STELLAR® 4421 TECHNICAL SPECIFICATION GUIDE

DEFINING CHARACTERISTICSRadio Control SystemEvery electric, on/off, or proportional 4421 comes standard with a radio remote control. Stellar is the market leader with standard radio remote controls.

Stellar® CDT™ (Crane Dynamics Technology™)Standard on 4421 proportional hydraulic crane, the Stellar CDT control system is revolutionary to the telescopic service crane market and EXCLUSIVE TO STELLAR. This system features capacity alert to the handheld crane remote and also features a Safe Mode to keep the crane and operator safe should a load indicating device fail to operate correctly.

Internal Extension CylinderNew to the 4421 crane is our new internal cylinder extensions system. Designed to the same standards of our larger cranes, you will find the looks and performance of our extension booms second to none.

Full Hydraulic Extension The 4421 crane offers an optional boom configuration of two hydraulic boom extensions. The 4421 crane come standard with a one hydraulic, one manual boom configuration.

Market Leading Boom ArticulationThe Stellar 4421 crane offers -10 degrees to +80 degrees. This gives the operator both easy reach to snatch block stowing and the best ability to load items into the load bed.

Quick Release Snatch Block StowThe Stellar quick release snatch block stow, is installed on the underside of the boom to easily stow your snatch block after use. Its 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.

Planetary WinchThe planetary winch on every crane manufactured by Stellar was designed to match the capacity and hydraulic control system. It lifts the maximum crane load and offers the smoothest and fastest speeds in the market today to help keep your productivity at max levels.

Strong Rotation SystemStellar uses a durable rotation system with a cast iron base and an internal mechanical stop to provide the most durable rotation system found in the industry.

Counterbalance ValvesEach cylinder on the Stellar 4421 crane feature counterbalance valves to prevent unintended cylinder movement should a hose break.

Greaseable Pivot BushingsEach pivot pin location on the 4421 crane includes bushings and grease zerks to provide for years of use.

Hexagonal BoomsStellar Industries made the hexagonal boom design famous in the telescopic service crane market. This design provides for a stronger and better aligning boom than competitive square boom design.

Bar Style Anti-Two BlockThe 4421 crane is equipped with a low profile bar style anti-two block system that allows for easy access to the tightest lifting locations.
