TECNA DESIGN MEANS

LESS MOVING PARTS
STATE OF THE ART KNOW-HOW


Design simplicity and quality manufacturing allow around 50% LESS COMPONENTS compared to competitors.

SIMPLE, TOUGH & RELIABLE

Less moving parts, other than an adequate manufacturing quality means more reliability.

TECNA patents have a design that allow to have about 50% less of components when compared to competitors.

TECNA patent design allows to have only 2 moving parts against 20 parts of the competition.

In 10 years of production hydraulic breaker class 200 kg (for excavator size from 2800 kg to 4500 kg), 4000 units sold: failure components in contact with oil (pistons and/or cylinders) only 4.
