2018 Year Used 50 Ton Mining Large Crawler Excavator Of Cat349D

CAT 349D Excavator Engineering Machinery Equipment

CAT 349D hydraulic excavator is a product with excellent performance, excellent maneuverability, powerful digging force of dipper stick and bucket. This large mining equipment has outstanding lifting capacity. The manufacturer has simplified the maintenance items of the machine to adapt to the working environment of the mine, and it has a comfortable operating platform. These can not only improve productivity but also reduce customers' operating costs.

According to the official website of Caterpillar, the CAT 349D excavator is equipped with a CAT C13 engine with ACERT technology, which can provide 283 kW of horsepower. (Note: ACERT technology is a unique technology to reduce combustion point emissions.) In terms of the fuel system, the electronic control device used in the Cat C13 engine is used to control the mechanically driven unit fuel injection (MEUI) system. MEUI can provide the necessary high pressure, thereby achieving excellent fuel economy for users through fine fuel automation and relatively complete combustion.

In terms of the hydraulic system, the pilot pump of the second-hand CAT 349D crawler excavator is separated from each main pump to control the front linkage, rotation and travel operations. The operation of the pilot control valve is proportional to the movement of the joystick, achieving excellent controllability.

The main pump, control valve and hydraulic oil tank of the second-hand CAT 349D equipment are as close to each other as possible, and the reasonable location provides the highest level of system efficiency. And this design makes the lines and pipes between components shorter, which reduces friction loss and pressure drop.
The CAT 349D excavator has a hydraulically operated boom regeneration circuit, which can save energy during the boom retraction process and improve multi-functional performance. The boom regeneration circuit of the 50-ton CAT 349D excavator is electronically operated and managed by the machine's ECM (engine control board). This system improves cycle time and fuel efficiency, thereby increasing productivity and reducing operating costs.
The operator station of the second-hand CAT 349D construction machine is spacious, quiet and comfortable to ensure the operator's labor efficiency. Switches, dials and controls are all within the operator's reach. The design of the monitor is easy to observe and helps to maximize the field of vision.

The standard air suspension seat of the mining equipment CAT 349D excavator can be adjusted to suit the operator's body shape and weight. It is worth mentioning that this product has a pressurized cab that provides forced filtered ventilation and can choose fresh or recirculated air. In terms of vision, all glass in the cab, except the rear window, has no window frame, which can maximize the field of vision. The large polycarbonate plastic skylight also provides the operator with excellent upward vision.

The exterior of the used CAT 349D cab features thick steel tubes along the bottom edge of the cab, which improves fatigue resistance and vibration reduction. In addition, this design allows the anti-falling object protection structure to be bolted directly to the cab, which can be installed before leaving the factory or as an accessory to enable the machine to meet the technical parameters and work site requirements.

CAT 349D crawler section

The idler guard and bolt-on center guard of the CAT 349D are standard equipment. They help keep the tracks aligned when driving or working on slopes. Optional guards are available for applications that require additional track protection or alignment.

In addition, the CAT 349D can be equipped with a positive pin fixed 2 (PPR2) type track and cast idler. PPR2 prevents track pins from falling off the track links, while cast idlers provide longer life. Both options are ideal for extreme applications or those requiring long travel distances.
CAT 349D Buckets

A wide range of work tools for used CAT 349D excavators, including buckets, hammers, grapples, shears, multi-processors and rippers. Each tool is specifically designed to optimize the performance of the machine. By loading different tools, the CAT 349D can be adapted to work in a variety of applications such as mining, site and structure demolition, debris clearing, truck loading, waste handling, breaking up roads and bedrock, etc.
