Product Detailed Description

General Overview of CAT350 Large Crawler Excavator

CAT350 Hydraulic Excavator stands as a flagship heavy-duty mining crawler digger independently optimized by Caterpillar for global open-pit mining, quarry exploitation and large-scale infrastructure earthmoving works. As one core model of Caterpillar’s large digging machinery lineup, this Caterpillar 350 Digger balances powerful output performance and long-term operating economy, which makes it widely favored by mining contractors, quarry owners and large construction engineering companies from North America, Australia, Southeast Asia and Africa. When talking about large industrial earthmoving equipment, the CAT350 large crawler excavator always becomes the preferred option for medium and large open mine bulk ore excavation, stockyard material shifting and highway foundation digging tasks. Different from mid-size construction diggers, CAT350 targets heavy-load continuous working scenarios, with core configurations customized for high-abrasion rocky and dusty working sites, fully complying with international EPA emission standards to satisfy strict environmental access rules of most developed countries’ construction industries. Over decades of market verification, Caterpillar upgrades core hydraulic and power parts of CAT350 continuously, helping end users lower comprehensive use cost while lifting daily loading capacity of the whole machine, and this is the core reason why numerous global bulk mining clients repeatedly place repeat orders on this CAT heavy duty earthmoving machine.

Core Product Features & Unique Technical Strength

As mature large mining equipment, CAT350 Hydraulic Excavator owns three core competitive advantages covering power, hydraulic system and structural durability, far exceeding many same-level generic brand large diggers on the global machinery market.

Original CAT C13 Diesel Power Engine

Equipped with genuine Caterpillar C13 turbocharged diesel engine, this Caterpillar 350 Digger meets EU Stage V & US EPA Tier4 final emission requirement, realizing stable power output even under ultra-low temperature high-altitude mining conditions. The optimized fuel injection system controls incomplete combustion rate effectively, cutting unit ore loading fuel consumption compared with old-generation CAT large crawler excavator models, and the engine’s self-protection shutdown function avoids damage caused by overheating or lack of lubricating oil during nonstop 24-hour site operation.

Upgraded Load-Sensing Hydraulic Control System

The customized load-sensing hydraulic system of CAT350 mining equipment automatically adjusts oil flow based on digging resistance, reducing invalid power loss in boom, arm and bucket action process. Built-in independent hydraulic oil cooling loop keeps hydraulic oil temperature steady under long-time continuous heavy digging, preventing hydraulic pipeline aging and seal leakage caused by overheat, which greatly lengthens the overhaul cycle of the whole hydraulic system for end users’ daily bulk earthmoving work.

Reinforced High Abrasion Resistant Working Device

Boom, stick and standard digging bucket of CAT heavy duty earthmoving machine adopt high-strength wear-resistant alloy steel, with thickened welding position at stress concentration areas such as bucket root and boom hinge. The standard bucket’s wear plate can be quickly replaced without whole component disassembly, lowering later maintenance spare parts cost for mine site operators, especially suitable for high-abrasion granite, limestone and iron ore mining excavation scenarios.

Diversified Application Scenarios for CAT350 Large Crawler Excavator

Thanks to balanced performance between digging force and site mobility, CAT350 Hydraulic Excavator can be deployed across multiple heavy-industry fields globally, covering four core application categories below:
  1. Open-pit Mine Exploitation: Mainly used for bulk iron ore, limestone, coal mine stripping, ore stockpiling and truck loading work; Picture caption: CAT350 Hydraulic Excavator Working At Open Pit Quarry Site

  2. Large Infrastructure Construction: Highway & railway foundation earthwork, reservoir channel excavation, airport ground leveling and large port yard backfilling; Picture caption: Caterpillar 350 Digger For Large Construction Earthmoving Project

  3. Quarry & Aggregate Processing: Rocky mountain blasting residue cleanup, stone raw material excavation for aggregate processing plants; Picture caption: CAT Large Crawler Excavator In Stone Quarry Working Condition

  4. Scrap & Heavy Waste Recycling: Large construction waste stacking, scrap steel yard bulk material handling for industrial recycling factories.

Global Customer Cases & Real Buyer Feedback

We have accumulated hundreds of real cooperative cases of CAT350 large crawler excavator with global mining enterprises, pick two typical representative buyer cases as below with authentic client feedback:

Australia Local Quarry Contractor Cooperation Case

In 2024, one large limestone quarry company from Queensland Australia purchased 3 units of our CAT350 Hydraulic Excavator for open-pit stone mining and loading work. After six months of continuous site operation, their project manager left feedback: “These Caterpillar 350 Digger machines we bought from Jinan Tuiwa run steadily in our high-dust rocky quarry, fuel consumption is lower than our previous old-brand large diggers, after-sales spare parts supply from Tuiwa is efficient, we plan to add another two units in next quarter for our new mine expansion project.”

South Africa Open Coal Mine Purchasing Case

A South Africa coal mining enterprise ordered two sets of CAT heavy duty earthmoving machine CAT350 in early 2025 for coal stripping work at their open coal pit. Client feedback content: “Tuiwa’s pre-shipment full inspection saved us lots of post-purchase troubleshooting cost, CAT350’s hydraulic system performs well under our 22-hour daily continuous heavy load work, local after-sales technical guidance service responds within 48 hours when we need support.”
