    摘要： A hoisting device (10) comprising a hoisting cable (1), a winch, a crown block (5) and a traveling bottom block provided with a load attachment device (55), wherein both the crown block and the traveling bottom block comprise one or more sheaves having an essentially horizontally extending rotation shaft (26) about which sheaves (31a, 31b, 33d, 33b, 33c, 33d) the hoisting cable (1) is reeved. At least some of the traveling bottom block sheaves are associated with a releasable connector, and are thereby detachable from the load attachment device and displaceable to an inoperative position. The invention is characterized in that the rotation shaft of multiple traveling bottom block sheaves and multiple crown block sheaves is essentially perpendicular to the rotation shaft of remaining multiple traveling bottom block sheaves and remaining multiple crown block sheaves.

    摘要： A hoisting crane (20), comprising: - a substantially hollow vertical column (21) with a top (23), - an annular bearing structure (25), which and carries a jib connection member (26), - a jib (24) - a column top cable guide (40; 140) - a topping winch (30) and an associated topping cable (31) for pivoting the jib (24) up and down, -hoisting cable (36) for hoisting a load,- wherein hoisting cable and the topping cable extend from the associated winch upward through the column to the column top cable guide to the jib,which is mounted via a bearing structure at the top of the column, rotary movements of the jib about the vertical column. In an embodiment a mobile subframe (86; 150) is mounted on column top cable guide (40; 140), and supports an intermediate topping cable pulley assembly (88; 153), such that - in a topped up position of the jib - an angle alpha between the jib and the topping cable is greater than the angle between jib and an imaginary line to the topping cable pulley assembly on the column top cable guide.In another embodiment a mobile subframe (80,85) is provided externally to the column, mounted on the jib connection member (26).In further embodiments the column has a separate upper part (211,212) which can be lowered, or a pivot assembly (215) at the foot of the column which allows the column to be fitted to a transport position.
