Product details
Supplied as an assembly, the SS977 pairs a ball-bearing overhead trolley with an SS912 shackle. The trolley body is stainless steel 304, while the shackle is stainless steel 316 in size M12. It is designed for 8 mm cable, and the complete unit weighs 854 g. It belongs to the overhead lifeline components of the via ferrata range.
The shackle gives a ready connection point beneath the trolley for a lanyard, energy absorber or self-retracting device, and the ball bearing helps the trolley follow the user along the cable. Overhead systems of this kind are used above loading bays, gantries, workshops and maintenance routes. The related SS980 trolley is offered without the shackle and with a published breaking strength.
Buyers should request the breaking strength of the SS977 and confirm it against the system design, along with compatibility with the brackets in use. The SS977 can be produced as OEM or private label, or adapted to a customer drawing.
