Cover drives for hydraulic drive, ASH

Type
Part no.
The auxiliary equipment for the hydraulic drive ASH of the pushrod
discharge for activating hydraulically opening bunker covers. The cov-
ers are opened by the hydraulic cylinder when the key switch button
is pressed. When the key switch button is released, the load holding
valve fixes the cover in position.
Standard delivery:
■ 1 valve block per cover, each equipped with:
– 2 solenoid valves
– 1 load holding valve
– 2 non-return throttle valves

Silo filling screw conveyor FS 300

Part no. 7387 808
Supply screw conveyor in open version for filling a fuel store located
inside a building from an external tipping trough. Generally, at least
two silo filling screw conveyors are required. The silo filling screw con-
veyors are routed through the fuel store in such a way so as to maxi-
mise filling.
Standard delivery:
■ Silo filling screw conveyor according to order data
■ Mounting brackets for wall mounting
■ Duct for routing through a wall

Drive, silo filling screw conveyor

Part no. 7387 898
The drive is located inside the building but outside the fuel store. This
means that the silo filling screw conveyor has a pulling effect. For
6
safety reasons, the key switch button must be located close to the
tipping trough. The operator must permanently monitor the filling proc-
ess from outside. Releasing the button stops the screw conveyor
immediately.
Standard delivery:
■ Drive unit, silo filling screw conveyor
■ Spur geared motor with matched torque and pump rate, 3 x 400 V
■ Control of screw drive according to boiler control unit
■ Key switch button ON/OFF for installation of a locking cylinder on
the customer side (installation close to cover).

activation (AF, AG, AP, external discharge)
Control:
According to the boiler control unit
One key switch button OPEN/OFF/CLOSED per cover for installation
of a locking cylinder on the customer side
(installation close to bunker cover so that the motion process can be
monitored).
Note
Screw conveyor length with drive unit max. 10 m
