Rainger Linear 47
OPERATION
Closed Delivery
Cart Path
The cart path must be maintained in a smooth, hard
condition to allow the poly hose to slide freely over
the surface.
Poly Hose
The standard poly hose wall thickness varies de-
pending on which inlet the hose is used on and the
size of hose.
Inlet Size Wall Thickness
Side Inlet 4.75 in SDR 17
6 in SDR 11
Center Inlet 8 in SDR 17
A heavier wall SDR 11 – 6 in poly hose is used with
the side inlet because of the tighter bending radius of
the hose and the stresses of auto reversing.
Moving Poly Hose
Use a 5 ft (1.5 m) nylon sling as shown when moving
poly hose. See Figure 47-1.
Cart Weight
Weight may be added to the cart as required for
increasing the hose pulling capability. The cart tires
may be filled with a weight additive and other weights
added to the cart frame as needed. See Figure 47-2.
Hose Bumpers
The installation of hose bumpers on the cart can re-
duce the hose handling labor, but may require heavier
wall SDR 13.5 or SDR 11 poly hose due to the tighter
bending radius of the hose. See Figure 47-3.
Pump
To boost water pressure after the hose, the Rainger
Linear hose drag cart can be equipped with an en-
gine driven pump.
