600 Series telescopic boom lifts have a powerful combination of performance and reliability so you can conquer all your worksite challenges. Lift heavier loads with increased platform capacities and improve your access to overhead tasks with enhanced horizontal outreach.

Mud, sand and rough terrain are no match for the standard oscillating axle and 45% grade climbing ability on a 600 Series telescopic boom lift. Plus, our Hi-Capacity telescoping lifts allow you to push the envelope without compromise, offering three capacity zones, each rated for three occupants and tools.

Features May Include: 

• Utilizes three working zones for enhanced capacity; up to three workers and tools can fit onto the platform.  
• Delivers a zero calibration automatic load sensing system that eliminates the need to use external weights to calibrate the machine.  
• Upgraded light panel for more visibility in the sun and chassis tilt alarm that alerts the operator when the machine is on a slope that exceeds 5 Degrees.
