The HEKING HK300SD is a 30-ton swamp excavator developed for excavation and construction work where conventional excavators may not be suitable for soft, wet or difficult-access terrain. It combines a hydraulic excavator upper structure with an amphibious pontoon-based undercarriage configuration for applications including wetland construction and river dredging.
For contractors, engineering companies and project owners, the main value of the HK300SD is its configuration for working in environments where ground conditions are an important equipment-selection factor. The machine has a specified ground pressure of 0.14 kg/cm² and a pontoon size of 8,285 × 1,800 × 1,700 mm.
The HK300SD has an operating weight of 30,000 kg and a maximum digging reach of 10,186 mm. Its standard bucket capacity is 0.8 m³, while the product information also identifies a 0.8–0.9 m³ range. Buyers should confirm the final bucket configuration and specification when requesting a quotation.
The machine is intended for professional project use rather than general-purpose consumer applications. Its listed applications include river dredging, wetland construction, oil and gas pipeline projects, flood control and coastal engineering.
The HK300SD uses an amphibious pontoon arrangement designed for wetland and soft-ground operating environments. The supplied specification lists each pontoon at 8,285 mm in length, 1,800 mm in width and 1,700 mm in height.
The pontoon configuration is an important part of the machine's suitability for projects involving wetlands, marshes, shallow water and other areas where conventional ground conditions are difficult.
The specified ground pressure is 0.14 kg/cm². For project procurement, this value is particularly relevant when evaluating equipment for soft-ground operations because ground interaction can affect access and machine suitability.
Actual site suitability should be evaluated against the project's soil, water depth, terrain, access and operating conditions.
The HK300SD uses a variable plunger pump system with a maximum displacement of 2 × 112 cm³/r, maximum flow of 2 × 240 L/min, and working pressure of 32 MPa.
The supplied configuration includes a Doosan T5V112 pump, PARKER AV280 valve, Eaton 11020268501 swing motor and two DOOSAN TM60VC travel motors.
The machine has a maximum digging reach of 10,186 mm, maximum digging reach on ground of 10,163 mm, maximum digging depth of 3,201 mm, maximum vertical digging depth of 10,163 mm, maximum digging height of 7,027 mm, and maximum dumping height of 6,928 mm.
The maximum bucket digging force is specified as 122.85 kN, while maximum arm digging force is 97.64 kN.
The HK300SD swamp excavator is specified for several project environments where amphibious access and excavation capability are required.
The HK300SD can be used for river dredging projects where excavation work is required around wet or water-affected terrain. Its amphibious configuration and approximately 10.19 m maximum digging reach support project requirements involving access to areas that may be difficult to approach with standard excavators.
Wetland construction can involve saturated soils and soft working surfaces. The HK300SD is configured as a swamp excavator for these conditions, with its pontoon undercarriage and specified low ground pressure.
The product information identifies oil and gas pipeline projects as an application. The machine can be considered where excavation and construction work must be carried out across wetland or soft-ground sections of a project.
Flood control is another listed application. Contractors can evaluate the HK300SD for excavation work associated with water-management and flood-control projects, subject to specific site conditions.
The HK300SD is also listed for coastal engineering projects. Buyers should assess local water depth, ground conditions, access requirements and the complete project method before selecting the machine configuration.
