CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The trolley moves along the horizontal jib to position loads horizontally. It carries the hoisting mechanism and allows precise placement of loads within the crane's working radius.
Trolleys are typically made of high-strength steel or alloy steel. Structural steel grades such as Q235–Q345 (per GB/T 700) are often used, but the exact material must be confirmed with the manufacturer.
Typical trolley travel speeds range from 10 to 60 m/min, depending on the crane model and application. The actual speed should be verified for the specific trolley.
The trolley is driven by an electric motor connected to a gearbox and drive wheels. The operator controls the motor via signals, and braking systems (mechanical or electrical) stop and hold the trolley. Some systems use rack-and-pinion or friction drives.
