HW-150 extra-large hydraulic excavator: the steel beast that changed mining productivity

Jul 11, 2025

Amidst the din of open pit mines, Everwang Heavy Industry's HW-150 crawler excavator with its massive 150-ton body and precise and strong performance becomes an effective solution trusted by global mining giants. Built for extreme working conditions, this construction machine is a profound fusion of advanced technology and industrial strength, redefining the boundaries of heavy earthmoving equipment performance.

I. Key Features: Born for billions of tons of ore

is equipped with a low-speed, turbocharged, high-torque engine with a maximum power output of 630 kW, which keeps its power without deterioration on plateaus 4,000 meters above sea level. The electronically controlled intelligent injection system reduces fuel consumption by 18%, saving 500,000 yuan per year on fuel (based on 20 hours of daily operation).

Hydraulic revolution system

with two pumps independent flow distribution technology to achieve zero interference in compound action, lifting arm at the same time turning error rate <3%. Standard automatic hydraulic oil filtration device extends oil life up to 6,000 hours, and reduces maintenance cost by 40%.

Structural innovation: durability to withstand extreme working conditions

Mountain-class reinforced skeleton

Key structural parts utilize four-layer welding of composite steel plates, and a chromium-molybdenum alloy overlay is added in the stress concentration area, increasing torsional strength to 980 MPa (22% higher than the industry standard).

Ultra-stable undercarriage system

1.35m wide track plate + cross roller bearing steering mechanism, side tilt angle <1.8° at 35° gradient, overcoming the terrain limitations of traditional mining excavators.

Intelligent control: the mine commander in the digital age

3D operation control system

10-inch touch screen displaying real-time excavator position, load curve and fuel consumption data, automatic generation of daily operation report, precise optimization of loading cycle time up to 32 seconds per truck (with 100-ton trucks).

Panoramic safety system

360° all-round camera + millimeter wave radar with double protection, automatic obstacle warning within 20 meters. The cab is ISO 3471 certified for explosion safety, withstanding a 2 kg TNT equivalent shock wave.
