In the early 2000’s TECNA developed the first AtEx-certified Spring Balancer, in order to offer a solution to customers with specific needs to work in presence of flammable gases or dusts, such as gasoline, alcohol, gas, grains or flour.

It is the most complete line and covers load ranges from 0.2 to 100 kg (0.44 to 220 lbs), and stroke lengths from 1600 to 2700 mm (5.25 to 8.86 ft), plus rope extensions.
