PRODUCT OVERVIEW
The
PEBCO®
Dustless Loading Spout (DLS) is a device of two or more conical sections that bridges the gap
between a load-out controls device such as a cutoff gate, conveyor, etc. and a hopper, truck, railcar or barge. The
DLS is retracted to allow the moveable transport device to be positioned and then it is lowered to facilitate dust-
free loading of the bulk solid product. Product is dropped into the inlet cone and travels down the cone assembly,
out of the outlet cone, and into the container being loaded. As product moves down the spout, dust is contained in
the dust sleeve encasing the cone assembly, and routed to a dust collection system through an outlet in the tub.
2.1 STANDARD COMPONENTS
The following components can be found on all
PEBCO®
DLS units:
DRIVE MOTOR AND GEAR REDUCER
The motor and gear reducer are mounted to the outside of the housing assembly to provide easy
access. The motor is powered by a three phase power source and is engaged by a command from
the operator. Motor and gear reducer combinations vary depending on the application; see the
manufacturer’s component data in the associated cut sheet for detailed manufacturer data.
DRIVE SHAFT AND LIFT CABLES
The drive shaft is supported by flange bearings mounted on either side of the housing assembly and
raises and lowers the spout by way of three lifting cables which run from cable drums on the shaft to
the outlet assembly. For lifting cable inspection and replacement, refer to
Section 6.9.1
ROTARY LIMIT SWITCH
The rotary limit switch is connected to the shaft by a chain drive. The rotary limit switch dictates the
limits of travel for the DLS by dropping out the motor contactor to stop the motor
when the adjustable
cams within the switch reach positions which correspond to the upper and lower limits of travel.
These limits can be changed as desired by adjusting the switch; for more information on rotary limit
switch adjustment, see
Section 6.7
. Refer to the associated cut sheet for manufacturer data.
INLET CONE
The inlet cone is contained within the housing, and connects the spout to the equipment above by
way of a sealed flange. Material enters through the inlet cone and is passed down either to the
outlet assembly or an intermediate cone assembly.
CONE SUPPORT CABLES
The cone support cables ensure that each cone is suspended level and at the correct height. The
cable runs from the housing assembly to the outlet assembly with intermediate cones connected
to the cable via U-bolt cable clamps. For cone suspension cable inspection and replacement, see
Section 6.9.2
