SENNEBOGEN 8130 EQ: Innovative balance technology
and electric drive at Pollmeier in wood logistics
implementation
At the beginning of 2014, with the new SENNEBOGEN 8130 EQ, an exemplary
machine concept went into operation at Pollmeier Holzwerke in Creuzburg, in
the German state of Thuringia. The materials handling machine for charging
the logwood cross-cut system and the conditioning basins is stationed above
the plant. The new development of the Lower Bavarian machine engineering
specialist is consistently balanced, and thanks to the classic lever principle
and electric drive, it guarantees the lowest energy costs and operating costs in
daily operation.
Pollmeier Massivholz GmbH is pursuing an ambitious project. In the future, the
world's first veneer layer lumberyard should be capable of producing glued laminated
beech panels on a large scale. The plant is still in the erection phase, even though
some sections, such as the logwood cross-cut system and the conditioning basins
are already in operation. A SENNEBOGEN 8130 EQ, which unloads the logs from
the arriving trucks and charges the plant, stands at the beginning of the overall
process. The stationary machine, which was delivered by dealer Louis Scheuch at
the end of 2013, conveniently covers an area of 2300 m², and thus can safely service
the conditioning basins that are arranged in a fan shape. In the first step, the
machine removes the beech trunks from the delivering trucks, and positions the
trunks on the centrally positioned logwood cross-cut system. After fully automated
peeling and debarking, the trunks go into the conditioning basins, which are arranged
in a fan shape, for 48 hours. In the future, 20 of these basins will bring the trunks to a
core temperature of of 72° Celsius to prepare them for the subsequent veneer
cutting.

Thanks to the central position of the machine, all work steps can be optimally worked
through in terms of logistics. The machine is powered by an 160 kW electric motor.
All the equipment is moved by just two cylinders. The functional principle is as simple
as it is effective: A coupling bar that is routed parallel to the boom, connects the stick
with the rear counterweight and ensures an effective transmission of force. With each
work movement the forces are held in balance in accordance with the classic lever
principle. Thus the expenditure of force for moving the equipment can almost be
completely dispensed with. Like the entire plant, the SENNEBOGEN 8130 EQ is also
electrically powered. As opposed to conventional hydraulic material handling devices,
the balancing technology of the 8130 EQ enables savings of energy costs and
operating costs of up to 75%, as compared with diesel propulsion.
With a safe working load of up to 5 t at a range of 27 m, the stationary machine not
only covers the entire work area safely, it can even move the heavy covers of the
conditioning basins without external help. Operator Heiko Fuhs has an overview of
the entire plant and controls the entire plant from his elevated position. For the
operator, the proven SENNEBOGEN maXcab Industry Comfort cab, in addition to the
spacious interior, enables an optimal all-around view and an unobstructed view into
the steam basins, thanks to the contiguous inclined armored glass windshield and
floor window. In addition surroundings cameras that keep every angle of the work
area in view are mounted on the equipment.
Up to 40 solid cubic meters of beech wood per hour should be peeled as veneer in
full operation and later pressed to form glued-laminated panels. To do this Pollmeier
procures beech trunks from a radius of 200 km. Just under 130 trucks a day should
be the maximum number at the busiest times, explains production manager, Rainer
Moog, on site. After all one conditioning basin can hold 200 solid cubic meters. With
the SENNEBOGEN 8130 EQ the company has found a machine that combines
energy-efficiency and environmental responsibility with high-performance. Since the

entire plant is a world innovation, the company also relied on state-of-the-art
technology for the charging machine.
In daily operation easy maintenance and safety, in particular, are what counts. The
power pack, which can be walked, on provides optimal accessibility to the motor and
control technology under any weather conditions – easy servicing in its best
implementation. All drive components and control components are brought together
centrally in a spacious machine room. Perimeter railing and the generous step grid
on the mast ensure safety in daily use. The local Sales Partner, Louis Scheuch
GmbH, who also provided support in the concept and erection of the machine, takes
care of on-site service.
Statements:
"The SENNEBOGEN 8130 EQ is the heart of our logistics concept for charging the
logwood cross-cut system and the associated conditioning basins. Thanks to the
central position, the entire plant can be conveniently monitored and controlled from
the operator cab. The combination of electric drive and balancing technology
convinced us right from the start – that's energy efficiency par excellence."

"From my SENNEBOGEN 8130 EQ I have the overview of the entire plant. The
machine can be controlled with precision and sensitivity, and thanks to the wellorganized Maxcab Industry cab and numerous surroundings cameras, I always have
the conditioning basins and the cross-cut system safely in view."
