List of spare parts

As the core executive component of excavators, hydraulic cylinders have developed various types according to different structural designs and work requirements, each with its unique performance characteristics and applicable scenarios. Understanding these different types of hydraulic cylinders and their characteristics is of great significance for the design, selection, operation, use, and maintenance of excavators. From simple single-stage hydraulic cylinders to complex multi-stage telescopic cylinders, from standard piston cylinders to special booster cylinders, the diversity of hydraulic technology provides flexible solutions for excavators to cope with various working conditions.

The most basic classification of hydraulic cylinders is based on their mode of action, mainly divided into two categories: single acting cylinders and double acting cylinders. The single acting oil cylinder only allows pressure oil to pass through one side of the piston, and the return stroke relies on gravity, spring force, or other external forces. The structure is simple but the function is limited. In excavators, single acting hydraulic cylinders are less commonly used and are mainly used for auxiliary functions or special devices. In contrast, the double acting oil cylinder can be filled with pressure oil on both sides of the piston, enabling bidirectional active control, precise action, and controllable output, making it the mainstream configuration of excavator working equipment.

Double acting oil cylinders can be further divided into single piston rod type and double piston rod type. The single piston rod cylinder (i.e. the piston has a rod on only one side) is the most commonly used form of excavator, characterized by unequal effective areas of the two chambers, resulting in asymmetric speed and output during extension and retraction 816. This asymmetry needs special consideration in excavator action planning, but it also provides more flexibility for system design. Double piston rod oil cylinder (with rods on both sides of the piston) has equal effective areas in both chambers, which can achieve symmetrical speed and output characteristics. However, its structure is relatively complex and it is less commonly used in excavators. It is mainly used in special occasions that require strict symmetrical movements.
