The HEKING HK300SD is a 30-ton amphibious excavator configured for excavation, dredging and construction work in wetland and soft-ground environments. Its design combines an excavator upper structure with a dedicated amphibious pontoon undercarriage, allowing the machine to be used in operating environments where ground conditions can restrict the mobility of conventional excavators.
The HK300SD is intended for project work including river dredging, wetland construction, oil and gas pipeline projects, flood control projects and coastal engineering. These applications commonly require excavation equipment to operate around water, saturated ground, marshland or other areas where conventional access can be difficult.
For project buyers, the machine's key selection characteristics include its 30,000 kg weight, 0.14 kg/cm² listed ground pressure, 10,186 mm maximum digging reach, 0.8 m³ standard bucket capacity and amphibious pontoon configuration.
The product is therefore positioned as a project-oriented excavator for contractors, engineering companies, equipment importers and other professional buyers evaluating machinery for wet and soft terrain applications.
The HK300SD uses an amphibious pontoon-based lower structure rather than a conventional excavator undercarriage. The supplied specification lists a pontoon length of 8,285 mm, pontoon width of 1,800 mm and pontoon height of 1,700 mm.
The listed overall dimensions are 10,747 mm in length, 5,742 mm in width and 3,759 mm in overall height. The platform ground clearance is listed as 1,936 mm, while minimum ground clearance is 1,126 mm.
These dimensions are important during project planning because transport access, working width, site entry conditions and operating space should be evaluated before procurement.
The HK300SD is based on the operating concept of an excavator mounted on an amphibious pontoon undercarriage.
During excavation work, the hydraulic system drives the boom, arm, bucket, slewing system and travel system. The supplied specifications identify a variable plunger pump configuration with a maximum displacement of 2 × 112 cm³/r and maximum flow of 2 × 240 L/min. The listed working pressure is 32 MPa.
The machine's listed swing speed is 11 rpm. The travel system uses two DOOSAN TM60VC variable-plunger travel motors, with a listed maximum high/low travel speed of 3.3/2.17 km/h.
For excavation performance, the supplied data lists:
Maximum bucket digging force: 122.85 kN
Maximum arm digging force: 97.64 kN
Maximum digging reach: 10,186 mm
Maximum digging depth: 3,201 mm
Maximum digging height: 7,027 mm
Maximum dumping height: 6,928 mm
These figures describe the specified operating configuration and should be evaluated against the actual working method, attachment, site conditions and project requirements before procurement.
The HK300SD has a listed ground pressure of 0.14 kg/cm². For wetland and soft-ground projects, ground pressure is an important equipment-selection consideration because site bearing conditions can significantly affect equipment access and mobility.
The actual suitability of the machine for a particular site should be confirmed against the project's ground conditions, water depth, access route, working method and required operating area.
With a listed operating weight of 30,000 kg, the HK300SD is configured for projects requiring a larger excavator platform than smaller amphibious machines.
Its 0.8 m³ standard bucket capacity and 118 kW engine configuration provide the specified baseline for excavation applications. Attachment selection and working configuration should be confirmed according to the intended project.
The maximum digging reach is specified as 10,186 mm, while maximum digging reach on the ground is listed as 10,163 mm.
The machine also has a listed maximum vertical digging depth of 10,163 mm. These specifications can be relevant for riverbank excavation, dredging-related work and other projects where the excavator needs to work from a particular access position.
The HK300SD uses a hydraulic configuration specified with a variable plunger pump, PARKER AV280 valve, Eaton 11020268501 swing motor and two DOOSAN TM60VC travel motors.
The supplied engine options are Mitsubishi 4M50-TLC3J and Isuzu 6BG1TRP-03. The listed engine specification includes inter-cooled turbo configuration, 118 kW power at 2,000 rpm, 620 N·m maximum torque at 1,500 rpm, four cylinders and 4.899 L displacement.
The HK300SD is specified for several wet and water-adjacent project environments.
The HK300SD can be used for river dredging applications where excavation equipment needs to work in wet ground and around waterways.
For dredging procurement, buyers should confirm the required digging reach, excavation depth, bucket configuration, water conditions, access limitations and project-specific attachments.
Wetland construction projects can involve saturated soils and soft terrain that require equipment configured for conditions beyond conventional dry-ground excavation.
The HK300SD's amphibious pontoon configuration and listed low ground pressure make it applicable to wetland construction projects, subject to confirmation of actual site conditions.
The HK300SD is specified for oil and gas pipeline projects. Its application can be considered where pipeline construction or associated excavation work takes place across wetland or soft-ground sections.
Project procurement should confirm the required working width, reach, access route and attachment configuration before equipment selection.
The machine is also specified for flood control projects. Potential work areas may include wet ground and water-adjacent excavation environments where equipment access is an important consideration.
The actual machine configuration should be selected according to the excavation task and site conditions.
The HK300SD is specified for coastal engineering applications. Buyers planning coastal projects should evaluate the site's ground conditions, water environment, access requirements and required working envelope when confirming equipment suitability.

The supplied product information identifies an additional pontoon and spud as an optional configuration for deep-water applications.
This option should be discussed with HEKING during project evaluation when the machine is intended for deeper-water operating conditions.
Because water depth and site conditions are project-specific, buyers should provide the intended operating environment and required working conditions when requesting a technical configuration.
The HK300SD is configured with an amphibious pontoon undercarriage for applications involving wetland and soft-ground conditions. This configuration is directly relevant to projects where conventional excavator access can be constrained by ground conditions.
The 30,000 kg listed operating weight places the HK300SD in a larger amphibious excavator configuration suitable for projects requiring a substantial excavator platform.
The listed maximum digging reach of 10,186 mm provides a defined working envelope for project planning and equipment evaluation.
The specified ground pressure of 0.14 kg/cm² is a relevant technical characteristic for buyers evaluating equipment for soft terrain and wetland operations.
The specified applications include river dredging, wetland construction, oil and gas pipeline projects, flood control and coastal engineering, allowing the machine to be evaluated across several water-adjacent engineering environments.
The product information lists Mitsubishi 4M50-TLC3J and Isuzu 6BG1TRP-03 as engine options. The selected configuration should be confirmed during technical and commercial discussions.
The HK300SD should be evaluated according to the actual project rather than operating weight alone.
Before requesting a quotation, professional buyers should confirm:
Working environment and ground conditions
