The invention provides a trolley walking hollow super-long floating shaft and relates to trolley floating shafts of bridge type cranes. The floating shaft comprises a floating shaft body and shaft ends. The floating shaft body is in the shape of a slender tube. The two ends of the floating shaft body are provided with the shaft ends. The shaft ends are short column bodies. Each shaft end is provided with a boss in the middle. The external diameter of the shaft body of one side of each boss is identical to the internal diameter of the floating shaft body, and the shaft body of the side of each boss is fixed in the tube body. The shaft body at the other side of the boss is connected to a wheel shaft through a shaft coupling. The floating shaft is of a hollow structure, and the two ends are provided with short shaft ends. The hollow structure relieves the shaft deadweight, reduces the deadweight deformation, and suits the transmission design demand of a super-long shaft on a wide span trolley without adding a bearing seat in the middle of the floating shaft for support. The processing technology is simple. It is convenient to install and maintain the floating shaft. The super-long shaft is safe and reliable, and has a low fault rate.
