Hyvinkaan Tieluiska is the finishing contractor on a major highway project in Finland, designed to improve the Helsinki ring road junction with the highway to Tampere—the country’s second-largest city.
It is critical that the job be completed on time, meaning the contractor needs strong, productive, versatile equipment that can work quickly.
Hyvinkaan Tieluiska used two different excavator models for this time-sensitive project—a Gradall XL 4300 III with a rough-terrain wheeled undercarriage and a Gradall XL 4200 II crawler for challenging work on very rugged terrain.
Both machines were involved with grading the correct profiles on the banks and spreading topsoil before grass seed could be sprayed to provide protection from erosion.
For extra reach, both machines were equipped with 8-ft boom extensions and Engcon tiltrotators with hydraulic in-cab attachment change capability.
The excavator booms can rotate attachments 220 degrees, and take advantage of a low-profile telescoping boom movement that allows them to work in tunnels and under bridges and trees.
The tiltrotator complements the boom movements. The boom-end attachment delivers a 360-degree rotation and a tilt up to 40 degrees, allowing the machine to do even more precise grading work from virtually any angle and on very uneven terrain.
The XL 4300 III model also is equipped with steer and direction change on the joystick with laser guidance override so that the machine automatically follows pre-set steer profiles.
