Hydraulic cylinders play a crucial role in tunnel boring machines (TBM) and hard rock drilling machines, controlling various movements and operations of these specialized equipment. In tunnel boring, hydraulic cylinders drive the rotation and advancement of the boring head, coordinating with the propulsion system to ensure smooth forward movement. In hard rock drilling, they control the rotation, feed, and mixture and transport of rock fragments for the drilling bit. These cylinders not only need to be reliable and durable but also high-performance to tackle the challenges of underground projects, ensuring efficient tunnel excavation and rock drilling.
In excavators, hydraulic cylinders and pneumatic cylinders play crucial roles. Hydraulic cylinders are used to control the movement of the excavator's arm, boom, and bucket, enabling earthmoving and excavation operations. They provide precise control and power to adapt to different digging depths and angles. Pneumatic cylinders are employed to control the movement of the cabin, mudguards, protective covers, doors, and windows, providing operators with better visibility and comfort while ensuring the excavator's safety and protection. These components are essential for enhancing the operational efficiency, accuracy, and operator comfort of excavators, holding significant importance in civil engineering and construction fields.
In road rollers, hydraulic cylinders and pneumatic cylinders play a crucial role. Hydraulic cylinders are used to control the vibration system, adjust the position and angle of the drum, ensuring uniform compaction of roads and surfaces. Pneumatic cylinders, on the other hand, control the cabin, anti-skid systems, and protective covers, enhancing operator comfort and equipment safety. These components are essential for improving the quality, safety, and operational efficiency of roads and surfaces, providing critical support for road construction and maintenance work.
In concrete pumping equipment, hydraulic cylinders and pneumatic cylinders play a crucial role. Hydraulic cylinders are used to control the lifting, extension, rotation of the pumping device, and bending of the delivery pipes, adapting to different construction sites and concrete pouring requirements. They are also involved in operating valves in the hydraulic system to ensure the uniform delivery and pressure casting of concrete. Pneumatic cylinders control the elevation and position of the cabin, operation of system valves, as well as the equipment's lifting and maintenance operations. These components are vital for improving the operational efficiency, uniformity, safety, and operator comfort of concrete pumping equipment, contributing to the success of construction projects and ensuring high-quality concrete pouring.
In bulldozers, hydraulic cylinders and pneumatic cylinders play a crucial role. Hydraulic cylinders are used to control the bulldozer blade, ripper, and scrubbing system, adjusting the working angle, depth, and cleanliness. They provide precise control and power to adapt to the requirements of different earthmoving projects. Pneumatic cylinders are used to adjust the cabin, bottom legs, and other components, providing better visibility, stability, and operator comfort. These components are essential for improving the operational efficiency, earthmoving project quality, and safety of bulldozers, contributing to the enhancement of construction quality and efficiency in civil engineering and construction fields.
In milling machines, hydraulic cylinders and pneumatic cylinders play a crucial role. Hydraulic cylinders are used to control the lifting, tilting, and rotating movements of the milling head, as well as the forward and backward motion, adjusting the milling depth and angle, and the height and tension of the conveyor belt. They provide precise control and power to adapt to different road and pavement milling requirements. Pneumatic cylinders are used to adjust the cabin, anti-slip systems, and scrubbing systems, providing better visibility, stability, and operator comfort. These components are essential for improving the operational efficiency, construction quality, and safety of milling machines, contributing to the enhancement of road and pavement quality and safety.
