MINE HOISTS
pressure and deceleration / acceleration from sensors on the brakes and compares them to pre-defined setpoints . If the values differ , a suitable corrective , modulated change is communicated to the brakes to adjust their action accordingly .
In this application , the most suitable brakes to integrate with SOBO iQ were identified as VKSD58 spring-applied , hydraulically released calliper disc brakes from Twiflex , another brand within Altra Industrial Motion . As a global leader in innovative braking solutions designed to provide years of reliable performance , the company ’ s solution is well equipped to withstand the challenging operating conditions found in mines .
Furthermore , by relying on member companies within Altra , the hoist producer could benefit from a one-stop-shop for its braking needs . In particular , the two brands could leverage a strong , close collaboration to deliver matching components for a fully integrated solution while also offering a single point of contact to the hoist manufacturer .
The spring applied callipers would assure operators that braking would be maintained in the event of electrical supply system failure as well as supplying sufficient braking force , as the VKSD series can reach over 100 kN . In addition , to deliver a system that would fully address the requirements of the mine hoist OEM , Twiflex
leveraged its in-house design and manufacturing capabilities to create the bespoke brakes .
The resulting solution consisted of SOBO iQ communicating with VKSD58 callipers with proximity switches acting on a pair of discs that were shaft-mounted to the hoist ’ s cable reels . For this project , the elevator machinery manufacturer could benefit from advanced application expertise from Svendborg Brakes and Twiflex , which proved crucial to specify , integrate and customise the braking systems .
