The ED2-SM Series SkidWeigh
System is an electronic device that can be installed on any forklift
truck in order to convert it into a mobile check weighing scale
with overload warning.
Every time a skid is picked up, the hydraulic pressure on the
forklift is automatically activated and converted to a weight
measurement and presented to the operator visually via a LED digital
indicator.

Load and Vehicle Stability
One of the most important elements to know about a forklift is the
rated load capacity. It is defined as the maximum weight of
material that can be handled on the forks at a specific load center.
When the weight of the load is not clearly
marked, the standard practice is to lift the load off the ground and
get a "feel" if the vehicle is stable. This becomes
a problem when unknown skid weights are picked up from the storage
racks at various forks heights and mast angles.
Solution
The SM-Series SkidWeigh with it’s
bright LED load weight readout will "flash" when overload
is present. Optional buzzer will be activated as well when vehicle
overloaded.
Installation
The SM-Series SkidWeigh can be installed
and calibrated by a local forklift dealer or the end user’s forklift
mechanic.
