Category Overview

Amphibious excavators combine an excavator upper structure with a pontoon-based undercarriage configuration intended for work where conventional tracked equipment may face challenging ground or water-access conditions. The supplied HEKING range covers 15,000 kg to 40,000 kg class machine weights by individual model, with model-specific hydraulic, dimensional, digging and undercarriage configurations.
This category is relevant to contractors, dredging companies, environmental engineering companies, wetland contractors, water management contractors, infrastructure contractors, equipment dealers and other professional buyers evaluating specialized excavation equipment.

What Is This Product Category?

Amphibious excavators are specialized excavating machines configured with floating or pontoon-type undercarriage systems. Their design combines excavation capability with an undercarriage intended for wetland and water-access working conditions.
The supplied HEKING models use different pontoon dimensions, track configurations, ground clearances, hydraulic systems and working ranges. Configuration therefore needs to be evaluated according to the selected model and project requirements rather than treated as a single category-wide specification.

Pontoon-Based Undercarriage

The supplied models incorporate pontoon undercarriage configurations. HK150SD and HK200SD specify four travel motors, strengthened track shoes and chains, and large buoyancy-related undercarriage characteristics. HK150SD also specifies a hydraulic extendable undercarriage, while HK200SD provides a manual extendable undercarriage with hydraulic extension available as an option.

Reinforced Track and Chain Configuration

The supplied undercarriage information includes strengthened track shoes and chains. HK300SDA additionally specifies 40Cr rollers and Q345B material for its undercarriage structure, with stated hull thicknesses of 6 mm at the top, 6 mm at the side and 8 mm at the bottom.

Extendable Undercarriage Configurations

Undercarriage width can vary by model. HK150SD specifies a track gauge of 2050–3100 mm, while HK200SD specifies 2598/3398 mm. HK300SDA specifies a minimum and maximum overall width of 4719/5519 mm. These model-specific configurations should be considered when evaluating access, stability and transport requirements.

Model-Specific Hydraulic and Excavation Systems

The supplied range uses different engine, pump, valve, swing motor and travel motor configurations. Digging reach, digging depth, digging height, ground pressure and travel performance also vary by model and should be confirmed against the technical information for the selected machine.

Product Range

The current HEKING amphibious excavator collection consists of five supplied models:
HK150SD
HK200SD
HK300SD
HK300SDA
HK400SD
The models range from the supplied 15,000 kg HK150SD to the supplied 40,000 kg HK400SD. Individual configurations differ in engine system, hydraulic system, pontoon dimensions, track configuration and digging performance.

River Dredging

HK300SD is explicitly supplied with river dredging as an application. The category can therefore support river-related excavation and dredging requirements where the selected model and configuration are suitable.

Wetland Construction

HK300SD is supplied for wetland construction. Other models may require individual technical evaluation according to project conditions and configuration.

Flood Control Projects

HK300SD is explicitly associated with flood control projects in the supplied product information, making it relevant for specialized excavation work connected with flood management infrastructure.

Coastal Engineering

HK300SD is also supplied for coastal engineering applications. Project conditions, machine configuration and required working range should be evaluated before procurement.

Oil and Gas Pipeline Projects

HK300SD is identified for oil and gas pipeline projects. Suitability should be confirmed according to the specific site conditions, excavation requirements and selected configuration.

Operating Environments

Amphibious excavators are intended for specialized operating environments where wet or difficult ground conditions are important considerations. Relevant environments for the supplied category include wetlands and other water-access working areas.
The pontoon dimensions, track gauge, overall width, ground clearance and ground pressure differ between the supplied models. Buyers should therefore evaluate the actual site conditions against the selected model rather than applying one operating limit to the entire category.

Operating Weight

Operating or total weight is model-specific. The supplied figures include 15,000 kg for HK150SD, 20,000 kg for HK200SD, 30,000 kg for HK300SD, 36,000 kg total weight for HK300SDA and 40,000 kg for HK400SD.

Engine and Hydraulic System

Engine models, engine power, hydraulic pump configuration and working pressure vary between the supplied models. These parameters should be evaluated according to required excavation performance and project conditions.

Ground Pressure and Ground Clearance

Ground pressure and ground clearance are important considerations for wetland and soft-ground applications. The supplied models have different values, so buyers should review the selected model's specification rather than using a single category-wide value.

Pontoon and Undercarriage Configuration

Pontoon length, pontoon width, pontoon height, track gauge and overall machine width vary between models. Extendable undercarriage configurations are also model-specific.

Working Range

Maximum digging reach, digging depth, digging height and dumping height vary between the supplied models. Buyers should compare the selected model's working range with the required excavation geometry.

Travel and Mobility

Travel speed, gradeability and tractive effort are supplied as model-specific parameters. These should be considered together with site access, ground conditions and project mobility requirements.

Attachments and Configuration

Attachment requirements should be confirmed according to the intended application. The supplied category information does not establish a universal attachment package for all five models.

Product Selection

Selecting an amphibious excavator should begin with the actual project environment and required work function. Buyers should evaluate:
The type of excavation or engineering work required
Wetland and water-access site conditions
Required machine size and working range
Ground pressure and ground clearance requirements
Pontoon and undercarriage configuration
Track gauge and transport dimensions
Engine and hydraulic system requirements
Required digging reach and depth
Travel and mobility requirements
Attachment and configuration requirements
Transport and delivery conditions
For quotation, buyers should identify the intended application and provide the relevant project conditions so the appropriate supplied model can be evaluated.

Model Selection Considerations

The five supplied models differ materially in machine weight, bucket capacity, boom and arm dimensions, hydraulic system configuration, pontoon dimensions and working range.
HK150SD is supplied at 15,000 kg with a 0.25 m³ standard bucket and hydraulic extendable undercarriage.
HK200SD is supplied at 20,000 kg with a 0.4 m³ standard bucket and manual or optional hydraulic extendable undercarriage.
HK300SD is supplied at 30,000 kg with a 0.8 m³ standard bucket and explicitly supplied applications covering river dredging, wetland construction, oil and gas pipeline projects, flood control and coastal engineering.
HK300SDA is supplied at 36,000 kg total weight with a 0.5 m³ standard bucket and a longer supplied digging reach than the other listed models, together with optional additional pontoon and spud configurations.
HK400SD is supplied at 40,000 kg with a 1.3 m³ standard bucket and higher-capacity engine and hydraulic system specifications than the smaller supplied models.
These differences are provided for technical evaluation only and do not constitute a ranking. Final model selection should be based on project requirements and the complete specification of the selected machine.
