Terex subsidiary Genie recently expanded its telescopic boom family with two new models—the S-60 and S-65 Trax models. The new Trax models feature a four-point track system that enhances traction to facilitate travel over difficult terrain.
Designed to operate on a narrower, 8.5-ft (2.6-m) profile, Genie’s fixed-track booms can be transported throughout the U.S. without requiring special oversize load permits and limitations on evening and weekend transport. Because they steer like a wheeled unit, the Trax models can be driven on and off the delivery trailer, and their 14-ft (4.3-m) inside and 21-ft (6.4-m) outside turning radii make it possible to maneuver in close proximity to walls and foundations. The Trax booms have a travel speed of 2.3 mph (3.7 km/h).
“Track booms are ideal for working year-round by enhancing traction for travel in muddy, soft-soil, sandy, snowy, and wet ground conditions,” said Phil Harvey, Product Manager, Genie Industries. “And they can also easily travel over harder surfaces like gravel, rock, concrete and asphalt, and sensitive turf.
Trax models are manufactured with a four-point track system permanently attached to the machine. Tracks, which are made of durable, steel-reinforced rubber, measure 17 in (432 mm) wide and 47 in (1194 mm) long, with each carriage assembly weighing 1100 lb (499 kg). Designed to leave a minimal impression on sensitive surfaces, the booms operate with a ground contact pressure of 9.2 psi (63.4 kPa) for the S-60 and 9.7 psi (66.9 kPa) for the S-65.
Trax models’ four-point track system works in conjunction with Genie’s active oscillation axle system, which senses the terrain and adjusts the axle position based on ground conditions, and Genie’s positive traction drive system, which maintains equal power to all tracks even if one track loses traction. During travel, the four-point system’s tracks flex 23° up and down to accommodate the contour of the landscape, helping to provide a smooth ride during operation and travel.
The S-60 model offers 500 lb (227 kg) lift capacity at the maximum horizontal outreach of 50.9 ft (15.5 m) up to a working height of 66 ft (20.1 m). The S-65 model provides a lift capacity of 500 lb (227 kg) at the maximum horizontal outreach of 56.2 ft (17.1 m) to a working height of 71 ft (21.6 m).
Undercarriages are constructed from high-grade steel and feature fully sealed, greaseless bearings for minimum maintenance. The four-point track system also features an easy-grease tensioning system for track adjustment, and V-shaped, self-cleaning pads that help to limit debris buildup during operation.
Loegering’s Quad Track System is available as an aftermarket option for both the S-60 and S-65 telescopic booms. This flexible track system is a set of four track undercarriages that fasten directly onto a boom’s standard wheel hubs in place of the tires. According to Genie, the entire system can be put on or taken off the booms in less than 4 h, so tracks can be bolted on when needed or removed when regular wheeled operations are preferred. This option increases machine width to 107 in (2718 mm), which may require special oversized load transport permits.
