Abstract

See full text

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 to—in a non-operative position—allow introduction of the shank of the tool from below into the shank receiving passage and—in an operative position—engage 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.
