hydraulic boom vang
ARTE - BAMAR
Bamar hydraulic boom vang is safe and easy to use. Vang cylinders are equipped with a pressure rod release. Such pressure is charged through a pneumatic valve placed on the cylinder body near to the boom-side vang terminal. Pressure depends both on the release speed you wish, and on the thrust needed to contrast the weight of the boom.
Pressure has to be charged indicatively at 713-785 psi (50-55 bar). All VANG cylinders may be used with double effect function(push-pull).
