Lifting boom is made of several different high density steel. We have used Ruukki Sternx (better known as Weldox 700), Optim 650 and Hardox 400.
The whole boom structure has designed carefully to avoid unnecessary weight, but to offer maximum strength within given target values.
One of the used target values was boom lifting power: 3000kg at distance of 3m from the tilt joint.
Telescope boom length is 1540mm when shortest and 3140mm when longest. Telescope includes base boom and two extensions.
Winch pulley structure on the top of the boom is measured to last more than 14ton pulling forces on sideways.
T-boom in the end of telescope is equipped with automatic wheel lift.
