💡 Why do four wheel trolley assemblies work better in strut channel hoist systems?
They are designed to balance load and keep motion smooth under real working conditions.

• Four wheel designs spread weight evenly to reduce bearing stress

• Rubber sealed bearings block dust and improve rolling life

• Solid steel pin shafts increase safety during heavy lifts

• Built-in clearance allows mounting screws without affecting movement

This trolley set is a handy pick when you want smooth hoist travel, solid load support, and a clean strut channel setup without extra hardware getting in the way.
