Recently, Caterpillar announced that the new Cat 336D2 XE/D2 L XE hybrid hydraulic excavator is on the market. It is the first machine in this category to increase fuel efficiency by up to 25%. For customers who want to have the power and productivity of a standard Cat 336D2 machine and want to significantly reduce their own and operational costs, the Cat 336D2 The XE/D2 L XE is undoubtedly the ideal choice.
New Cat® 336D2 XE/D2 L XE Hybrid Hydraulic Excavator
Cat 336D2 XE/D2 L XE utilizes three basic technologies for superior performance and fuel efficiency: Cat Electronic Standardized Programmable (ESP) smoothly transitions between hydraulic hybrid power sources, engines and accumulators To save fuel; the Cat Adaptive Control System Volve (ACS valve) optimizes performance by intelligently implementing limits and managing flow to control machine motion, which means operators have what they want Power and accuracy; the Cat Hydraulic Hybrid Swing System acquires the gyro braking energy of the excavator's superstructure and stores it in the accumulator, which is then reused during slewing acceleration – a simple A reliable and cost-effective solution that will help significantly reduce your cost per ton of operation.
The Cat 336D2 XE/D2 L XE is equipped with a 208-kW (278 hp) Cat C9 ACERTTM engine with automatic engine speed control for additional fuel savings for the Cat 336D2 XE/D2 L XE. In addition, this feature automatically reduces engine speed under no-load or light-load conditions, further reducing fuel consumption. Another cost-reducing method for the Cat 336D2 XE/D2 L XE hydraulic excavator is to operate in a fuel-saving mode with no digging and lifting capabilities. An efficient fuel filtration system protects the engine from inferior fuel, while the electric fuel pump eliminates filter pre-charge problems, thereby reducing the risk of fuel contamination. The C9 ACERTTM engine meets US EPA Tier 2, Euro II and China Tier 2 emissions standards. It uses proven, rugged components and sophisticated manufacturing processes to ensure reliable and efficient operation.
Efficient hydraulic system
Compared to the standard model, the Cat 336D2, the ESP pump used in the 336D2 XE has a larger displacement, allowing the new pump to produce the hydraulic flow and pressure of the Cat 336D2 at lower speeds. The patented ACS valve provides precise control and is a core component of the hydraulic system that optimizes pump output performance.
In addition, the Cat 336D2 XE/D2 L XE also uses a hydraulic oil regenerative valve in the boom lowering and stick retracting circuit to deliver hydraulic oil from the cylinder directly to the other side of the cylinder, thus reducing the main pump The amount of oil required saves fuel and reduces system heating. To increase operator comfort and reduce shock loads on the machine, a stroke end bumper is used on both the rod end of the boom cylinder and the end of the stick cylinder.
Advanced features, live up to expectations
The Cat 336D2 XE/D2 L XE features a low-effort joystick control in a flexible, adjustable console that displays 42 languages ​​to support today's diverse workforce, allowing each operator to focus In the ongoing work. It also displays images from the rear view surveillance camera, further enhancing job site safety and productivity. The well-designed cab provides the convenience of the driver's operation, such as pressurizing the cab with filtered air and all the glass sticking directly to the cab, eliminating the need for a window frame to expand the field of view for the operator Provides a spacious, quiet and comfortable environment.
The heavy-duty main structure ensures long-lasting durability of the Cat 336D2 XE/D2 L XE. The rugged main frame is designed for the most demanding applications. The X-shaped box section body has excellent resistance to twisting. Press-formed, robot-welded track roller frames provide excellent strength and durability. The track rollers, carrier rollers and guide wheels are sealed and lubricated for long life and extend the machine's working time on the job site.
The Cat 336D2 XE/D2 L XE offers a heavy-duty standard front linkage and is available with a choice of two standard sticks and two heavy-duty standard stick options. At the same time, the Cat 336D2 XE/D2 L XE also offers a large bucket of excavation front linkages and two arm options for demanding applications. Maximum excavation depths up to 8210 mm (26'11"). Choose from a wide range of Cat buckets and work tools to increase machine versatility, including connectors, pin grab connectors, E-Series hammers, rippers, Grabs, multi-function processors, hydraulic shears, shredders and compactors.
Maintenance and maintenance saves time and money
The design and layout of the Cat 336D2 XE/D2 L XE takes into account the needs of service technicians. Most service points are easily accessible from the ground, ensuring quick and efficient repair and maintenance tasks. The concentrated remote lubrication points on the boom deliver grease to inaccessible locations on the boom and stick. The engine radiator, hydraulic oil cooler, air-to-air aftercooler and air conditioning condenser can be easily accessed through the access door on the left rear side. The radiator is equipped with a water tank and a drain cock for maintenance from the ground. The anti-slide covers the entire superstructure and storage compartment to prevent maintenance personnel from slipping during maintenance. In addition, countersunk bolts are used to reduce the risk of tripping, further enhancing safety.
Cat Connect intelligently utilizes a variety of technologies and services to increase job site efficiency. Cat Connect offers LINK, GRADE, and DETECT technologies. LINK technology such as Product LinkTM can help you connect to your device wirelessly, giving you important information about the machine or fleet's working conditions. By tracking machine position, hours of operation, fuel usage, idle time and event codes via the real-time online VisionLink® interface, you can make timely decisions based on real-world conditions, increasing job site efficiency and productivity while reducing operating costs . GRADE technology such as the AccuGradeTM system provides 3D bucket tip position and height guidance through the in-cab display to accurately display the job location and the amount of cut or fill. AccuGradeTM reduces the need for manual grade stakes and inspections in traditional construction during trimming, reducing labor costs and increasing job site safety. DETECT technology, including rear-view cameras, expands the operator's field of view and makes them aware of the surrounding environment of the work equipment. As a result, they work more confidently, not only to maximize the efficiency of the machine, but also to ensure the safety of people and assets.
