CAT 777 is a Caterpillar rigid dump truck designed for heavy-load mining transportation. It has superb load-bearing capacity, excellent off-road performance and high reliability. It is the main transportation equipment in open-pit mines, quarrying plants and large-scale infrastructure construction.
CAT 777 mining rigid dump truck has many significant advantages in mining operations and is one of the star models for open-pit mine transportation operations. The following are its core advantages in mining conditions:
1. Super strong load-bearing capacity
CAT 777 series are usually 100-ton mining trucks, which can transport a large amount of ore or stripping materials at a time, thus reducing the number of transportation times and improving overall production efficiency. Equipped with a unique Caterpillar engine and advanced transmission system, it can provide sufficient power and high travel speed even on steep slopes and bad road conditions, shortening the transportation cycle.
2. Excellent reliability and durability:
The CAT 777 is designed with high-strength steel and a rugged chassis to withstand the tremendous impact and pressure in mining operations, ensuring long-term reliability and durability.
3. Excellent power system
Equipped with a high-performance C32 ACERT engine, it is adaptable to high altitudes, high temperatures and harsh working conditions.
4. Energy saving and environmental protection
It is equipped with functions such as automatic idle control and engine braking to improve fuel efficiency and reduce emissions.
5. Strong driving comfort
The cab with shock absorption system, high-definition display screen and multiple driving assistance functions enhance the driver's operating experience.
CAT 777 mining dump truck has become one of the key equipment for mining companies to improve operational efficiency and reduce costs due to its high productivity, reliability, operability, safety and continuously advanced technology.
CAT 777 is often used in mining operations, and the rims used need to be able to effectively absorb impact loads and prevent deformation and cracking, so that CAT 777 is not prone to problems such as ring bursting or loosening during high-speed and heavy-load operation.
Because we specially developed and produced 19.50-49/4.0 5PC rims to match CAT 777.
The 19.50-49/4.0 rim is a large-size, five-piece mining rim specially designed for large mining vehicles and is widely used in harsh mining conditions.
19.50-49/4.0 has a super load-bearing capacity and is suitable for giant tires (such as 35/65R49, 36.00R49), which can withstand weights ranging from tens to hundreds of tons. It meets the safety requirements of mining rigid trucks and large loaders under high load and high-intensity operations.
The five-piece design is easy to maintain. There is no need to pry the tire when removing or installing the tire. The split structure greatly reduces the working hours and improves the efficiency of tire replacement. It is convenient to install common accessories in mining areas such as tire pressure monitoring system and inflation protection device.
The precise structural design can withstand the strong impact and lateral force from rugged mines and heavy operations. It is not easy to deform, loosen or burst, which improves the safety of the vehicle operation.
The rim surface is specially treated with electrophoresis and powder spraying to effectively prevent acidic and alkaline water and soil corrosion and adapt to the humid, saline and extreme climate environment in the mining area, making the CAT 777 perform better in mining operations!
What are the advantages of using 19.50-49/4.0 rims in mines?
The use of 19.50-49/4.0 rims in mining operations has the following obvious advantages, mainly reflected in safety, load-bearing capacity, adaptability and maintenance efficiency. It is very suitable for large rigid mining dump trucks such as CAT 777.
Five advantages of using 19.50-49/4.0 rims in mines:
1. Super strong carrying capacity to ensure efficient transportation
The 19.50-49/4.0 rim is designed to match giant tires such as 35/65R49 and 36.00R49, and can carry a vehicle weight of more than 100 tons to meet the long-term high-intensity transportation needs of mining areas. It is particularly suitable for heavy mining equipment to operate stably in complex terrains such as long slopes, soft soil, and gravel.
2. Five-piece structure, convenient and safe maintenance
The five-piece structure design can be quickly separated during the disassembly process, greatly simplifying the tire disassembly and assembly process, reducing the labor intensity of workers and the tire damage rate. At the same time, it effectively improves the vehicle maintenance efficiency and tire replacement turnover speed, reducing downtime.
3. High impact resistance and durability
The wheel rim is made of high-quality steel, with reinforced welds and impact-resistant structural design, which can withstand the stress caused by frequent vibrations, collisions and high-speed operation in the mining area. It is especially suitable for harsh conditions such as hard rock mines and open-pit coal mines, and the wheel rim is not easy to deform or crack.
4. Precisely adapted to giant mining tires
It is precisely matched with large-size tires of international mainstream brands such as Bridgestone, Michelin, Goodyear, Triangle, etc., which can improve the tire life and grip performance. It can effectively prevent hidden dangers such as tire slippage, air leakage or tire blowout, and improve the stability of vehicle operation.
5. Anti-corrosion coating, adaptable to extreme environment
The rims are usually treated with sandblasting + electrophoretic primer + polyester powder coating or heavy-duty anti-corrosion hot zinc spraying technology, which has excellent corrosion resistance, salt and alkali resistance, and moisture and heat resistance, ensuring long-term service in open-pit mines and rainy and snowy areas.
The 19.50-49/4.0 rim is a reliable "fulcrum" for large mining dump trucks and loaders operating in high-intensity mining areas. Its structural strength, safety performance and maintenance convenience ensure efficient and safe mining operations.
