Equipment Overview JLG 400S 4WD Telescopic Boom Lift

Why This Boom Lift Stands Out

• 1,000 lb Restricted Capacity: Allows multiple workers to bring heavy tools and materials (like steel beams or HVAC components) into the basket, drastically improving jobsite efficiency.
• Telescopic Straight-Boom Design: Delivers superior horizontal outreach (33 ft 3 in) compared to articulating models, perfect for reaching across obstacles or expansive job sites.
• 4-Wheel Drive (4WD) & Foam-Filled Tires: Ensures maximum traction in mud and gravel while completely eliminating the costly risk of flat tires.
• 360° Continuous Swing: Provides unmatched jobsite coverage and maneuverability without needing to constantly reposition the machine’s base.
• Exceptional Gradeability: Capable of climbing up to a 45% grade, making it ideal for sloped terrain and heavy civil projects.
