Product Introduction
When a port gantry crane smoothly strides across the tracks, precisely lowering a 60-ton container onto a cargo ship; when a steel mill overhead crane shuttles across a 100-meter-long workshop, hoisting 100-ton steel coils; when a shipbuilding gantry crane lifts a 1,000-ton ship section—behind these "industrial ballets" lies the "power heart" of the crane's travel motor. It drives 10,000-ton loads with millisecond response and controls movement with millimeter-level precision, acting as a silent yet crucial "pacemaker" in the global logistics and manufacturing network.
Classification and Decoding: Precise Adaptation from "Small and Flexible" to "Giant"
The world of mobile motors is born from application scenarios and evolves with demand:
DC motors: The "flexible tool" for small cranes. Their structure is as simple as "mechanical Lego," yet their reliability rivals that of a Swiss watch. In light-load applications (such as single-beam cranes suspended in workshops), they operate safely at 24 V, making them particularly suitable for retrofitting and upgrading older factories.
AC asynchronous motors: The "efficiency engine" of small and medium-sized equipment. Their power density is as high as an "energy cube," with starting torque reaching 2.5 times the rated value. A 5-ton single-beam crane in an automobile assembly plant, equipped with a 15 kW AC asynchronous motor, reduces its lifting cycle from 3 minutes per lift to 90 seconds per lift.
AC variable-frequency motors: The "intelligent brain" of large equipment. Their speed regulation accuracy reaches ±0.1%, like a "stepless speed valve" for the motor. At the automated container terminal, the RMG (rail-mounted gantry crane) uses a 37 kW variable frequency motor and, coupled with an AI scheduling system, can load and unload 40 TEUs per hour, equivalent to the efficiency of 80 workers.
Hydraulic travel motors: the "power king" of heavy equipment. With torque output comparable to an industrial hydraulic hammer, the dual hydraulic motor drive system on a 300-ton shipbuilding gantry crane allows the crane to move a 1,000-ton ship at a speed of 0.5 m/s, with zero impact during start-up and shutdown, and reduces track wear by 40%.
