TRACTOR - TRAILER / SEMI-TRAILER COUPLINGS
There should be nobody present in the danger
zone between the tractor and trailer when it is
necessary to couple / decouple the trailer from the
tractor!
NOTE: Before starting the coupling operation, ensure
that the trailer/semi-trailer is on flat ground, and that the
hand brake / parking brake are properly on. If it has
chocks, always ensure that the trailer’s wheels are
chocked prior to starting the following procedures.
7.1.
TRACTOR WITH HOLE COUPLER
1º Align and move the tractor’s coupler towards the
trailer’s drawbar;
2º Connect the drawbar’s traction/safety chains to
the tractor;
3º Connect the trailer’s hydraulic system pipes to
the tractor’s respective hydraulic sockets (the
tractor must be off);
See Connection of the Tipping Hydraulic System pg. 12
4º Connect the plug of the trailer’s electrical
system to the tractor’s socket;
5º SEMI-TRAILERS
(HMB)
-
Operate
the
drawbar’s hydraulic cylinder to level the
coupling eye with the tractor’s coupler;
TRAILERS (HGMB) - Manually adjust the height of the drawbar with the help of the spring, fixing it
with the chain links; such that this is fixed at an adequate height for the coupling eye to receive the
tractor’s coupling;
6º Slowly reverse the tractor until the tractor’s coupler hole is aligned with the hole of the trailer / semi-
trailer’s coupling eye. When these are properly aligned, put the tractor’s brake on and place the
fixing bolt in the coupler, together with the bolt’s specific safety system;
7º SEMI-TRAILERS (HMB) - Retract the drawbar’s hydraulic cylinder to its operating position;
8º Remove the chocks from the wheels (if fitted) and release the hand/parking brake.
