The Hyundai R305 is a 30-ton excavator made by Hyundai (Jiangsu) Engineering Machinery Co., Ltd. With a working weight of 30,200 kg, it’s super stable. It’s powered by a Cummins C8.3-C engine, which cranks out 198 kW at 1900 rpm. This six-cylinder, four-stroke engine is turbocharged, intercooled, and direct injection, with a displacement of 8.3 liters. It’s both powerful and reliable, and it can handle the quality of fuel available in China, cutting down on downtime caused by fuel issues.
The hydraulic system is fitted with two variable axial piston pumps, each with a maximum flow of 252 liters per minute. The main pump’s overflow setting is at 34.3 MPa, giving the machine some serious operating power. It delivers a bucket digging force of 192 kN and an arm digging force of 136 kN. The rotation speed is 10.2 rpm, and it can travel at speeds of 5.2 km/h or 3.1 km/h. With a climbing ability of up to 35 degrees, it can handle a wide range of tough working conditions with ease.
The Hyundai R305 has some standout design features. It comes with a 1.38m³ bucket, perfect for large-scale earthwork. The boom length is either 6250mm or 5600mm, and the arm length can be heavy-duty at 2500mm or extended to 3570mm. This gives it a wide operating range, with a maximum digging radius of 10820mm and a maximum digging depth of 7500mm. For transport, it measures 10560mm in total length, 3200mm in width, and 3300mm in height, making it easy to move around.
The maintenance-free AC motor and fully sealed, maintenance-free battery really cut down on the need for upkeep and the associated costs. Plus, you can add optional safety features like smart reversing cameras and collision warnings, which boost safety in all kinds of operations. This makes the Hyundai R305 a great fit for material handling in warehouses, logistics, ports, manufacturing, and other industries.
The equipment also comes with an advanced CAPO system, which fine-tunes the performance of the engine and main pump. It includes features like automatic idling and flow regeneration for the boom and bucket arm, which boost operating efficiency and fuel economy. This makes it perform exceptionally well in mining, large-scale construction, and other demanding fields.
