The invention relates to a hoisting trolley. The hoisting trolley comprises a hoisting mechanism, a traveling mechanism and a machine frame used for mounting the hoisting mechanism and the traveling mechanism, wherein the hoisting mechanism comprises a reel and a reel driving device; the traveling mechanism comprises traveling wheels and a traveling driving device; the reel is rotationally connected with the machine frame; the reel driving device drives the reel to rotate by using a built-in multi-disc brake permanent magnet motor as a prime motor; a driving output gear of the reel driving device is meshed with an inner gear ring of the reel; a multi-disc brake device is arranged in the rear part of a rotor of the built-in multi-disc brake permanent magnet motor; during non-energization, a brake elastic device pushes a brake disc assembly to form braking; after energization, the braking force exerted on the brake disc assembly by the brake elastic device is removed by a switching-off power device. The hoisting trolley is light in weight, small in size, wide in speed regulating range, convenient to operate and control, safe and reliable, and the manufacturing cost and the operation cost can be obviously reduced.
