Hydraulic tools for torques up to 100.000 Nm
Hydraulic tools manufacturer
We are a manufacturer of hydraulic tools 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.
CARL WALTER hydraulic tools cover high torque ranges (up to 100.000 Nm) and have a very high accuracy, which is up to + / - 3%.
All hydraulic tools have been specially developed for cramped conditions and are therefore characterised by small head radii and an extremely compact design. The optimum ratio of weight and torque was designed and calculated using the latest methods (CAD/FEM). CARL WALTER hydraulic tools are therefore extremely light and user-friendly.
The comprehensive range of accessories for our hydraulic tools ranges from exchangeable cassettes (square cassettes, ring spanner cassettes) to inserts with direct serration and special supports integrated into the system.
The hydraulic tools of CARL WALTER include, among others, the tools of the protected own brand BOLTMAX, which includes the following product types:
- BOLTMAX compact - Compact screwdriver for interchangeable cassettes
- BOLTMAX classic - Square screwdrivers with proven technology
- BOLTMAX xt - Mounting system for plate heat exchangers
- BOLTMAX tension - Hydraulic bolt elongation
- BOLTMAX custom - Special production according to customer requirements.
Due to high torques, use only with power inserts! Of course, we supply special power inserts according to customer specifications (e.g. power or space requirements).
In addition to our standard range, we also design and manufacture special hydraulic tools according to individual customer requirements.
Hydraulic tools - development and special design according to customer requirements
As a manufacturer of hydraulic tools, we have a high vertical range of manufacture in addition to our know-how. The development of hydraulic tools specially adapted to individual customer requirements is therefore one of our core competences. All individual hydraulic tools are developed and designed by our design department in close cooperation with the customer.
- Torque ranges matched to customer requirements
- Individually defined dimensions
- Special inserts, special supports and special cassettes for the corresponding application of the customer
- Batch size 1 to series production
- Optional with factory certificate

Assembly and disassembly system for BOLTMAX xt plate heat exchangers
300 kN
Our assembly and disassembly system for BOLTMAX xt plate heat exchangers achieves a high working speed (approx. 10 min to disassemble a cooler with M39 spindles). Only one operator is required for this hydraulic tool, thus enabling a very efficient working method.
Furthermore, the precise force control (pressure gauge/pressure relief valve) ensures high precision and the various exchangeable components ensure great flexibility. Due to the high safety standards a safe working in hazardous areas (with air hydraulic pump) is possible. In addition, safe working is supported by the fact that the threaded rods are not pressed out. The assembly and disassembly system is also characterised by its compact design and low-maintenance use (no highly loaded gear wheels). A thrust bearing is not required.
The basic BMXTBS system consists of the following five components as standard:
- Cylinder
- Housing
- 5 m hose
- Winding device
- Ratchet.
The system is supplemented by a socket, a split nut and a sw-adapter.
