Tunnel Boring Machine (TBM) Main Drive System<\/h3>\n<p><strong>1. Propelling Cylinder<\/strong><br>\nProvide powerful forward thrust for the cutter head, overcome rock stratum resistance, control tunneling speed and straightness of the tunnel.<\/p>\n<p><strong>2. Gripper Cylinder<\/strong><br>\nPush the gripper shoes tightly against the tunnel wall to lock the whole machine, create reaction force for the propulsion system during excavation.<\/p>\n<p><strong>3. Steering &amp; Deviation Correction Cylinder<\/strong><br>\nAdjust the left-right and up-down posture of the main machine, correct tunneling deviation to ensure the tunnel follows the designed axis.<\/p>\n\n<h3>2. Cutting Head &amp; Rotary Mechanism<\/h3>\n<p><strong>1. Swing Cylinder for Cutter Head<\/strong><br>\nControl the horizontal and vertical swinging of the cutting arm, realize layered cutting of rock and soil.<\/p>\n<p><strong>2. Lifting Cylinder for Cutting Arm<\/strong><br>\nRaise and lower the cutting boom to adjust excavation height and adapt to different working faces.<\/p>\n\n<h3>3. Conveying &amp; Discharging System<\/h3>\n<p><strong>1. Conveyor Telescopic Cylinder<\/strong><br>\nExtend and retract the belt conveyor to transport muck out of the tunnel continuously.<\/p>\n<p><strong>2. Discharge Gate Cylinder<\/strong><br>\nOpen and close the slag outlet baffle to control the flow of excavated spoil.<\/p>\n\n<h3>4. Support, Dust Reduction and Auxiliary Devices<\/h3>\n<p><strong>1. Shield Support Cylinder<\/strong><br>\nSupport the tunnel surrounding rock temporarily to prevent collapse and ensure construction safety.<\/p>\n<p><strong>2. Sprinkler Arm Lifting Cylinder<\/strong><br>\nAdjust the angle of dust suppression spray pipes to reduce dust in the working area.<\/p>\n<p><strong>3. Foot Jack Leveling Cylinder<\/strong><br>\nLevel the whole equipment on uneven ground during startup and parking.<\/p>\n\n<h3>5. Roadheader (Coal Mine Underground Excavator) Special Cylinders<\/h3>\n<p>Boom lifting &amp; swinging cylinders, shovel plate pushing cylinders, crawler tension cylinders, rear support leg cylinders, hydraulic locking cylinders for the rotating platform.<\/p>\n\n<h3>Brief Product Description<\/h3>\n<p>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.<\/p>\n<\/div>\n<img src=\"https:\/\/zqhydrauliccylinder.com\/wp-content\/uploads\/2026\/08\/\u7ffb\u8bd1-1-2-scaled.png\">\n<img src=\"https:\/\/zqhydrauliccylinder.com\/wp-content\/uploads\/2026\/08\/\u7ffb\u8bd1-4-scaled.png\">","sort_order":2}]},"naibb2pr_product_category":[29],"naibb2pr_product_tag":[],"class_list":["post-421","naibb2pr_products","type-naibb2pr_products","status-publish","has-post-thumbnail","hentry","naibb2pr_product_category-mining-machinery-hydraulic-cylinders"],"acf":[],"_links":{"self":[{"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/naibb2pr_products\/421","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/naibb2pr_products"}],"about":[{"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/types\/naibb2pr_products"}],"version-history":[{"count":3,"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/naibb2pr_products\/421\/revisions"}],"predecessor-version":[{"id":432,"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/naibb2pr_products\/421\/revisions\/432"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/media\/426"}],"wp:attachment":[{"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/media?parent=421"}],"wp:term":[{"taxonomy":"naibb2pr_product_category","embeddable":true,"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/naibb2pr_product_category?post=421"},{"taxonomy":"naibb2pr_product_tag","embeddable":true,"href":"https:\/\/zqhydrauliccylinder.com\/fr\/wp-json\/wp\/v2\/naibb2pr_product_tag?post=421"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
