Torque multiplier for high tightening torques
Torque multiplier manufacturer
We are manufacturers of torque multipliers as standard tools or especially according to individual requirements. Since 1919 we have been developing tools for the most difficult operating conditions and supplying them to industrial companies all over the world.
All torque multipliers of the protected BOLTMAX g-power proprietary brand represent an optimum means of increasing efficiency by multiplying the torques produced by the user many times over with the aid of a planetary gearhead. The BOLTMAX series, consisting of the products Mx, Rx, Lx, and Hx, impress with their compact design, low weight and flexible use in any application.
Extremely long levers (leverage) are not used. The BOLTMAX torque multipliers are also convincing due to their high accuracy (±5%) and the gentle application for screw connections. BOLTMAX g-power torque multipliers should only be used with a torque wrench, not with impact or impulse wrenches! We naturally supply the appropriate wrench for each product.
In addition to our standard range, we also design and manufacture special torque multipliers according to individual customer requirements.
Backstop of the torque multiplier:
- The backstop stores the torque built up. The elastic deformation in the gearbox and screw connection does not have to be overcome again with each ratchet stroke. The backstop prevents the operating tool from kicking back.
Torque multiplier overload protection:
- To protect the gearboxes, the products are equipped with a torsion pin (predetermined breaking point) on the drive side (replacement pin included in the scope of delivery). Sheared off pins can be easily replaced by the user on site using the tools supplied.

Torque multiplier BOLTMAX g-power Mx
100 - 16000 Nm
Our manual torque multiplier Mx forms the core of the BOLTMAX g-power series. The device convinces primarily through its user-friendly design and the large measuring range. This makes the BOLTMAX g-power Mx the ideal companion for every bolting application and enables easy use in confined spaces. Thanks to the supports specially developed for the BOLTMAX g-power Mx, the device is versatile, as they are easy to change. All torque multipliers are supplied with an inclined support as standard or with a straight support on request. Depending on customer requirements, it is also possible to manufacture a special support. For optimum and flexible use, supports on the gear teeth can also be rotated through 360°. In order to be able to transport the unit safely to various locations, the BOLTMAX g-power Mx is supplied in a sturdy case with a moulded insert.

Torque multiplier BOLTMAX g-power Rx
100 - 16000 Nm
Our torque multiplier BOLTMAX g-power Rx features flexible support options and is particularly suitable for work on standard flange and blind flange bolted connections. If there are no or insufficient positions for the support, the BOLTMAX g-power Rx allows support to be provided on the next possible bolt. To do this, the second insert is simply placed on the adjacent bolt, thus providing the necessary support. In order to transfer this possibility to the individual application, the support dimension can be flexibly adjusted. In the slotted hole of the BOLTMAX Rx, the support dimension can be adjusted as required. In addition, great importance was attached to a compact design when designing our torque multiplier, so that it can be used universally for as many applications as possible.

Torque multiplier BOLTMAX g-power Lx
100 - 3200 Nm
The assembly of screw elements and the use of appropriate tools pose great challenges in various areas, such as wind power or plant construction, above a certain height, as they must be light and especially secured. Our torque multiplier BOLTMAX g-power Lx meets the requirements for work at exceptional assembly heights and is therefore ideal for demanding bolting requirements at height. From a safety perspective, the main focus during development was on low weight and a compact design. In addition, the built-in towing eye is ideal for securing the tools. A small housing dimension and the lateral tube support ensure maximum user-friendliness. A high reduction ratio also allows the use of a short torque wrench, as bulky tools in high working areas should be avoided.
