Mobile hydraulic equipment—excavators, cranes, boom lifts, agricultural machinery, and forestry harvesters—requires fluid power to be delivered to actuators that move relative to the machine frame. Boom cylinders that raise and lower, attachments that rotate, and steering axles that articulate all create hydraulic hose routing challenges that, if improperly addressed, lead to hose fatigue, abrasion failure, and hydraulic fluid spills. Hose reels and swivel joints provide the controlled hose management and continuous rotary fluid transfer that mobile equipment demands for reliable, long-term hydraulic system operation.
Spring-Return and Motor-Driven Hose Reels
Hose reels store and dispense hydraulic hose in a controlled coil, paying out hose as the equipment extends and retracting it as the equipment returns. Spring-return reels use a pre-tensioned spring motor that automatically retracts hose when tension is released—ideal for applications with moderate extension lengths and frequent retraction cycles. Motor-driven reels—hydraulic, electric, or pneumatic—provide powered retraction for heavy hose assemblies or long extension lengths where spring force alone is insufficient.
The Hose Reel product line spans both spring-return and powered configurations, with custom sizing for hose diameters from 1/4 inch to 2 inches and extension lengths to 100 feet or more.
Swivel Joints for Continuous Rotary Motion
When hydraulic fluid must be transferred to a continuously rotating component—such as a crane upper structure rotating 360 degrees on its carrier, or an excavator attachment rotating on its swivel—a rotary swivel joint provides the fluid interface. Multi-passage swivel joints route multiple hydraulic circuits (pressure, return, case drain) through a single rotating assembly, with high-pressure seals between stationary and rotating elements that maintain leak-free operation through millions of rotation cycles.
The Hydraulic Swivel Joint is available in configurations from single-passage to eight-passage designs, with pressure ratings to 6,000 psi and options for integrated electrical slip rings for combined hydraulic and electrical signal transmission.
Articulation Point Hose Routing
Hose routing across articulation joints—the pivot point between an articulated loader’s front and rear frames, or the boom pivot on an excavator—must accommodate both angular rotation and lateral displacement. Improper hose length or routing at articulation points causes hose stretching, kinking, or abrasion against adjacent structure.
The Hose Bending Machine helps fabricate pre-formed hose assemblies with the correct bend geometry for articulation installations, minimizing installation stress and extending hose service life.
Protective Sleeving and Abrasion Resistance
Hoses routed through reels and across articulation points experience concentrated abrasion at contact points with reel flanges, guide rollers, and machine structure. Protective sleeving—nylon, polyester, or steel spring guard—adds an abrasion-resistant outer layer at critical wear points. The Nylon Protective Hose Sleeve provides lightweight, flexible protection that conforms to hose movement while preventing direct rubber-to-metal contact.
