Detailed information
-
Hydraulic torque wrench with ultra-precise spline gear and 9-drive pawls. Unlike the common two-pawl hydraulic torque wrenches from other manufacturers, which can get stuck and make it impossible to remove the wrench from the bolt due to "gear engagement that disrupts accuracy," the Plarado guarantees high torque accuracy of ±3% with fine incremental angles that allow ratchet operation even with minimal rotation. It can drive up to 4 gears per stroke. Additionally, unlike wrenches with a high load on the gears that can suffer from tooth chipping or wear, there is no load on the spline gear, ensuring a long lifespan.
-
Hydraulic torque wrench with a patented spherical bearing lever piston system. It has a structure that is resistant to impact, allowing the piston and lever block to automatically separate and reconnect, preventing damage. In contrast, hydraulic torque wrenches from other manufacturers have a pin-fixed piston rod, which is weak against twisting and impact, leading to significant failures.
-
High-pressure safety double cylinder of Prarado's patented structure. The hydraulic torque wrench's inner chamber, which operates under ultra-high pressure of 80MPa, is designed with a double structure for added safety in case of emergencies. Patented SQS safety double structure. It is the only safety feature in the industry!
-
Automatic safety relief valve In the event of a hose disconnection, a safety relief valve (relief valve) is built in that automatically operates when the specified hydraulic pressure exceeds the limit.
-
The Plarad hydraulic torque wrench comes standard with a safety handle on all models. It ensures safe operation and is convenient for transportation. (For models PL210SC and above)
-
Standard reaction force receiver included with the hydraulic wrench. One-touch reaction force receiver that rotates 360 degrees in 5-degree increments.
-
We also accept the production of special reaction supports tailored to the customer's bolt usage conditions.
-
PLARAD hydraulic torque wrench with a hexagonal integrated output shaft. Designed for tightening bolts with hexagonal holes. A hexagon socket can also be attached, but in cases with height restrictions, the hexagonal integrated output shaft, which can achieve a lower height, is effective.
-
Hydraulic torque wrench and torque meter GMV2 option. A special specification hydraulic torque wrench with a high-precision torque sensor (strain gauge) built into the output shaft allows for the measurement of actual tightening torque instead of hydraulic conversion values, enabling ultra-high precision torque management for bolt tightening. Torque meter GMV2: measures actual torque and saves tightening data.
