System designed to handle several
types of loads;
Commonly used for the transport
of x-mas trees;
One tractor can drive several
pallets at same time.
Tractor type
The pallets can be custom made to
perform several functions, ex.
- Fitted with man riding cranes;
- Fitted with working structures;
Several pallets can be push/pulled
at once with one tractor;
Pallets use polymeric bearings to
contact the skidding beam.
Generic pallet
Several lifting points to easily
move tractors and pallets.

Lifting points
Several lifting points to easily
move tractors and pallets.
Optionally clamps can be added on
the pallet to avoid sliding while
they are in parking position.
The pallets are secured in position
when connected to the tractor
without further requirement due to
the fail safe clamp feature;
In case of sudden pressure loss,
the front clamp automatically locks
(Fail safe).
Fail safe clamp
Quick connection system between
pallets and tractor without the
requirement of tools;
The interface component is aimed
to significantly reduce operator
effort for the connection;
Connection parts can also be
made extensible to further ease up
the process.
Pallet interface
The back clamp shoe uses friction
made by 2 heavy duty hydraulic
cylinders to clamp the skid beam;
At all times there is at least two
clamp locked (Forward or back
clamps acc. to movement);
The hydraulic cylinders are fitted
with load holding valves.
Back heavy duty clamp shoe
Shoe geometry is optimized to
reduce stress from the skidding
beam, allowing a overall
lightweight skidding beam;
Is easy to detach the clamps from
the skidding beams using the
rotation pin and removing the
safety locks.
Front shoe CAE model
The tractor includes one dual hose
reel to handle one and one 1 hydraulic hose;
The front clamps are powered
using hoses routed in one
articulated arm from the tractor.
Hoses routing
The stack up guide engages the
TTRD stabilizing it, for stack up;
The articulated arm is hydraulically
actuated, with variable angle
positions to allow greater control;
The stack up dolly is moved using
one hydraulic cylinder in the
vertical axis.
Stack up guide
The TTRD is lifted using a
dedicated crane available in the
stack up area.
Stack up guide
Dual speed system allows to fast
recover between intermediate
positions;
The hydraulic cylinders are driven
according to operator selection on
the control panel.
Dual speed
The control panel is integrated on
the operator platform;
The hydraulic control valves are
located under the control panel,
with easy access but protected
from the elements.
Control Panel
The control panel integrates:
- Forward/Backward control;
- Front/Rear clamping;
- High/low speed;
- Alignment control;
- Pressure gauges to monitor
hydraulic cylinders pressure.
Control Panel
The hydraulic system is made
simple and reliable with the
minimum required parts, functions
can be added or removed
according to client specifications.
Control Panel
Bumpers on the pallets allow to
push them even without linking
them to each other.

The self propelled pallet has
extended capabilities when
compared to a passive pallet.
The pallet has the particularity of
being able to move not only back
and forward, but also sideways.
The pallet is controlled by a
lightweight remote control.
Pallet type
The propelling mechanism uses
slots on the skidding beams to lock
to it and push/pull the pallet;
The pallet is ALWAYS LOCKED to
the skidding beams by means of at
least one locking shoe.
Locking shoe
The stacking in alternative can be
performed on the cargo ramp;
For this type of operation
procedure, the cargo ramp is fitted
with the stack up guide in the main
elevator.
Cargo ramp with stack up guide
The locking shoe block completely
the pallet in place;
The hydraulic locking provides a
safer locking capability compared
with gravity locks, that have always
one unlocked direction;
The shoe has one lateral
inspection window to visually
confirm the locking function.
Locking shoe
To lock the moving direction, it has
one swivel locking mechanism on
pallet corners;
The movement is performed at
intersections and is a warranty that
the user accurately placed the
pallet for direction change.
Direction locker
Bidirectional function
To move in two direction the pallet
has 4 hydraulic cylinders actuated
independently;
Each cylinder has it own self-
sustained locking shoe.
