<p>In the transport position, the slide (10) is positively locked to the mast (4) which is mounted directly on the truck chassis (1). This can be effected by a locking pin (17) sliding in a bearing (16) in the mast and engaging in a recess in the slide. A ball-type grip is at the free end of the pin, which has a ring fixed permanently near its end of the pin, which has a ring fixed permanently near its end engaging with the slide. A spring acts between the bearing and the ring, thrusting the pin into engagement with the slide.</p> |
