2. Structural characteristics
SDA manual hydraulic stacker consists of a hydraulic system and a door frame.
The stacker uses a manual hydraulic jack (hydraulic device) as force to lift
heavy goods, which are pushed, pulled and handled manually. The hydraulic device
is equipped with an oil return valve and the fork decline speed is controlled via a
hand lever to make the operation of the hydraulic system correct, safe and reliable.
The door frame is welded with high quality section steel such as to good rigidity and
high strength. Universal wheels with braking device are adopted as the back wheels,
which can rotate freely, easily and flexibly. Both front and back wheels are installed
on wheel shafts with ball bearings so as to rotate flexibly. Wear-resistant and durable
Nylon wheels are adopted so that it is not easy to damage the operation ground.
When lifting goods, insert the forks under the pallet of the goods, when
necessary, brake the back wheels and pull the hand lever. The pinch wheel presses
the pump core to make the oil in the pump cylinder flow into the piston cylinder, in
order to push the piston rod move upward and lift the forks upward via a chain for a
two times travel. Pull the hand lever back and forth so as to lift the goods and
achieve the purpose of lifting. When the forks are lifted to the maximum height, the
pressurized oil flows back into the oil tank via an oil draining hole and in that case,
even the hand lever is pulled, the forks rise no more to avoid damaging components
by impacting the top.
When handling heavy goods, the stacker is able to travel via manual pushing
(pulling).
