Product Description
Power transmission system The engine is paired with a ten-speed gearbox, and the double-reduced axle is adapted to high-load tires, which can carry a maximum of 20t of counterweight to the field. 470L extra large aluminum alloy fuel tank increases cruising range by 45%.
Proprietary composite hydraulic control technology, higher efficiency Dual-variable pump + post-valve compensation load-sensitive system, dual-pump automatic splitting and merging control, can achieve any combination of working conditions, and the operating efficiency is industry-leading. The post-valve compensation technology is adopted to reduce the throttling loss of the hydraulic system, and improve the micro-movement and smooth operation of the hoisting operation, realizing the perfect combination of economical efficiency and precise control.
Finely crafted - more exquisite details The appearance details of the whole machine are newly designed, and the interior of the cab is comprehensively improved: dust-proof, noise-reducing and highly airtight two-chamber, Seiko high-gloss metal brushed texture decoration, new high-precision length and angle sensor, molded aluminum alloy arm head junction box, etc.
Intimate and humanized - more convenient to use Large field of view hoisting monitoring mirror, hoisting work is safer; one-piece cast counterweight logo, counterweight combination identification is higher, hoisting is safer; jib double-pointed pin shaft design, shaft threading is more convenient; lifting hook is easy to wear The rope system eliminates the need to disassemble the wedge sleeve and saves 48% of the rope threading time.
