A helicopter manufacturer had a critical torque application during the routine maintenance process of their aircraft. The rotor of the helicopter requires servicing after every 20 hours of flight. Some of these aircraft are serviced in very remote locations, where air or power supply isn’t available or reliable. Ensuring proper torque control for the rotor assembly nut is a critical element for maintaining the continuous safe operation of the helicopter.
INITIAL SITUATION
The director of maintenance contacted a partner of alkitronic and explained the application requirements. He inquired about cost-effective torque control options to ensure their critical fastening application's quality and safety needs. The client could exclude impact, and hydraulic torque wrenches in the evaluation process for several reasons.
Impact wrenches lack torque control and is destructive by nature with their "ham-mering" design. These tools are not ergonomically friendly for a technician and require a high maintenance budget. Hydraulic wrenches are notorious for their heavy ratchets, bulky compressors and laborious operation. Hydraulic tools operate through a hydraulic ram that extends and retracts, ratcheting the head. Most importantly, they could not guarantee the power supply in both cases, with some locations being remote.
THE SOLUTION
The director of maintenance selected the alkitronic hand torque multiplier as the only option to resolve their critical maintenance application issue. The alkitronic hand torque multiplier provides precision tightening and loosening of all heavy-duty fastening connections. It is the ideal tool for applications where air and electricity aren't easily accessible. The gearing design of the hand torque multiplier allows for a high torque output with minimal input. alkitronic torque multipliers provide precision torque control, making it easier and safer to assemble or service fasteners while reducing application problems and tool costs.
TECHNICAL DATA OF THE HG SERIES
alkitronic M manual torque multiplier - for precise and energy-independent tightening and loosening of heavy-duty bolting connections.
Best working safety thanks to the precision locking mechanism.
The components of the alkitronic power gears are manufactured in a high-precision chipless process which ensures the highest possible operational demands upon the lowest wear.
The shearing pin built into the driveshaft protects against input overload.
