A hoisting system includes a hoisting cylinder assembly which is arranged vertically. The hoisting cylinder assembly includes at least one hoisting cylinder, a lower part, and an upper part, the upper part being moveable in relation to the lower part. At least one sheave is arranged in the upper part of the hoisting cylinder assembly. A winch which includes a base is fixed in relation to the lower part. A first wire is operatively connected to the winch and extends from the winch via the at least one sheave to a yoke so as to suspend the yoke from the at least one sheave.

Hoisting system

A hoisting system includes a hoisting tower, a yoke which is movable relative to the hoisting tower and which carries a tool, a first winch, a second winch, a first sheave arranged in a top section of the hoisting tower, a second sheave arranged in the top section of the hoisting tower, a first hoisting member arranged to extend from the first winch to the yoke via the first sheave, a second hoisting member arranged to extend from the second winch to the yoke via the second sheave, and at least one first releasable connector which selectively connects the second hoisting member to the yoke.
