Operational principal
The
OP-LCM Series SkidWeigh
system operational principal is
based on the hydraulic pressure transducer installed in the vehicle
lifting hydraulic circuit that will automatically activate the proprietary
lifted load “measurement algorithm”. The increase in pressure is
converted in an electronic signal at the sample rate of 16000
readings per measurement cycle during the lifting operation. The
system will automatically calculate and display lifted load in
percentage throughout the entire lift height operation of the vehicle.
The readout is compared to the maximum allowed lifting load of the
vehicle at 24” load centre as per manufacturer specifications shown
on the vehicle name plate. The master OP-LCM readout is updated
every second and will be clearly visible to the operator on the slave
indicator mounted on the lifting platform .
Pressure transducer installation
The pressure transducer must be installed in the lifting hydraulic line
between the lift control valve and lift
cylinder(s).
In majority of cases
a T-piece is used to install the pressure transducer in lifting hydraulic line. In some
cases you can install the pressure transducer in the flow divider, drilling and tapping for 1/4”-18 NPT male in spare
plug (if only single or double mast configuration) or in the body of the flow divider. Also, you can drill and tap on any
“larger elbow” that might be available in the hydraulic lifting circuit in the vehicle.
Pressure transducer installation precautions
Before mounting the pressure transducer in the hydraulic lift circuit make sure
that system is pressure free.
There are two ways to do that:
1. Place the forks on the ground in their lowest position and make the hydraulic
system pressure free by tilting the mast forward. The chain(s) should be slack.
2. Lift the forks and position them on the top of a supporting fixture. Start
lowering the lifting cylinder into its lowest position. Be sure that chains are slack.
Make sure that that installed pressure transducer will not touch any moving
parts or assembly of the vehicle while in normal operation.
