HYDROGEN POWERED STACKERS

Hydrogen powered BELET stackers



he novelty of the hydrogen drive project applied to the Belet F 12APP3VZ / -FFL
/ H2 stacker is a completely new concept among manually operated stackers
worldwide. For the initial development of this project, a standard stacker with
a load capacity of 1200kg and lifting height of 3000mm with a full free lift
with a mechanical chain system connected to the pull-out frame and fork was
used. The chassis B2014 was fitted with a commonly used 24V / 1300W engine and a
24V / 2200W hydraulic unit. The 24V / 240Ah battery traction battery and the 24V
/ 30Ah integrated charger have been removed from the chassis and a loose space
has been replaced by a hydrogen system block. This system consists of a special
DC / DC fuel cell, a hydrogen generator (invented by a group of scientists from
the Charles University mathematical-physics department led by Prof. RNDr.
Vladimír Matolin DrSc), an electronic module, special HE3DA lithium battery
(invented and patented by a Czech scientist Jan Procházka Ph.D.) and pressure
tanks with liquid hydrogen. This finalized hydrogen drive block will be able to
be installed in a variety of stackers, and in all battery-powered equipment,
including electric cars.



Considering that it is a completely new concept of minimal battery maintenance,
when the battery is being charged while the stacker is operated and the time
required to fill the hydrogen tank is in the order of a few minutes.( like gas
filling at the gas station) the use of these trucks is a great asset and a
revolution for continuous operating without the need to recharge the battery
with a charger.



Standard electric stackers are equipped with traction acid batteries that
require regular maintenance and battery charging to ensure long life and
long-term operation. The disadvantage is the necessity to park the truck when
charging , what takes several hours. Improvement of this situation is provided
by maintenance-free lithium batteries, which have the option of continuous
charging at shorter intervals.
