The PW45 wheeled excavator is a remarkable piece of machinery that plays a crucial role in various construction projects.

1. Introduction：The PW45 wheeled excavator is designed to offer high – performance capabilities with its well – engineered components. It combines power, precision, and versatility, making it an ideal choice for construction, excavation, and material handling tasks.

1. Machine Specifications

Basic Parameters：With a total weight of 4000KG, the excavator is robust yet manageable. Its shipping length of 4530mm, total height during transportation of 2750mm, and transport width of 1600mm make it relatively easy to transport between job sites.

The tire center distance of 2210mm and counterweight ground clearance of 883mm ensure stability during operation. It has 8 – 650 tires, a boom length of 2400mm, and a stick length of 1200mm, which contribute to its efficient digging and lifting capabilities.

Working Range：The excavator’s maximum digging height of 3840mm, maximum dumping height of 3050mm, maximum digging depth of 2100mm, and maximum digging radius of 4300mm make it suitable for a wide range of excavation tasks. The minimum radius of gyration of 1250mm and maximum lifting upper/lower limits of 400/300 enhance its maneuverability and lifting capacity.

Dynamic System：Powered by an LD490 engine with a rated power of 34KW, the excavator is equipped with an efficient cooling method of inline four – cylinder water – cooled direct spray. This ensures that the engine operates at optimal temperatures even during long – term, heavy – duty operations.

Hydraulic System：The hydraulic system operates at a rated working pressure of 22mpa. It includes essential components such as a rotary motor, main pump, and variable plunger, which work together to provide smooth and precise control over the excavator’s movements.

Performance Parameters：With a bucket capacity (SAE) of 0.26m³ and a maximum digging force of 55.6KN, the PW45 can handle significant amounts of material. Its travel speed of 2.2KM/h and unit swing speed of 9 – 11r/min allow for efficient movement around the construction site. Additionally, the hydraulic oil capacity of 75L and hydraulic tank capacity of 60L ensure that the hydraulic system has sufficient fluid for continuous operation.

III. Conclusion：In conclusion, the PW45 wheeled excavator is a versatile and powerful machine that offers a combination of strength, precision, and efficiency. Its specifications make it a valuable asset in the construction industry, capable of handling a wide range of tasks with ease. Whether it’s digging foundations, handling materials, or performing other construction – related activities, the PW45 is a reliable choice for construction professionals.
