Chapter 3: Installation
3-1 Uncrating the Equipment
Rate monitors are shipped mounted on a skid, enclosed in a plastic wrapper, and contained in
a crate.
1. Remove crate from around the rate monitor.
2. Secure strap of proper lifting capacity.
Caution! Use approved safety straps or chains to lift the rate monitor.
3. Lift the rate monitor until strap is taut.
4. Remove bolts attaching bottom of the rate monitor to shipping skid.
3-2 Mechanical Installation
It is the intent of this section to familiarize the reader with the proper site requirements and
installation procedures of the GH-M rate monitoring system. The information in this section
is NOT meant to replace or supersede an established local or company implemented
procedures. It is meant to enhance them.
The installation procedure should be used as a general guideline for the proper installation
steps required to install a rate monitoring system.
1. Lift the rate monitor and position over machine throat.
2. Set in position and secure by tightening four bolts.
3. Remove lifting strap.
4. Mount the material conveying system receivers on the top of the rate monitor’s surge
hopper. If a mezzanine mounted GH Hopper is being used to supply material to the
rate monitor, attach the flex hose to the top of the surge hopper.
5. Install the weigh hopper onto the load cell bracket. Tighten the two supplied thumb
screws to the flange on the weigh hopper.
6. Check to see that the weigh hopper is completely unrestricted. The load cell bracket
should not touch any part of the plastic housing on the load cell. The tube stub on the
bottom of the weigh hopper should not touch any part of the cast spool. If either of
these conditions are not met, inaccurate weight readings may result.
Site Requirements
This section describes site requirements in detail. These requirements are broken down into
mechanical mounting, electrical connections and pneumatic connections.
Mounting Configurations
The rate monitoring system must be machine mounted.
Note: Use extreme care when tightening bolts on top of the load cells so you do
not spring the load cells. The load cells are extremely delicate and should
be treated with care!
