Roller Combo Hoist Brochure

www. .comROLLER- COMBO™Hoists®• For loads to 34 tons• Exclusive roller principle provides more breakaway power• Subframe mountedPatent #4,741,5762Advanced DesignEvery Roller-Combo includes a full-length sub-frame, engineered to provide stability and added strength to the truck frame. Channel-type subframes are used on all models. This, along with the square box frame and far-forward lifting point on the hoist, adds stability and rigidity not possible with older hoist designs. Crysteel’s super heavy-duty, angle-type rear hinge is another built-in quality feature of every subframe. The rear hinge is standard with welded pins. Removable pins or greaseless composite bearings are available.Efficient HydraulicsHigh-Pressure Hydraulics: Our high-pressure hydraulics deliver maximum efficiency. Our smaller pumps and cylinders weigh less but do more. That’s why the aircraft industry uses high-pressure hydraulics exclusively. And it’s why you’ll get superior performance from your Crysteel hoist.Low-Pressure Hydraulics: Crysteel’s three low-pressure (2000 psi) Roller-Combo Hoists provide power and the capability to match up perfectly with your low pressure central hydraulic system. Built with the same high quality tubing and high pressure seals that are proven on all Crysteel cylinders, you’ll get years of trouble-free operation you wouldn’t have believed possible. Composite BearingsCritical rotating pivot points on the Roller-Combo use greaseless Teflon® composite bearings which never need lubricating. They rotate on stainless steel shafts and are completely impervious to corrosion. They are maintenance-free and will extend the life of your hoist while helping ensure smooth operation.Less Weight, More StrengthAll Roller-Combo fabricated parts are made from high-strength, low alloy steel. All shafts and tubing are cold-drawn high-strength steel. It adds up to weight savings of up to one-third without sacrificing strength.Premium Quality CylindersCrysteel cylinders are designed to last. That’s because they’re made from high-strength steel tubing and feature chromed shafts, close-tolerance pistons and high-pressure seals. An internal cylinder bypass protects the system. Pressure is never more than is needed to lift the load, but full pressure is always available instantly. Total Control and FlexibilityCrysteel’s exclusive reservoir mounted valve provides the flexibility and features you want and demand. Power beyond port provides the flexibility to expand the system to power other equipment or add a filter kit or both. Proven features like built-in load check, voluminous flow characteristics and feather touch metering control help you control the load exactly the way you desire. Crysteel’s locking lever pedestal control and SEALED cable provide the finishing touch and worry-free operation.The Crysteel Roller-Combo Hoist is made in six sizes for dump bodies from 8' to 17' long. Take a look at these quality Crysteel features you’ll find standard on every Roller-Combo Hoist:2145638Reasons Why the RolleR-Combo Hoist offers top Performance & Reliability3More Lifting PowerCrysteel’s patented “Roller-Combo” feature provides almost a third more breakaway power for lifting heavy loads with power to spare at the end of the cycle.Graph shows that the Roller-Combo always provides more power when you need it most . . . at breakaway. Power remains steady throughout the critical dumping cycle, staying well above requirements all the way. Built for Years of ServiceModern technology provides the solid foundation on which we designed and built the Roller-Combo Hoist. Rugged high strength steel and proven gear pumps combined with UHMW wear plates, maintenance-free Teflon® composite bearings, o-ring porting, and Crysteel’s CAD-CAM engineering experience provide you with the best possible hoist money can buy.The Crysteel Roller-Combo Hoist is made in six sizes for dump bodies from 8' to 17' long.

Take a closer look at Crysteel’s Roller-Combo Hoist First half of dump cycle illustrated.How the RolleR-Combo WorksCrysteel’s exclusive Roller-Combo feature is the secret to the Roller-Combo’s power and efficiency. At the start of the lift cycle, the short arm position of the roller allows almost a third more breakaway power to start heavy loads. As the load rises, the roller moves smoothly along its track increasing the effective length of the upper hoist arm. When the roller reaches the end of the track, the hoist automatically becomes a scissors-type hoist, with enough power to easily finish the dump cycle.Reasons Why the RolleR-Combo Hoist offers top Performance & ReliabilityBreakaway TorqueSold by:ROLLER-COMBO™ HOIST CRYSTEEL MANUFACTURING, INC.Lake Crystal, MN • 1-800-533-0494 • FAX 507-726-2559 www.crysteel.com • E-mail crysteel@tbei.com©2013 Truck Bodies & Equipment International, Inc.Printed in USA 700885FCrysteel High-Pressure Hoists Compatible With Load Sensing SystemsThe Roller-Combo Hoist is especially suited to closed-center, load-sensing hydraulics using variable displacement piston pumps. The high-pressure hydraulics maximizes the efficiency of closed-center load-sensing over low-pressure hydraulics. This is because the hoist’s hydraulic cylinders have low volume displacement. This can result in saving up to 20 horsepower on a typical highway department truck equipped with a hoist, sand spreader and snowplow.Specifications subject to change.*Capacities based on water-level load, 12" overhang, 50° dump angle, and includes body weight.CAUTION: The combined weights of truck, body, hoist and load must not exceed the truck’s Gross Vehicle Weight rating.Roller-Combo Patent No: 4,741,576ROLLER-COMBO HOIST LOAD CAPACITY IN TONS*Model NumberNTEA Performance ClassBody Length (ft.)8 9 10 11 12 13 14 15 16 17RC 540 40 18.4 15.8 13.8RC 650 50 26.6 22.8 19.9 17.7RC 750 50 19.7 17.2 15.3RC 860 60 25.7 22.4 20 17.9RC 690 90 34.0 30.9 28.4 26.2 24.3RC 6100 100 34.9 32.2 29.9 27.9 ROLLER-COMBO HOIST SPECIFICATIONSModel Number RC 540 RC 650 RC 750 RC 860 RC 690 RC 6100NTEA Performance Class 40 50 50 60 90 100Double-Acting Cylinder Standard Standard Standard Standard Standard StandardNumber of Cylinders 1 1 1 1 2 2Cylinder Bore and Stroke (in.) 5 x 21B\\, 6 x 21B\\, 7 x 21B\\, 8 x 21B\\, 6 x 32Z\\x 6 x 32Z\\xChromed Shaft Dia.
