Special Excavators

• Common Types of Special Excavators

.Amphibious Excavator

Features: Equipped with pontoons or rubber tracks, it can operate in swamps and shallow water areas.

Application: river dredging, wetland construction, flood control and rescue.

.Long Arm Excavator

Features: The arm span can reach 20-30 meters (about 10 meters for ordinary excavators) and can be extended and retracted in multiple sections.

Application: deep pit excavation, high-rise building demolition, bridge construction.

.Demolition Excavator (building demolition machine)

Features: Reinforced cab to prevent rockfall, equipped with hydraulic shears or breaker hammer.

Application: building demolition, concrete structure crushing.

.Mini Excavator

Features: Weight less than 6 tons, width less than 1 meter, can enter narrow spaces.

Application: interior decoration, gardening, underground pipeline construction.

.Walking Excavator

Features: With hydraulic outriggers, it can climb slopes like a "spider" (slopes up to 45°).

Application: Emergency rescue in mountains, forests and rugged terrains.

.Electromagnetic Excavator

Features: An electromagnetic suction cup is installed at the end of the arm to absorb metal waste

Application: scrap steel recycling, garbage sorting.

• Core Technology Highlights

Customized attachments: Quick-change hydraulic connectors, compatible with drill bits, grabs, rammers, etc.

Intelligent control system: Some models are equipped with GPS positioning or remote control operation, suitable for hazardous environments.

Environmentally friendly design: Electric or hybrid models reduce noise and emissions (e.g. nighttime construction in cities).

• Application Scenario Comparison

Type                                              Typical scenarios                                                Advantages

Amphibious                         Desilting of mangrove forests           Does not damage wetland ecology,strong buoyancy

Walking                           Landslide rescue after earthquake                Stable movement in extreme terrain

Demolition type        Cleaning up the old power plant after blast       Highly efficient crushing of reinforced concrete

• Small but interesting special models

Remote control explosion-proof excavator: used at chemical plant explosion sites, anti-static design.

Subsea trencher: for laying deep sea cables, with its own pressurized cabin.

Polar excavator: -50℃ low temperature start-up, track anti-icing.

• Purchase suggestions

Terrain: Choose wide tracks or pontoon type for soft foundation; choose walking type for mountainous terrain.

Working depth: Deep pit operations require a long arm + extended stick.

Safety: Demolition operations require rollover cages and falling object protection.

Special excavators adapt to human engineering extreme scenarios through "transformation" and may develop towards greater intelligence (AI autonomous operation) and greenness (hydrogen energy) in the future.
