Cylindres hydrauliques pour haveuse
Nous fournissons des vérins hydrauliques robustes pour haveuses destinés aux équipements de creusement de tunnels et d'exploitation minière souterraine. Largement utilisés sur les haveuses pour les projets de creusement de tunnels souterrains. Un tube de vérin à haute résistance, une tige de piston résistante à l'usure et des composants d'étanchéité étanches à la poussière garantissent des performances stables dans des conditions de travail souterraines difficiles, poussiéreuses et à forte charge. Une personnalisation OEM et ODM est disponible selon vos plans. Chaque vérin subit des tests de pression stricts avant la livraison.

Application Scope of TBM & Roadheader Hydraulic Cylinders
1. Tunnel Boring Machine (TBM) Main Drive System
1. Propelling Cylinder
Provide powerful forward thrust for the cutter head, overcome rock stratum resistance, control tunneling speed and straightness of the tunnel.
2. Gripper Cylinder
Push the gripper shoes tightly against the tunnel wall to lock the whole machine, create reaction force for the propulsion system during excavation.
3. Steering & Deviation Correction Cylinder
Adjust the left-right and up-down posture of the main machine, correct tunneling deviation to ensure the tunnel follows the designed axis.
2. Cutting Head & Rotary Mechanism
1. Swing Cylinder for Cutter Head
Control the horizontal and vertical swinging of the cutting arm, realize layered cutting of rock and soil.
2. Lifting Cylinder for Cutting Arm
Raise and lower the cutting boom to adjust excavation height and adapt to different working faces.
3. Conveying & Discharging System
1. Conveyor Telescopic Cylinder
Extend and retract the belt conveyor to transport muck out of the tunnel continuously.
2. Discharge Gate Cylinder
Open and close the slag outlet baffle to control the flow of excavated spoil.
4. Support, Dust Reduction and Auxiliary Devices
1. Shield Support Cylinder
Support the tunnel surrounding rock temporarily to prevent collapse and ensure construction safety.
2. Sprinkler Arm Lifting Cylinder
Adjust the angle of dust suppression spray pipes to reduce dust in the working area.
3. Foot Jack Leveling Cylinder
Level the whole equipment on uneven ground during startup and parking.
5. Roadheader (Coal Mine Underground Excavator) Special Cylinders
Boom lifting & swinging cylinders, shovel plate pushing cylinders, crawler tension cylinders, rear support leg cylinders, hydraulic locking cylinders for the rotating platform.
Brief Product Description
Hydraulic cylinders for tunneling machinery are core executive components of full-face tunnel boring machines (TBM) and coal mine roadheaders, widely used in propulsion, gripper locking, deviation correction, cutting arm movement, muck conveying, surrounding rock temporary support and equipment leveling in subway tunnels, mountain highway tunnels, water conservancy culverts and underground mine roadways.
