A system comprising a crane and an exchangeable tool. The crane and the tool respectively comprise an upper tool connector with tool retainers and a lower tool connector which can be interconnected, e.g. a male and female connector, e.g. the lower tool connector of the tool being embodied as a shank provided with a shoulder and the upper tool connector as a tool clamp with a female, open-centered body. A tool suspension device comprises the upper tool connector. a travelling block member. The tool clamp has multiple mobile tool retainers adapted toin a non-operative positionallow introduction of the shank of the tool from below into the shank receiving passage andin an operative positionengage below the shoulder of the shank that has been introduced into the passage so as to suspend the tool. The upper tool connector may comprise a bearing allowing for swivelling of the open-centered body, and e.g. a rotational drive operative between the clamp housing and the female, open-centered body to actively drive said swivelling.

A vehicle including a vehicle frame with an upper frame edge, a front axle with one front wheel, a rear axle with a rear wheel and a cryogenic container arranged laterally of the vehicle frame, and the cryogenic container is arranged in an installation space available, and a connection line runs to the cryogenic container or to an operating component of the cryogenic container located in the installation space through one of the following spandrels outside of the installation space available: through a rear wheel spandrel between the installation space and the rear wheel; through a front wheel spandrel between the installation space and the front wheel; through a lower construction spandrel between the installation space and an extruded triangle above the road; or, through a semi-trailer spandrel between the installation space and a pivoting region of a semi-trailer mounted on the vehicle.

A reeving device for attaching to an end termination of a hoist rope. The reeving device includes a body with a pair of opposing ends, a central portion, and a tapered portion extending from one of the pair of opposing ends to the central portion. The body defines a cavity extending into the central portion, the tapered portion, and at least one of the pair of opposing ends. The cavity is configured to receive the end termination of the hoist rope. A tether is attached to one of the pair of opposing ends, which facilitates pulling the hoist rope using the reeving device. Related methods are also disclosed.

The present disclosure relates to a boom arrangement and a personnel hoist, and associated method of use. The boom arrangement includes a boom, a man cage, a pivoting frame connected to the boom, a base for supporting the arrangement and a turning joint for turning the pivoting frame. A mechanical parting joint allows the boom arrangement to be divided into two boom units. The parting joint is located in a section between a lower end of the boom and the base, and the parting joint is separate from the turning joint.

A kit of portable modular components for use in demountably configuring a variety of structural assemblies. The kit comprises three types of elongate structural support components wherein the first type has a pair of opposed male ends, the second type has a male end and an opposed female end, and the third type has a pair of opposed female ends, wherein the male ends are configured for demountable engagement with the female ends. Each of the male ends comprises a cylindrical body with at least one linear set of two spaced-apart prongs around the circumferential surface of the cylindrical body. Each of the female ends has a cylindrical receptacle with one or more linear channels for receiving therein the cylindrical body and the at least one linear set of prongs. The female ends are provided with locking assemblies for releasable engagement the male ends.

Disclosed is a winch control apparatus for a crane, which comprises: a first compensation torque value calculation section which calculates, when a hoisting manipulation being input, based on a difference speed between a detected rotational speed and a target speed according to a manipulation amount of the hoisting manipulation, a first compensation torque value for enabling an electric motor to generate a reverse-rotation-preventing torque which is a torque in a hoisting direction and corresponding to the difference speed; and a second compensation torque value calculation section which calculates, when the hoisting manipulation being input, based on a detected load value, a second compensation torque value for enabling the electric motor to generate a load bearing torque which is a torque in the hoisting direction and necessary for bearing a load of the load value.
