For installation of the complete set of loading equipment openings on a front beam,
side members and the tractor clutch coupling case are used. For the purpose of unloading
a semi-frame and a tractor clutch coupling case, it is required to use adjustable bars or
other constructive elements connected to rear semi-axles tubes of the rear axle which
transfer a part of push force to the tractor rear axle. For rigidity maintenance it is desirable
that the right and left parts of the loader mounting frame are rigidly connected with each
other.
Loader installation scheme is shown in figure 4.13.1.
1 – loading equipment kit for the tractor; 2 – crossed linkage of loader frame; 3 –
tapped rod; 4 – loader bucket; 5 – rear ballast weight.
To provide sufficient drawbar power generated by tractor rear wheels, it is neces-
sary to create sufficient load on the rear axle which shall make not less than 60 % of trac-
tor operational weight considering the installed loader weight.
The right proportion of loads on tractor axles can be achieved by rear axle ballasting
with loads, solution filled in wheel tires, rear counterweight (hook-on bucket with ballast
load) attached to rear lift linkage.
ATTENTION: IN THE LOADER OPERATION MANUAL DESIGNED FOR CON-
SUMERS, LOADER MOUNTING ORDER SHALL BE SPECIFIED WITH PICTURES IN-
CLUDING INFORMATION ON SHIFTING AND DISMOUNTING OF TRACTOR ELE-
MENTS.
In the loader design, safety and locking devices (fast coupling clutches, slowing-
down valves, overload limiters and others) shall be provided excluding conflicting motion of
gears, overloads and breakages in operation when there is excess of permissible pressure
values in the hydraulic system, rated load capacity or drawbar power.
In the mode of ground cutting, it is necessary to provide protection of tractor and
loader chassis from overload. Loader operating part overturning (bucket and etc.) can
happen due to actuation of a special valve integrated in the loader system.
In order to avoid breakages in loader design for the purpose of loader lowering
speed limitation, the loader shall be equipped with slowing-down valves in the lifting cavity
of loader hydraulic cylinders.
Loader design shall provide a possibility of fixing operating parts in transport posi-
tion.
