A conveyor apparatus (2), so-called injector head, to enable feeding of e.g. continuous tubing (7) or coiled tubing through the conveyor apparatus (2) to or from a wellhead and a well below and related to use of well tools. There is provided an apparatus frame (21) within an apparatus cage (5), and a pair of oppositely located, cooperatively movable, segmented continuous belts (28; 29) installed in the frame, each belt (28; 29) comprising a plurality of interconnected) gripper shoe carriers (30) carried and movable by means of a pair of continuous belt drive chains (31; 32), and a gripper shoe (38; 52) cooperative with each carrier (30) to positively engage the tubing. The frame (21) at its lower end (21') is tiltably connected to the cage (5) so as to cause said cage (5) and frame (21) to be mutually tiltable in a tilting plane about a single tilting axis (58) which passes through a stuffing box (22') located at a lower region of the cage (5).The frame (21) has at a top region thereof a pair of rollers (24') between which the tubing (7) passes, a force imposed on one or the other of the rollers (24') causing tilting of the frame (21) relative to the cage (5). |
