Electrical torque multipliers

Electrical torque multipliers with all-weather qualities

Electrical alkitronic® shut-off torque multipliers, ideal for extreme operating conditions in wind energy.

In the case of a large number of bolting processes, high speeds require a rapid working pace with high precision. Particularly in turbo-assembly applications, the devices show what they are made of. Unlike hydraulic wrenches, this eliminates the ratcheting "backward movement", which re-sults in enormous savings in work time. Other advantages of continuous turning are higher precision due to the pre-cise achievement of torque, more reliable technology and low running costs. This is why the alkitronic® torque mul-tipliers keep performing reliably, even in spite of wind, weather and other environmental influences. Almost all models are available with protection class IP54 (protection against moisture and dust) and can therefore also be used in the rain and in the offshore area. From 100 Nm to 42,500 Nm, there is no faster and more precise bolting technology.

Your advantages:

• Intelligent motor control guarantees precise achievement of the torque and high assembly speed• Repeat disengaging torque accuracy ± 2%• Higher service life due to low-wear and brushless motor • The IP54 models are protected against dust and rain• The devices can be used in all international power grids (100 to 253 V / 45 to 66 Hz) with constant torque accuracy• Modular software solutions for custom applications (e.g. torque/angle bollting method)• Bluetooth interface for communication and documentation of bolting processes (with alkitronic® App)

Almost all torque multipliers are also available in an angular version. The low height is specially designed for confined spaces. The alkitronic® EA is a battery-powered torque multiplier with high mobility, always ready to use and independent of external drive energy. The alkitronic® EF torque multiplier is also available with integrated LC display and torque/rotation angle method. The alkitronic® E is a robust, indestructible 2-speed torque multiplier.

Torque/angle bolting method: Highly precise and indispensable

This method is used in applications that need a higher bolting quality and require minimal friction: For example, when assembling or servicing rotor blade connections on the hub. Investigations showed that over 80% of the tightening torque is necessary to overcome the friction under the head and in the thread. In the torque/angle bolting method the friction coefficient in the thread and the bolt support no longer has an influence on the assembly preload force to be achieved. If you want to exclude disturbances, you can rest assured with the models EFCip/ECWip. As a quality supplier, alkitronic® is always the right partner for other bolting methods.

Hydraulic torque wrenches

In special industrial applications or due to technical requirements, hydraulic wrenches are often the only possible alternative to handle bolted connections. For example, in very cramped, hard to access bolting processes. Here, large tightening torques can be applied even in a small space.

As a rule of thumb, the following is applicable to alkitronic® hydraulic torque wrenches: A torque of about 1,000 Nm can be applied to the bolted connection per kg of torque wrench weight (operating pressure 700 bar). However, a hydraulic torque wrench works relatively slowly, but very precisely with ± 3 % accuracy. For a faster, reliable operation, we recommend our alkitronic® VELOX and NOVA hydraulic pumps.

Hydraulic torque wrench AX

alkitronic® Hydraulic torque wrench AX and AT

Very suitable if heavy bolted connections with large threads must be tightened in tight spaces with high forces. Even though they can not turn so quickly due to the “ratcheting”.

Hydraulic wrenches are ideal for use in explosive areas. Or in wind turbines e.g. in the flange connection in the interior of the towers; during assembly or maintenance of rotor blade connections on the hub as well as when bolting the azimuth brakes.

Fast alkitronic® hydraulic pumps additionally speed up the bolting processes and save time and money.

Hydraulic torque wrenches

alkitronic® Norwolf X Driver System with A-Drive and V-Drive

V-Drive and X-Driver combination

rable tools, the DMA does not have to be dismantled to displace it. Unique and highly flexible in its application. Can be adapted in all directions

The following is applicable for the alkitronic® Norwolf Hy-draulic X Driver System:An operating pressure of 100 - 700 bar is a prerequisite for the exact reproducibility of the specified torque ranges.

alkitronic® Norwolf V-drive

alkitronic® Norwolf A-Drive

alkitronic® Norwolf X DRIVER SYSTEM

The advanced design: The driver head (X-Driver) is the hydraulic drive with dual-hose system. Fast change without the use of bolts or pins. The X-Driver snaps perfectly into the A-Drive (hexagonal housing) or V-Drive (square housing), thus the drive cylinder is completely protected against damage caused by selective reaction forces that may occur. The X-Driver sits longitudinally, in line with the drive to prevent side loads or torsional forces on the cylinder. This ensures a long service life and safety.Novel articulated joint: Swivel-mounted by 360° or with only one additional element convertible to 360° x 360°.

A-Drive and X-Driver are suitable for more applications than any other torque wrench. Torques from 335-83,000 Nm, hex-agonal outputs SW 27-195 mm (depending on the type).

The patented design of the hexagonal drive ensures the longest reach, allowing for an extremely large angle of attack. This way the hexagon head easily fits on the nut - without rattling or manual adjustment of the ratchet. This design makes the X Driver System the fastest heavy-duty hydraulic torque wrench.

• Slim design - Housing fully closed.• Optional one-piece reaction arm quickly mountable with

two pins• The patented handle lock can be easily loosened with a bolt• Few assembly parts: Other cartridges have many moving

parts, which can consequently lead to more defects and complex repairs

• Incomparable application concept - suitable for all flanges• In tests, the A-Drive is 10-50% faster than other hydraulic

torque wrenches
