51 52 55 Tonne Large Hydraulic Crawler Excavator Sy550hb-S Sy550h-S Heavy Duty Digging Mining Rock Bucket 3.1- 3.6 M3 300 Kw 6wg1xksc-01 Engine Ribber Frontless

1.More Durable and Reliable

NM400 wear-resistant steel is used for bucket side plates and toughness plates to improve bucket wear resistance.
For mining-type working devices, the key supporting parts are integral casting and forging structures, and the average stress is 10-13% lower than that of competing
H swing arm and 14-30% lower than that of bucket rod.
Large box-type double-support rotary platform, with an increase of bearing capacity by 30%.
The 100-ton four-wheel area is adopted, the shaft diameter is increased to reduce the bearing surface pressure, and the bearing capacity is increased by 30%.
Based on durability test system for excavator parts in China and in conjunction with internationally renowned research institutions,
research on the life of parts has been carried out to comprehensively improve the life of core parts, doubling the service life of pumps, valves, oil cylinders, reducers, oil tanks, cab machines and other parts.
The heat radiation efficiency is increased by 20%, the working temperature of the system is reduced by 8-10°C compared with that of ordinary excavators, the adaptability to high temperature environment is greatly improved, the service life of rubber parts is increased by 30%, and the energy saving rate is 30% higher than that of the integral heat radiation system.

With right-angle plate-fin fins, the air duct area is greatly increased, and the heat radiation efficiency is 20% higher than that of ordinary radiators; the pressure resistance of the radiator is improved by 10%, and the service life is longer.

Rigorous machine test

2, More intelligent and comfortable
3, More efficient and fuel saving
The ICT-integrated control technology mainly includes E-P, P-V, FD, and ECA technologies, i.e. matching technology between engine and main pump, main pump and main valve, flow distribution technology, electronic control auxiliary technology, swing arm unpowered lowering technology, and independent oil and water radiation control. The efficiency of the machine is equivalent to that of competing products, but the fuel consumption is reduced by 5-13%.

4, Low maintenance costs
Through years of market verification, the excavator's maintenance cost is reduced by 50% and the customer maintenance period is doubled; Maintenance costs are 40% lower than those of competing products.
