LOVOL FR170E Crawler Excavator

1.Performance

Strong power, faster response, smoother and more precise compound movements.

●High power engine

●Electronically controlled positive flow control system

During the design phase, Lovol combines technical knowledge in each field and is committed to developing a consistent and optimized overall system. The variables of the main pump and the action of the main valve spool are synchronized, so the positive flow system has better operational sensitivity. The fastest and smoothest action to achieve optimal working power.

●Original energy-saving system

For the first time, an independent cooling circuit system is used to provide stable hydraulic oil for the entire machine, so that the entire hydraulic system can always operate in a stable environment, improving the reliability of the hydraulic circuit system.

Variable back pressure technology is also used on the independent cooling circuit, which greatly reduces return oil pressure loss.

The fuel consumption of the entire system is reduced by 9% compared with before.

●Super high adaptability

Adapt to different operating conditions in the temperature range of -40°C ~ 50°C;

Adapt to plateau working conditions at 3000m altitude;

Adapt to high dust and harsh working conditions;

Cooperate with the crushing device to meet the crushing operations of hard materials such as granite;

The ultimate climbing angle is 35°.

2.Reliable

The continuously strengthened working device and chassis structure make the product more durable and durable.

use.

●Key structural parts

Continuously optimized design, stress testing, welding process and plate research to comprehensively improve the life of key structural parts;

The boom adopts a box-shaped structure, high-strength steel plate, and cooperates with robot welding technology to more than double the service life under mining conditions.

●Enhanced work equipment

The hinged part of the boom is integrally cast;

Copper-based graphite self-lubricating bushing;

High-strength rock bucket teeth.

High-strength wear-resistant material

The new large-capacity rock bucket uses high-strength and wear-resistant materials to increase strength and wear resistance by 40%.

●Core components

Relying on the R&D system of Lovol’s Japan I Process Center, we have established solid partnerships with internationally renowned companies, continuously optimizing and improving the quality and life of parts, and giving priority to engines, pumps, valves, motors, cylinders, controllers, etc.

●Sturdy and durable chassis structure

Improve the heat treatment standards for the contact surfaces between the four wheels and the tracks to double the wear resistance of the components;

The supporting wheels and guide wheels use extremely cold type lubricating oil and seals to ensure normal operation at an ambient temperature of -40°C;

Track track with lifelong self-lubricating and sealed chain rails;

Reinforced left and right track beams;

Powerful drive mechanism.

3. Efficiency

Higher productivity, lower overall operating costs.

●Excellent performance makes loading more efficient

The high-power engine and high-performance hydraulic system make the loading operation capability more outstanding, and the workload per unit time increases by 15%.

●Super digging power

On the basis of ensuring static excavation force, we are committed to the research and development of dynamic excavation force. When encountering large resistance during excavation, the system will automatically detect the pressure and automatically adjust the output pressure to ensure strong excavation during the dynamic excavation process. Effect.

●Efficiency improvement under heavy load conditions

Under heavy load conditions, the main controller will automatically adjust the power and speed according to changes in load to ensure high output power under heavy load conditions, thus improving the efficiency of the entire machine under heavy load conditions.

●Higher work efficiency

Due to the adoption of the latest technology and hydraulic system, the operating efficiency of the product is 3% higher than that of the previous generation product on the basis of the same fuel consumption.
