Quenched and tempered RUD round link chains.
For decades, quenched and tempered RUD round link chains have been used in manual chain hoists, pneumatic chain
hoists and electric chain hoists. The reason: Very good wear resistance and a high level of safety for the user.
Solid through and through - version T
- for all wear stresses EN 818-7-T
- for use in manual hoists such as spur gear hoists or ratchet hoists or ratchet hoists
For special requirements - version VH
- for applications in manual hoists ISO 16872
- on request
