摘要： An extendable, load-bearing structure has a main structure and a driving element. The main structure has at least one driving arm. The driving element is placed in connection with the driving arm to drive the extendable, load-bearing structure between first and second positions. The extendable, load-bearing structure has a lock mechanism, and a supporting structure. The supporting structure has at least one supporting arm that is shorter than the driving arm of the main structure. The supporting arm has at least two supporting-arm elements which are connected to each other by joints. The supporting-arm elements of the supporting arm are substantially in line when the extendable, load-bearing structure is in its second position. The lock mechanism is arranged to releasably lock the supporting-arm elements of the supporting arm in position when these are in line.

摘要： An apparatus and method are for cutting and pulling of a casing in a well. The apparatus comprises a housing connected to a wired connection, a cutting tool arranged in connection with the housing, where said cutting tool is rotatable around the longitudinal axis of the housing and arranged to be able to provide at least one cut-out in the wall of the casing and to be able to cut the casing, and a holding device for controlled holding of the housing in the casing. The apparatus is provided with at least one radially displaceable gripping means arranged to go into engagement with the at least one cut-out in the wall of the casing. The method comprises bringing the apparatus down into the well; positioning the apparatus in order to carry out a first cut; carrying out the first cut; positioning the apparatus in order to carry out a second cut; carrying out the second cut; one of the first cut and the second cut comprising cutting of the casing; bringing at least one gripping means into engagement with at least one of the first and the second cut; and pulling the cut casing out of the well by means of the apparatus.
