Detailed information
-
Ultra-precise spline gear with 9 drive claws. Unlike hydraulic torque wrenches from other manufacturers that often have a two-claw drive system and can get stuck on bolts, there is no "gear engagement that disrupts accuracy!" In other products, tightening can only be completed at the angle position where the reverse stop functions, resulting in a large torque error compared to the set value. However, the Plarado guarantees high torque accuracy of ±3% with a fine feed angle that allows ratchet operation even with slight rotation. Maximum 4 gear drives per stroke. Additionally, there is no chipping or wear like 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 other manufacturers' hydraulic torque wrenches, the piston rod is pin-fixed, making it vulnerable to twisting and impact, which can lead to failures.
-
Hydraulic torque wrench with patented high-pressure safety double cylinder. The internal 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!
-
Hexagonal insert parts. Since the replacement parts use a spline gear mechanism, the ratchet can be replaced with just the insert, even with multiple approximate sizes.
-
Hydraulic torque wrench with automatic safety relief valve. In the event of a hydraulic hose disconnection, the built-in safety relief valve (relief valve) automatically activates if the specified hydraulic pressure exceeds the limit, ensuring safety.
-
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 included as standard with PL12VS and above. It is convenient for tightening work and transportation of hydraulic wrenches.
-
Even in bolt tightening work in confined 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. Detachable and can be manufactured to the required length.
