are supposed to allow you to familiarize yourself with the calculable capabilities of
we can see that when the driver drives onto a high obstacle (the folding
blades do not tilt back) with the velocity of 20 km/h with th deceleration distance
s
= 10 cm the force
acting on the plow and tractor is
–
62 Tons
!!! This amount of force certainly will lead to damage of the
plow and the TPH suspension of the tractor. The table and the pictures could help the operator in
choosing the tractor speed
V
to specific terrain conditions. The table shown above is a demonstration
to show the operator how suddenly the loads change depending on the speed and stopping distance
.
ATTENTION!
Please consider the forces created when we are dealing with a tractor, loader,
whose weight is 6 - 10 Tons
.
ATTENTION!
The operating speed of the tractor-plow unit must always be appropriate to
current working conditions
.
Regulaction of overloding protection
Depending on plow’s operations the gap between blade’s inclination mechanism and its housing
should be regulated
Ø mm
) and so it follows:
❑
if the operations is connected to snow clearing from Road and squares with higher speed e.g.:
V
=
10 km/h and more – the gap on all roller mechanisms should be
Ø
=12 mm. In that case when
coming cross small obstacle lower part of the blade will incline under the force F
=
400
kG,
❑
if the operations is on tough snow (frozen etc.), the above mentioned regulation will make the
blade
incline backwards too often. In that case the gap may be regulated
Ø
to 10 mm – then the force
will increase to F = 550 kG. Higher force of inclination will have negative consequence on rubber
blade’s durability,
❑
if nevertheless operation’s quality is not satisfying eg. work with HARDOX bar and the tough surface
is to be removed or snow the gap can be regulated
Ø
= 0 mm. In that case the
maximum force on
one part of the blade can be not more than F
max
= 1200 kG. With such work an operator should be
. Besides he should control the force on the lower part of the blade
.
