HOME OFTORQUE POWER

alkitronic® - Wind energy partners YOU HAVE THE APPLICATIONS. WE HAVE THE SOLUTIONS. Wind turbines need to withstand high environmental impact. Many tons of weight must be held at lofty heights with absolute reliability. Especially under extreme forces or weather conditions, highly precise, wind-proof bolting techniques are crucial for success. The alkitronic® product range is characterised by complete system solutions for bolted connections in wind turbines.

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 results in enormous savings in work time. Other advantages of continuous turning are higher precision due to the precise...

From 75 to 6,500 Nm, ip = Protection class IP54 Battery-driven torque multiplier from 90 to 4,000 Nm From 400 to 42,500 Nm, optionally with LC Display EFCip in an angled version with OLED display From 370 to 10,000 Nm, 2-gear torque multiplier EF with an angled gear and analog control 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...

Hydraulic torque wrenches

HOME OF TORQUE POWER 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...

Hydraulic torque wrenches alkitronic® AX and AT 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...

HOME OF TORQUE POWER alkitronic® Norwolf X DRIVER SYSTEM The advanced design: The driver head (X-Driver) is the hydraulic drive with dualhose 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...
