The hoisting arrangement of a hoist of a of a crane, includes a trolley arranged to move along a main support structure of the crane, whereby the trolley includes a support frame structure; bearing wheels which are fastened to the support frame structure and by means of which the trolley is arranged to move along said main support structure; a hoisting mechanism that has a rope drum for a hoisting rope, a rope pulley arrangement which has upper sheave arrangements and lower rope pulley arrangements and through which the hoisting rope may be guided from the rope drum to an attachment point, and a hoisting member in cooperation with the hoisting rope for hoisting a load; whereby the rope drum is supported to the support frame structure of the trolley so that the axle of the rope drum is parallel to the main support structure. In the hoisting arrangement, the disengagement point of the hoisting rope from the rope drum, the attachment point of the sheave, and the attachment point of the first end of hoisting rope are arranged on the same vertical plane of the hoisting arrangement. The rope drum has a first end towards which the hoisting rope is wound in the hoisting member's upper position, and a second end towards which the hoisting rope is unwound in the hoisting member's lower position. The first rope pulley of the rope pulley arrangement is so placed that the release point of the hoisting rope from the first rope pulley to the first sheave is, in the axle direction of the rope drum, further from the second end than the first end of the rope drum.

A mounting assembly for a cross-rail of an overhead rail system includes a mounting rail, an attachment bracket, and a spring-loaded pin. The mounting rail is configured to mount to a sidewall and includes a bracket receiving recess. The attachment bracket includes an attachment portion and an extension portion, wherein the attachment portion is shaped to correspond to the bracket receiving recess such that the attachment portion is positionable within the bracket receiving recess. The spring-loaded pin is coupled to the attachment bracket and includes a retracted position and an extended position, wherein the spring-loaded pin is biased to the extended position to lock the cross-rail to the extension portion of the attachment bracket.

A support for a trolley, having a running surface that is formed on the support for the trolley, an upper chord, a lower chord and braces that connect said chords together, wherein the braces are designed to be flat, and each brace has a main surface that faces away from the support longitudinally between the upper chord and the lower chord. Two of the braces form a brace pair in each case and are arranged next to one another as viewed in the direction of the longitudinal axis of the support, preferably on the outside of opposite longitudinal sides of the support. To provide such a support, the flat braces are releasably secured to the upper chord and/or to the lower chord. The invention also relates to an overhead transport device having such a support and a trolley that can be moved along the support on the running surface.

A crane system is for a cantilever belonging to a jack-up rig. The crane system has a crane with a suspension member, the suspension member being arranged over the crane. A skid beam is attached to a lower portion of the cantilever, the skid beam being displaceably connected to a plurality of slides arranged on the jack-up rig, the crane hanging on the skid beam. A method is for using the crane system.

A switch assembly for a lift unit includes a switch, an emergency stop device, and a reset actuator. The switch is arranged to move between a closed position, wherein the switch electrically couples a lift motor of the lift unit to an energy source, and an open position, wherein the switch electrically decouples the lift motor from the energy source. The emergency stop device is coupled to the switch and arranged to move the switch from the closed position to the open position. The reset actuator is coupled to the switch and arranged to move the switch from the open position to the closed position, wherein the reset actuator is controllable to move the switch from the open position to the closed position.
