STAHLWILLE: Working safely in live conditions 02 February 2024

STAHLWILLE has received VDE approval for its MANOSKOP 730 VDE torque wrench in two sizes – making them the only models on the market that can be readjusted without disassembly. The same applies for the approval compliant replacement of the ratchet – without having to carry out a new breakdown test. 

STAHLWILLE explains that being able to replace the ratchet in-house without sending the tool out for a new VDE test considerably reduces the effort and costs involved in such testing procedures, as well as making handling the tools in the field much easier.

VDE approval for two versions

Approval was granted for two versions with different measuring ranges and lengths. The MANOSKOP 730R/2.5 VDE has a measuring range from 4Nm to 25Nm and an overall length of 335.5mm. The larger version, the MANOSKOP 730R/5 VDE, is designed for 10Nm to 50Nm with an overall length of 390.5mm. The handle casing of both tools is made of double insulated plastic to enable VDE compliant work at voltages of up to 1,000 volts. The insulation consists of a very slip resistant, glass fibre reinforced polyamide plastic. This is resistant to liquids frequently found in working environments, such as alkaline solutions, fuels and oils – making them ideal for tough usage conditions.

The MANOSKOP 730 VDE is a mechanically setting/clicking torque wrench. When the set value is reached, a clearly perceptible double stop signal is emitted. As with all tools from this STAHLWILLE series, it is not necessary to reset to ‘0’. Instead of a spring, a low wear trigger system with a switching edge is used. The measuring element is only loaded when it is tightened. The trigger mechanism is not subjected to any further load after triggering, thus reliably preventing damage. There is no switchover function for loosening existing screw connections. This prevents incalculable forces when loosening existing screw connections.

Professional features of the MANOSKOP 730 VDE include a square drive with QuickRelease safety lock for reliable locking of the insert tool. Torques can also be set without effort thanks to the QuickSelect quick adjustment. The user simply pulls the adjustment knob and it is set and secure. The double scale with colour-coded display of different units of measurement is also very easy to read and enables precise fine adjustment.

Extensive VDE range

Both torque wrenches are part of an extensive VDE range from STAHLWILLE. Developed with practical everyday use in mind, the selection comprises more than 130 tested VDE products, which feature an ergonomic design, low tolerances and a long service life.

The VDE compliant torque wrenches, fine tooth ratchets, combination wrenches, screwdrivers, and pliers, are offered individually and in usage oriented sets that are easy to store and transport. In addition to stackable socket set boxes, there are roll cases and a 48 piece VDE tool set in a tool case – especially for applications in the area of electric mobility. The range also includes socket wrench and screwdriver bits, including for TORX® drives and Allen screws.
