4421 Hydraulic Service Crane


4,000-lb Capacity with 21′ of Reach

The Stellar® 4421 Hydraulic Truck Crane helps construction companies, public utilities, municipalities, agriculture operations and more handle their lifting needs.

  • Selection. Available in electric and hydraulic models.
  • Proportional Radio Remote. Can be operated with the handheld CDT™ Radio Remote Control System, which includes a capacity alert communication system and a safe mode function. The crane control system gives operators precision control while allowing them to stand in the best possible position to achieve their job efficiently.
  • Planetary Winch. Featuring a hydraulic or mechanical brake system, it lifts the maximum crane load and offers the smoothest and fastest speeds in the market today for maximum productivity.
  • Superior Boom Articulation. Stellar Hydraulic Cranes make loading easier with industry-leading -10 degrees to +80 degrees articulation.
  • Full Hydraulic Extension. No manual extension is required for hydraulic models. A configuration with one hydraulic and one manual boom is standard, and an optional boom configuration of two hydraulic boom extensions is available.
  • Internal Extension Cylinder. Delivers the same extension boom performance as our larger cranes.
  • Quick-Release Snatch Block Stow. Easily stow your snatch block on the underside of the boom after use. The unique design gently releases the snatch block for use when the boom is raised at close to 60 degrees to ensure a safe and orderly deployment.
  • Strong Rotation System. The cast iron base and internal mechanical stop provide the most durable rotation system found in the industry.
  • Counterbalance Valves. Included on each cylinder to prevent unintended cylinder movement should a hose break.
  • Greaseable Pivot Bushings. Each pivot pin location includes bushings and grease zerks to simplify maintenance and help ensure years of use.
  • Innovative Boom Design. Stellar’s boom design delivers a stronger and better-aligning boom than the square booms of other brands.
  • Bar-Style Anti-Two Block. The low-profile, bar-style anti-two block system allows for easy access to the tightest lifting locations.
  • Certified. Meets ANSI B30.5 and OSHA 1910.180 specifications.
