Detailed information
-
Ultra-precision spline gear with 9 driving claws. Unlike hydraulic torque wrenches from other manufacturers that often have a two-claw drive system, which can become stuck and unable to be removed from bolts due to "gear engagement that disrupts precision," the Plarado guarantees high torque accuracy of ±3% with a fine feed angle that allows ratchet operation even with slight rotation. It can drive up to 4 gears per stroke. Additionally, there is no chipping or wear like that found in wrenches with a high load reverse stop mechanism, and since there is no load on the spline gear, it has a long lifespan.
-
Hydraulic torque wrench with a patented spherical bearing lever piston system. It features a structure that is resistant to impact, allowing the piston and lever block to automatically separate and reconnect, preventing damage. In contrast, other manufacturers' hydraulic torque wrenches have a pin-fixed piston rod, which is weak against twisting and impact, leading to potential failures.
-
Hydraulic torque wrench with a patented high-pressure safety double cylinder. The inner chamber of the hydraulic torque wrench, which operates under ultra-high pressure of 80MPa, is designed with a double structure for safety in case of emergencies. Patented SQS safety double structure. The only safety in the industry!
-
Patented hex insert exchange structure. Due to the spline gear mechanism for replacement parts, the insert can be exchanged without needing to replace the ratchet, even with multiple approximate sizes.
-
Hydraulic torque wrench with automatic safety relief valve. In the unlikely event of a hydraulic hose disconnection, the built-in safety relief valve (relief valve) automatically activates when the specified hydraulic pressure is exceeded, ensuring peace of mind.
-
Hydraulic torque wrench HSX ratchet exchange structure. The ratchet can be easily exchanged with other opposite side sizes. Made of lightweight duralumin alloy.
-
Safety handle for hydraulic wrenches. It is standard equipment for PL12VS and above. It is convenient for tightening operations and transportation of hydraulic wrenches.
-
Even in bolt tightening work in narrow spaces with height restrictions, it excels due to its slim design. PLARAD Hydraulic Torque Wrench Center Hole Type.
-
Extension Reaction Receiver for Hydraulic Torque Wrench. Equipped with the extension reaction receiver, it can accommodate bolt tightening with long bolt pitch. It is detachable, and we can manufacture it to the required length.
