The new Gradall Model XL 4300-II is a hydraulic excavator in the 45,000-pound class offering the combined advantages of a tilting, telescoping boom for full versatility — even on low-overhead jobs — plus wheeled mobility both on and off paved surfaces. The boom enables work in places where a conventional knuckle boom cannot — under bridges, beneath tree limbs or in tunnels. Maximum digging depth is 20 feet, 11 inches, while boom radius at groundline is 30 feet. The rated boom force is 22,075 pounds and bucket breakout force is 25,449 pounds.

Dressta introduces improvements to its line of wheel loaders including modern styling and a restyled tilt-open engine enclosure for improved engine access. Included on all three models — 510E, 515E and 520E — is a single lever equipment control joystick designed to give the operator fingertip control of the bucket and boom. The lever uses the oil pressure to activate the main valve spools to make bucket and boom movement smooth and easy. Other featured improvements include electric-controlled transmission, hydrostatic steering and an optional ride control system.
