The JCB 510-42 is built for contractors who need five-tonne-class lifting performance without relying on stabilizers. It delivers a 10,000 lb maximum lift capacity, reaches 42 ft high and provides 28 ft of forward reach, making it useful for structural work, masonry and material placement across active jobsites. At maximum height it retains 6,000 lb of capacity, while 2,500 lb remains available at full reach.

A 109 hp JCB EcoMAX Tier 4 Final diesel engine provides power for lifting and travel, while front-wheel, all-wheel and crab steering help the machine maneuver between structures and around congested work areas. Rear axle stabilization and frame sway support controlled lifting, and proportional single-lever boom controls help operators make precise adjustments when placing loads at height. Its ability to achieve full rated capacity without stabilizers can also reduce setup time when the machine is moving frequently around the site.
