Abstract

A load handling tool which is to be attached to a crane boom and comprises first and second bucket jaws (10, 30) pivotally connected to a carrier head (2) via a respective pivot arm (11, 31), and an actuating device (4) for pivoting the pivot arms and the bucket jaws in relation to the carrier head. Each bucket jaw (10, 30) is articulately connected to the associated pivot arm (11, 31) and pivotable in relation to the pivot arm between a fold-down working position and a fold-up storing position, wherein the bucket jaws are configured to be located between the pivot arms and to rest against each other in the fold-up storing position. Each bucket jaw can be locked to the associated pivot arm in the fold-down working position by a locking device (14, 34). The invention also relates to a hydraulic crane provided with such a load handling tool.

Description

technical field [0001] The present invention relates to load handling tools. The invention also relates to a hydraulic crane comprising such a load handling implement. Background technique [0002] Ordinary truck-mounted cranes may be provided with load handling means mounted to the outer end of the crane boom in the form of a so-called outer boom that is telescopically extendable and articulated to a so-called inner boom. Another crane boom, wherein the inner boom is in turn hingedly connected to the rotatable column of the crane. [0003] A load handling tool is previously known from EP 2 778 109 A1. This previously known load handling tool has the form of a clamshell bucket with an open casing and is intended to be mounted to a crane boom, wherein one of the jaws of the clamshell bucket (bucket) A recess is provided for receiving a portion of the crane boom to allow the crane boom and clamshell bucket to assume a compact parking position. The clamshell bucket disclose...
