TP-978 Aluminium Zipline Pulley with Stainless Steel Sheave

TP-978 is built for zip-line use: the case is aluminium alloy, the sheave is stainless steel for wear resistance on the line, and a ball bearing keeps rolling resistance low. The listed load is 25 kN and the maximum rope size is 13 mm. The first image is a dimension drawing of the pulley body.

Adventure parks, challenge-course operators and zip-line builders use trolleys like TP-978 for rider transport along a cable or rope, with the rider connected below by a lanyard or connector. In Europe, ropes courses including zip lines are designed and operated under EN 15567, and in North America ASTM F2959 is a common reference for aerial adventure courses; both affect how operators specify trolleys and braking.

Buyers should state the cable or rope type and diameter, expected speeds, braking method and the compliance route they need. Power Honour can supply TP-978 as private-label equipment and can modify case or sheave details to a customer drawing.
