2.27.7 Hydraulic hook or lowered link grippers control.
Against order tractor with draft control unit can be equipped with a drawn hydraulic
hook (hydraulic pick-up hitch). Hydraulic hook is intended for operation with semi trailers
and agricultural machines on their basis.
1 – hydraulic hook gripping handle control; 2 – control link; 3 – grippers; 4 – hook
with axle; 5 – uplifting links.
Figure 2.27.7 – The scheme of hydraulic hook control.
Agricultural machines coupling with the hydraulic hook is exercised in the following way:
- using handle 1 (figure 2.27.7) installed in the cab, turn grippers 3 through control link 2
loosing hook 4 axle;
- setting RLL into the lower position by draft control unit operation handle, set hook 4 be-
low the coupled machine loop level;
- slowly move to the position where hook mouth 4 is under the loop and fix hook 4 axle in
gripper tools 3, uplifting RLL into the upper position.
For discoupling of the agricultural machine from hydraulic hook do the following:
- turn handle 1 into the upper position;
- lower RLL and move forward on tractor;
- uplift RLL into the upper position, fix hook 4 axle in gripper tools 3.
Against order tractor with draft control unit can be equipped with lowered link in-
tended for coupling with semitrailers and trailing agricultural machines.
Coupling and decoupling of agricultural implements to lowered link is exercised in
the same way as to the hydraulic hook.
