Abstract
A transportable, elevating operator cabin for use in connection with controlling coiled tubing injection equipment comprises a cabin including control elements; an elongated flexible element of fixed length, such as a belt or chain, extending under the cabin, between two, elevated points on adjacent structures located on opposite sides of the cabin; and a take-up mechanism for shortening the length of the flexible element between the two, elevated points. The take-up mechanism is mounted in a fixed position relative to the cabin so that operation of the take-up mechanism results in elevating of the cabin with respect to the adjacent structures. The cabin may be raised to a distance roughly equal to the height of the cabin while maintaining a compact design not much larger than the cabin itself that is suitable for transport, and the arrangement avoids mechanical complexity and costs associated with using other types of lifting mechanisms.
