:: Industry Wide Problem ::

The loads moved by a typical material handling vehicle come in a variety of different shapes, physical sizes and weights.

The majority of the forklift operators will experience some difficulty with problems relating to the theoretical forklift lifting capacity as indicated on the manufacturer’s ID plate and the unknown load weights that are moved within the material operating facilities.


When the weight of the load is not clearly marked and the loads are moved to various lifting heights, there is a danger of the vehicle stability. The travel speed and turning radius that cannot be easily judged will have a substantial effect on the load center of the vehicle. The forklift operator must deal with unknown elements that will have an effect on changes in the vehicle’s center of gravity that has moved outside of the "Stability Triangle" without the operator’s knowledge. It is well know that this can result in the possibility of the vehicle tipping which may cause damage to the goods and the equipment as well as compromising the operator’s safety.




         

ED2-SLL

 Overload Indicator in % of Vehicle Lifting Capacity

 

 

Lift-O-Graph ECCR-125 Series

Material Handling Vehicle Lift Activity Data Recorder in % of Vehicle Lifting Capacity



The ED2-SLL Series SkidWeigh is an electronic device that can be installed on any forklift truck in order to convert it into a mobile load weight indicator showing in % of vehicle lifting capacity.

Every time a skid is picked up, the hydraulic pressure on the forklift is automatically activated and converted to a load weight measurement and presented to the operator.

The newer ED2-Series is digital load weight indicator showing in % of the vehicle lifting capacity.

 % = Known Calibrated Weight x 100 : Forklift Lifting Capacity
