Description
The JLG X770AJ Compact Crawler Boom Lift is a precision-engineered, high-reach solution designed to conquer confined spaces and tough terrain with ease. Compact yet commanding, it squeezes through standard double doors while offering an unrestricted platform capacity of about 500 lb and reaching heights up to 77’ 5″ with a 43′ horizontal outreach for versatile access. Its intelligent features include drive-speed control, auto-leveling, and a regenerative valve on the telescopic cylinder that boosts operational speed by up to 50%. The narrow crawler footprint of the JLG X770AJ delivers stability and maneuverability where traditional boom lifts can’t go.
