Complete solution from SCHAAF The accessories for the HDL Series such as hydraulic hoses, connection couplings, as well as the hydraulic high-pressure tools such as bolt tensioners and hydraulic nuts are aligned to the functions = 100 % system solution.

Areas of Application

The SCHAAF HDL Series is ideally suited for:
  • The use of bolt tensioners, hydraulic nuts, ExpaTen Bolts and EcoRolls
  • Tightening and loosening of oil press fits (e.g., gearwheels, flywheels, coupling hubs, roller bearings, hydraulic couplings and overload protection devices)

Quality Assurance

All HDL 1000-4000 are checked for material quality, dimensional accuracy, correct functioning and load-resistance. During order execution, they are subject to continuous quality assurance measures and are supplied together with detailed technical documentation.



HDL 1000-4000 are, of course, oil filled and ready for immediate use. SCHAAF HDL 1000-4000 are user-friendly, reliable, and manufactured in accordance with the highest level of technical know-how. Our highly-motivated staff would be pleased to train your personnel, in situ or at our works, in the general handling and operation of highpressure equipment.
