Boom section
Boom section

The boom section is composed externally by a single metal sheet and internally by two “C” section bars. This industrially adopted solution provides the boom with high strength combined with remarkable lightness.

 Subframes
Subframes
The Sigma 4 subframes are formed by connecting the tractor at three points, guaranteeing unsurpassed robustness and solidity. Their fish-belly beam provides a uniform load distribution at every point. Each tractor model has its own specific subframe that adapts perfectly to its contour.

The TC Basic joystick is supplied as standard with all mechanical distributors and controls the hydraulic lines for loader lifting and implement movement. Its shape has been carefully developed by Sigma 4 to offer maximum comfort under all conditions of use, no matter where in the driving area it is installed.

 Support feet
Support feet

The support feet, equipped with fine adjustment system for the CHROME, IRON and TITANIUM models, can be singularly adapted to ensure maximum safety and adaptability during parking manoeuvres on all types of grounds, even the most uneven. During normal operations, the feet are locked inside the loader boom, so that they do not interfere with the front tractor wheels.
