias the locking pawl towards the engaged position. Further, the winch assembly is adapted to retain the locking pawl in the disengaged position against the biasing of the at least one spring based on a tension selectively applied by the winch assembly.

Control circuitry for a crane, comprises an input interface (102) configured to receive readings of sensors (174, 520) sensing operating parameters of the crane and an output interface (104) to output control data to cause actuators of the crane to perform a movement. A compute circuit (106) is configured to control the movement of the actuators in a first operation mode and in a second operation mode, wherein at least one kinematic parameter of the actuators is limited in the second mode as compared to the first mode.

Control circuitry for a crane, comprises an input interface configured to receive readings of sensors sensing operating parameters of the crane and an output interface to output control data to cause actuators of the crane to perform a motion. A compute circuit is configured to control the operation of the crane such that a boom system of the crane is automatically transferred from an arbitrary working position to a transport position.

A crane (100) comprises a boom (110) rotatable about a pivot (120) between a crane base (130) and the boom (110) and a winch arrangement (150) mounted movable with respect to the boom (110). A load weighting element (160) is mounted between the boom (110) and the winch arrangement (150).

Control circuitry (110) for a crane (120), comprising an input interface (102) configured to receive readings of sensors sensing operating parameters of the crane (120) and an output interface (104) to output control data to cause actuators of the crane (120) to cause a motion of at least one of a boom (130) of a boom system or a column (160) of the crane (120). A compute circuit (106) is configured to control the operation of a winch arrangement (140, 400) mounted to a boom (130) of the boom system, wherein a position of an attachment reference (150) of a cable (420) of the winch arrangement (140, 400) moves along a defined path during movement of the crane (120).

FIG. 1

Implementations of cranes may include a first telescoping boom and a second telescoping boom coupled within the first telescoping boom. The second telescoping boom may be entirely within the first telescoping boom when the second telescoping boom is in a fully extended position.

A tool cart and ladder hoist system for providing a safe and efficient manner for carrying tools. The tool cart includes a tool compartment, a hoist ring, at least one wheel, and at least one support strap. The tool cart is defined by a pair of side walls, a back wall, a handle portion, and a base. The ladder hoist component includes a winch casing, a removable carrier casing, and at least one fastener pin. The ladder hoist component interacts with the hoist ring to provide a method for lifting tools. The tool cart may also include compartments for carrying and housing various tank components.
