Rice Lake TradeRoute HL Series - Installation and Service Manual (Legal-for-Trade) - Manual (Page 7)

Introduction 3
1.2 Overview
Trade Route
is a patented, Legal for Trade, NTEP and Measurement Canada approved, mobile weighing device.
Trade Route
has a height profile of only 2-3/8 " . This allows a truck’s center of gravity to remain practically
unchanged. The entire package is designed so that it is almost unnoticeable to avoid detracting from the appearance
of the unit. The scale modules come preassembled for ease of installation.
Features and benefits of the
Trade Route
system include:
• Quick transition between weigh and transport position (about three seconds).
• Off level operation.
Trade Route
can be used in very hilly terrain since it can operate up to six degrees out of
level in any direction.
• The measurement received from the scale is shown directly in lb or kg; so conversion from gallons or liters
is not necessary.
• The entire system is temperature compensated so it can be used at any time of the year in all weather
conditions.
1.3 Important Installation Notes
When installing the
Trade Route
system:
• Do not weld to any part of the scale system. Electrical currents required for welding can damage the load
cells.
• Clearance of at least 2 " must be allowed between anything that is a part of the scale (lift plates, container)
and anything that is not part of the scale (truck frame, bumper, axles, wheels, truck cab).
1.4 Vehicle and Container Selection
Vehicle selection is an important part of the installation process. When mounting the
Trade Route
on a truck frame,
be sure to select a truck that will carry the load and be properly balanced.
Important
Scales must be installed on a rigid base for accurate weighing. Installer must avoid a chassis that has the
possiblilty of excessive flexing or not be able to remain rigid during lifting and weighing proccess.
The container used to transport product must also be suitable for use with the
Trade Route
system. The container
(tanks and body) must be capable of supporting its own weight plus the total weight of product at two locations
along its length.
Important If this is not practical, a frame must be built to support the container in the weigh position.
1.4.1 Vehicle Requirements
1. Truck frame width (outside to outside) must be between 33½ " and 35 " .
2. Truck frame behind the cab must be as long as the container plus 6 " to 12 " .
3. There must be enough axle capacity for the container, product, and scale components.
4. Truck must have a bumper attached to the truck frame.
5. Fenders must be attached to the truck frame, not to the container body.
6. If truck is equipped with lift gates, they cannot attach both to the body and chassis.
1.4.2 Hydraulic Requirements
WARNING
When working with hydraulic hoses and fittings, avoid a hazardous release of fluids by relieving pressure
before disconnecting. Securely tighten all connections before applying pressure.
Truck requires a hydraulic pump with the following specifications:
1. Maximum pressure capability of 3000 psi (pressure is usually set to approximately 1800 to 2000 psi).
2. Minimum flow of 5 GPM (lower flow is acceptable, but will increase the time to raise and lower the scale
into and out of weighing mode).
3. If used with other hydraulic control valves, pump must match the control valve (i.e., open center pump
with open center valve and constant volume).
