ABSTRACT:
The invention relates to a bottom hook block system for a given maximum load, for providing differently portative bottom hook blocks for a crane, especially for a heavy lift crane. The bottom hook block system comprises four individual roller blocks (1a–d) with a plurality of pulley blocks, two load hooks (2a, b) and two intermediate links (3a, b) by means of which two individual roller blocks (1a, bor1c, d) can be combined to a double roller block (4). An equalizing link unit (5) consists of two equalizing links (6, 7) that are interlinked via a joint support (8) with a vertical and at least one horizontal rotational axis. One of the equalizing links (6) is linked via a first horizontal hinge (10a, b) with the two intermediate links (3a, b). The other equalizing link (7) is linked via at least one bearing block (11a, b) with a second horizontal hinge (12a, b) with the two load hooks (2a, b). The load hooks (2a, b) can be swiveled about a vertical rotational axis in the respective bearing block (11a, b). A bearing connection (13) is provided in at least one of the intermediate links (3a, b), the connecting dimensions corresponding to the second horizontal hinge (12a, b).
