摘要

It includes a horizontal shaft or bar 1 which is connected to a head 2 for coupling at the front lower corners of the container 3, by means of conventional bolts 4. This shaft is anchored by a traction chain or cable 8, being entrained by the action of telescopic hydraulic cylinders 9 located along the tipping chassis or in the actual trailer cradle. The traction chain or cable passes through various return pulleys and is anchored via its ends to respective fixed points on the chassis. The shaft or bar 1 has its fixed ends, a movable central part and a pair of intermediate rollers 13 for support on the rolling tracks 21 of the cradle or tilting chassis 10. There are also small wheels 18 which are located on the other side of the rolling tracks. The container 3 subsequently rests on a roller table 25 and, optionally, on a pair of rows of lateral rollers, all of which rows can be displaced vertically through the action of hydraulic cylinders.
