Bomag’s new RS 650-2 recycler/stabilizer is equipped with a new cab design that reduces operating noise levels and improves comfort with an adjustable air-suspension seat.
The operator’s station, including the seat, control lever and display, slides the full width of the cab and rotates 45-degrees in either direction to give direct sightline to the sides of the machine.
The entire cab rises to a working position for excellent visibility around the machine and lowers to 4.1-metres to simplify transport.
Bomag also upgraded from an analogue to full colour touchscreen for the control centre.
The new 18-cm monitor allows the operator to control rotor depth and speed, gate positioning, emulsion and water injection rates, as well as quick diagnostics of machine issues.
The touchscreen offers quick navigation through operating panels and is the same display as the Bomag RS 460 for continuity of operation between machines.
Increasing safety at the jobsite, the standard enhanced camera system features two camera views to the left and right of the machine as well as two for monitoring the working area to the front and rear for 360-degree coverage.
As well, two additional fore/aft cameras mounted on the rotor housing allow operators to see rotor gate positioning as well as material gradation. Bomag also equipped the cab with two 25-cm monitors — one for the 360-degree camera system and one for rotor feed.
“These are significant upgrades to the RS 650-2 design to improve operator comfort and productivity,” said Randy King, Recycler/Stabilizer Business Development Manager for Bomag. “The new controls offer simple, intuitive machine operation, and our new camera system improves visibility on a machine that already offered great visibility.”
FlexMix design
The RS 650-2 offers efficient soil stabilization and asphalt reclamation on a wide range of projects, including landfill construction, new developments, oil field pads, large industrial construction, parking lots, highways and airports. The Bomag-exclusive FlexMix design delivers high-quality mixing results with optimized costs.
In addition to the front and rear gates, the design features a third adjustable gate that keeps material engaged with the rotor longer to offer better material gradation and compaction.
An articulated frame machine, the RS 650-2 delivers a tight steering radius that offers excellent manoeuvrability in tight spaces, such as working in cul-de-sacs.
The steerable rear axle enables four different steering modes to aid in working close to structures, so daily production targets can be met. Delivering optimum ground contact, the axle also oscillates up to 15-degrees for improved traction. These drive design advantages —along with 4×4 all-wheel drive with anti-slip control (ASC) — allow the machine to excel when completing difficult stabilization projects.
Hydrostatic rotor drive
The new RS 650-2’s hydrostatic rotor drive provides continuously variable rotor speeds from 104 to 140 rpm to minimize tool and rotor wear and meet site conditions. Its hydrostatic overload protection system automatically absorbs load shock when an obstruction is encountered to prevent damage to the gearbox, increasing uptime.
“It’s a strong system that keeps the crew working,” King said. “Hitting obstructions with machines using either belt or chain rotor drive often results in damage that can leave a machine down for hours.”
The new recycler/stabilizer is powered by a 653-hp, 8-cylinder engine that meets Tier 4 Final emissions standards. The combination of power and traction gives the new RS 650-2 the ability to push an emulsion tanker while pulling a water truck at the same time.
Regardless of working or engine speed, the hydraulic travel system delivers impressive torque.
Furthermore, the RS 650-2 recycler/stabilizer features Bomag’s BMS15 quick-change tooth/holder system. A maintenance-free design offers easy handling, and the positive connection between tooth and holder absorbs high mixing forces.
The holder quickly bolts on with only 102 nm torque. High-wear-resistant steel delivers a long service life to lower owning and operating costs.
