Performance Overview
The Commander 2000 is rated for lifts up to 2,000 lb (907 kg). Load capacity decreases gradually at longer boom extensions, but the telescoping design provides exceptional versatility for reaching over tanks, rails, and walls. The crane’s 360° rotation and quick-mount winch bracket make it ideal for manufacturing, marine, wastewater, and general industrial use.
