RoyalCorp Excavator , Powerful Shovel & Fast Transport, Less Pollution after Exhaust Purification for Two Times - details see: https://www.machineto.com/undergroud-excavator-powerful-shovel-less-pollution-after-underground-scraper-10106755

RoyalCorp underground excavator are widely used in the mining, water conservancy, railway, highway and tunnels projects, especially for the narrow, low cross (such as 2.0*2.0m) and muddy ones.

Advantages: solid and durable, high efficiency and simplicity of operation. When operating, only one driver can efficiently finish overall process including shovel, transport and unload. Besides, the advantages of low noise and exhaust emission are helpful to the environmental protection and drivers’ health.

Performance Features

Comfortable Driving & Easy Operation

Spacious and comfortable bridge with wide view and traverse seats are beneficial to the drivers’ observation. Proceed or step back freely, forward and backward both two times. Convenient power shift and flexible electronic controlled hydraulic steering can greatly reduce the labor intensity of drivers.

Powerful Shovel & Fast Transport

Driving system adopts hydrodynamic transmission with CVT to transfer power, which is introduced from Germany technology produced by the worldwide well-known military enterprise. Its features are as follows: good adaptability, strong traction, great work capacity, fast shovel and transport.

High Strength & Long Service Life

Front and rear frames with super heavy design are box structures-- heavy-gauge sheeting and high strength. The pin shaft sleeve is sealing structure-- dustproof, improving the lifespan.

Strong Driving Force, Environmental Protection & High Bucket Coefficient

Advantages of high-performance diesel engine: easy to start, low oil consumption & emission, high reliability, strong impetus; Bucket bottom lengthened and shape type of bucket do good to cutting and receiving more.

Less Pollution after Exhaust Purification for Two Times

Exhaust from diesel engine converts CO,HC and aldehydes to CO2 and water through the oxidation catalytic converter and then into the washing tank to purify again in order to make diesel exhaust particles (DEP), soot and SO2 get to a minimum, efficiently guaranteeing the operators’ health.

Reliable Oil Cylinder & Good Durability

Oil cylinder is produced by professional manufactures, its block and the piston rod with high precision machining and corresponding heat treatment. Imported parts are applied to oil seal, quality guaranteed.
