Forklift Capacity Derating

During the initial scale installation, remind the customer that they must have an updated ID plate on the forklift stating the new lifting capacity and center of gravity information. This is required per OSHA rules and regulations.

CLS Next Gen Pro 3436 model
Vertical center of gravity (VCG) of scale = 10.03 in
Horizontal center of gravity (HCG) of scale = 2.18 in
Effective thickness (ET) of scale = 4.55 in
Weight of scale = 402 lb
Max capacity at 24-inch load center = 5,000 lb
