Detailed information

Hydraulic torque wrench with ultra-precision spline gear and 9-drive claws. Unlike the common 2-claw drive hydraulic torque wrenches from other manufacturers, which often get stuck on bolts due to "gear engagement that disrupts accuracy," our product does not have this issue! Other brands can only finish tightening at the angle position where the reverse stop engages, resulting in a large torque error compared to the set value. However, Plarado guarantees high torque accuracy of ±3% with a fine feed angle that allows ratchet operation even with slight rotation. It features a maximum of 4 gear drives per stroke. Additionally, unlike wrenches with a reverse stop mechanism that puts a heavy load on the gears, there is no chipping or wear, and the load on the spline gear is minimal, ensuring a long lifespan.
-
Hydraulic torque wrench with a patented spherical bearing lever piston system. It is designed to be 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 safety in case of emergencies. Patented SQS safety double structure. The only safety 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 Plarado 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. While a hexagon socket can also be attached, the hexagonal integrated output shaft is effective in situations where there are height restrictions, as it allows for a lower height.
-
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 can measure the actual tightening torque instead of hydraulic equivalent values, allowing for ultra-high precision torque management during bolt tightening. Torque meter GMV2: measures actual torque and saves tightening data.
