Influence of Ropeway Span on Tension Travel of Passenger Ropeways

Tourism and winter-sports growth boost passenger-ropeway applications. Common types: circulating detachable-grip, circulating fixed-grip and reciprocating ropeways. Ropes wrap around drive wheels and deflection wheels. Supports and sheave groups are arranged along the route. Tensioning devices keep rope tension within safe limits.

1. Relationship Between Tension Travel and Wire-Rope Splicing Length

Tension travel determines required rope-splicing length. - Too short splicing → insufficient tension travel and hidden safety risks. - Too long splicing → early re-splicing and higher maintenance costs.

Definition: Tension travel is the displacement of trolleys or counterweights between full-load and no-load conditions under constant rope tension.

2. Three Main Tensioning Systems

1. Hydraulic Tensioning System

Consists of trolley, hydraulic power station, cylinders and oil fittings. It maintains constant rope tension. When load changes, the trolley moves back and forth driven by hydraulic cylinders to stabilize rope tension and meet national safety-factor standards.

2. Counterweight Tensioning System

Made of counterweight units, anchorage barrels and guide wheels. Counterweights move up and down by gravity to automatically adjust rope tension as passenger load varies.

3. Double-End Anchorage Tensioning System

Both rope ends are pre-anchored with pre-set tension. Calculations define safe tension thresholds. Tension stays within safe ranges under changing loads.
