Product Details
Engine Block (Weichai WP10G220E343)
- Model: A 6-cylinder, 4-stroke, turbocharged and intercooled diesel engine from the Weichai WP10G series, serving as the "heart" of the loader.
- Power Parameters: Rated power of 162 kW at 2000 rpm, with strong maximum torque output to meet the needs of heavy-duty conditions such as loading and climbing.
- Structural Features: Individual cylinder head design combined with a frame-type main bearing structure, offering high strength and ease of maintenance. The Weichai logo is clearly visible on the cylinder block.
Exhaust and Intake System
- Exhaust Manifold: A cast-iron exhaust manifold that collects exhaust gases from each cylinder. Its segmented design reduces the risk of thermal stress cracking.
- Turbocharger: Located at the end of the manifold, it boosts power output by compressing intake air, and is a key component of the machine's strong performance.
- Muffler: The black cylindrical component above the engine, used to reduce exhaust noise while providing initial emissions control.
Heavy-Duty Lift Arm and Hydraulic Cylinder
The CAT SEM 655D 5T wheel loader features a reinforced box-section lift arm designed to withstand demanding loading conditions. The large-diameter lift cylinder provides strong lifting force for handling aggregate, sand, soil, and other bulk materials.
Key pivot points are equipped with heavy-duty pins and reinforced mounting brackets to improve durability under continuous high-load operation. Hydraulic hoses are securely routed and protected along the lift arm structure, reducing the risk of damage in harsh working environments.
The open lift arm design also provides good visibility of the bucket, helping operators position loads more accurately during truck loading, stockpiling, and material handling operations.
Heavy-Duty Articulated Steering System
The SEM 655D features a heavy-duty articulated frame with reinforced center hinge pins and hydraulic steering cylinders. This design provides a tight turning radius, excellent maneuverability, and reliable performance in confined job sites. The oscillating center joint helps maintain wheel contact on uneven terrain, improving machine stability and traction.
Products Application
The SEM655D wheel loader is a versatile all-rounder capable of handling a wide range of tasks. Specifically:
1. Mines and Quarries
These environments involve heavy-duty work and hard rock that standard machines often can't withstand. With its high power, this loader is built tough to handle tasks like scooping crushed stone, loading trucks, and site clearing.
2. Ports and Docks
Ports handle a diverse mix of bulk materials-sand, gravel, coal, and more. This loader offers fast loading and unloading capabilities, efficiently managing the entire workflow from ship unloading to material stockpiling and truck loading.
3. Aggregate Plants and Concrete Batching Plants
Feeding hoppers and stockpiling sand and gravel are routine tasks for this machine. It features an adjustable bucket capacity ranging from 2.7 to 4.5 cubic meters, ensuring high productivity with every scoop.
4. Coal Yards and Thermal Power Plants
Stacking coal and feeding hoppers require speed and fuel efficiency-two areas where this loader excels.
5. Tunneling Projects
A specialized side-dump version is available; it offers a tight turning radius and high maneuverability within tunnels, making it ideal for muck removal. This model has been used in challenging projects like the Sichuan-Tibet Railway tunnels.
6. Steel Mills and Infrastructure
Whether it's handling steel slag in mills, moving earth at construction sites, or working on road and airport construction, this loader is up to the task.
