A swing method for installing a splay saddle 4 at a restricted site comprises the following steps: marking a hoisting point 21 below a frame system 1 and fixing a rack winch 5 to the ground; moving the saddle to a hoisting area on a trailer 3; connecting the saddle to a hoisting winch 13 on the frame system and to the rack winch and operating the hoisting winch to lift the saddle from the trailer; operating the hoisting and rack winches to lift, swing and land the saddle; operating the hoist and rack winches to swing the saddle gradually to the hoisting point; operating the winches to lift the saddle to the height of a splay saddle buttress 7; and, translating the saddle along the frame system and connecting the saddle to the buttress. A buffer device 6 may be provided which slides along a track installed between the rack winch and the hoisting point. The saddle may land on the buffer as it is swung to the hoisting point.
