BENEFITS & FEATURES

QUALITY

It is an all-terrain crane with 250t lifting capacity, 7 section 75m boom, andfeatures dual engine power system, wireless remote control of all motions, standard anti.electromagnetic interference module, and the brand-new iCab, with driving and operationcomfort fully upgraded.

DIMENSIONS

All axles equipped with hydro-pneumatic suspension with hydraulic lockout, height adjustable up by 165mm and down by 125mm. Driving comfort and lateral stability is therefore guaranteed on rough terrains and conditions.

USER EXPERIENCE

ROOTCLOUD T-AMS Pro device comes as standard to realize GPS trajectory, machine status, maintenance management, alarm management, on computer or mobile MachineLink+ platform, by remote control of cranes. This telematics package greatly boosts efficiency of customer fleet management and helps provide better after-sales services.

SAFETY

Anti-electromagnetic interference module, allowing the crane to work normally in strong electric field or strong magnetic field (≤20v/m and >500m away from interference source), including cluster construction of high-power equipment, and the vicinity of multiple interference sources including high-voltage lines, broadcasting base stations, power plants, aluminum plants, radar stations, military bases or mobile communication stations. Service brake: dual circuit, air servo on all wheels, caliper disc brake and double air chambers on axles 1and 2. Parking brake: functioning at axles 2, 3, 4, and 5 by spring-loaded air chamber. Assisting brake: transmission hydraulic retarder, safety assured when driving down long slopes. Hydraulic system reliability is guaranteed by balance valve, relief valve, and two-way holding valve. Length & angle indicator and pressure sensor are equipped to show real-time operation status. Hazardous motions are cut off automatically with buzzer alarming.

COMPONENTS

Single cylinder pinning mechanism 7 boom sections telescoping via single cylinder pinning mechanism, achieving variable length combinations for stronger performance or higher efficiency.

ECONOMY

CAN BUS instrument, IP65, low power consumption of 5W. Multi-functional display system, LCD screen of adjustable contrast ratio.
