Construction Machinery Products
Usage: Key components used by machinery such as tunnel boring machines during tunneling operations.
Use: An important load-bearing component for freight cars.
Usage: The high-end hydraulic plowshare is the primary load-bearing component.
Purpose: To support the cutterhead ring, cushion external impacts, and ensure contact between the cutterhead ring and the excavation face; it is the main component of the shield machine’s cutterhead.
Purpose: Used to transmit traction, braking force, or connect mechanical systems, ensuring stable operation and efficient power transmission of locomotives.
Usage: The high-end hydraulic plowshare is the primary load-bearing component.
Usage: One of the “four wheels and one track” components of construction machinery chassis, responsible for guiding the direction of track movement and adjusting track tension, among other functions.
Usage: An essential component of electromagnetic chucks, primarily used to protect internal components and ensure their proper operation.
Application: One of the “four wheels and one belt” components of construction machinery chassis—a “heart” for power transmission in the construction machinery chassis system. Its primary functions include transmitting torque, driving the tracks, controlling steering, and bearing loads.
Top Drive Drilling Suspension Body
Application: In drilling top-drive systems, the substructure serves both as a load-bearing framework and as an integrated functional platform, directly impacting the top-drive’s operational efficiency, safety, and service life.
Medium Conveying Hemisphere Valve
Application: Control valves used in fluid media conveyance, widely applied in industries such as petroleum, chemical engineering, power generation, and metallurgy.
Application: In drilling top-drive systems, the substructure serves both as a load-bearing framework and as an integrated functional platform, directly impacting the top-drive’s operational efficiency, safety, and service life.
Application: An essential component of the lip-edge systems for large electric shovels, hydraulic shovels, and wheel loaders.
