Safety First What is the highest priority in the design of SFTdriveshafts? The safety of the operator. Nothing contributes to safety more than an experienced and cautious operator, but a quality driveshaft, designed with safety in mind, can sometimes make the difference. Not only does the SFT range comply with existing international safety standards, it is also designed to go beyond those criteria to create a new bench mark for safety. Work, work, work What is required from a driveshaft during those times when one cannot afford downtime? It is expected to work, continuously. SFT driveshafts are...
