Stellar 3315, 4421 Telescopic Cranes

June 6, 2014

Models 3315 and 4421 telescoping boom cranes have maximum lifing capacities of 3,200 and 4,000 pounds, respectively. An internal cylinder-extension system meets the standards of Stellar’s heavy-duty cranes. The Stellar CDT system uses multiple sensory indicators to engage and communicate with the crane operator when approaching maximum capacity. Warnings include LED lights and pulsating vibrations that are transmitted through the handle of the hand-held remote control. Some CDT systems have Boost Mode to operate at 118 percent of capacity for a short period of time. A safety mode allows the crane to function when a safety feature is damaged or malfunctions.
