A suspend locomotive is a kind of auxiliary transportation equipment with strong mobility, fast operation speed, large load capacity, as well as safe and reliable driving in a suspended locomotive system. It is mainly used for the transportation of personnel, materials and heavy equipment.
由于井下設備涉及人員設備財產安全，單軌吊設備對行走驅動馬達要求安全可靠，馬達功率密度大，驅動力富有冗余以應對各種突發情況。因此在行走方面，國內外大廠多使用內曲線低速大扭矩方案, 波克蘭液壓作為內曲線馬達的世界領導者， 其解決方案已在知名單軌吊設備商芬瑞特 （Ferrit）、貝克（Becker）等有了成功應用，國內廠商如尤洛卡、常州科試、新遠大等也采用了波克蘭液壓的解決方案。我們的馬達可以為機車提供行進力，馬達上邊安裝著摩擦輪，摩擦輪壓緊在工字梁（軌道）上。泵給馬達供油，驅動馬達轉動，沿著軌道行走。當需要增加高速運行時，配上波克蘭液壓閥塊，可通過旁通作用實現高速運行。
Because underground equipment involves the safety of personnel and equipment property, suspend locomotive requires safe and reliable walking drive motor, high motor power density, and redundancy of driving force to deal with all kinds of unexpected situations. Therefore, applying self-propelled machines, domestic and global OEMs use the cam-lobe low speed high torque solution, Poclain hydraulics as the world leader in the incurve motor, its solutions have been applied by Ferrit , Becker and some domestic manufacturers such as Uroica , Xinyuan, KS, etc. our motor provides the traveling force for the locomotive and propels machine to move along the I-beam. the friction wheel is installed on our motor. The friction wheel presses on the I-beam (track). The pump supplies oil to the motor and drives the motor to rotate and crawl along the track. When the load needs to be increased for high-speed operation, the Poclain hydraulic valve block can play a bypass role and reduce the total driving force.
According to the different torque requirements of the monorail crane, different numbers of motors are required. Generally, one group, that is, two motors provides 20KkN traction, so a 200kN monorail crane needs 20 motors and a 160kN monorail crane needs 16 motors, which is equivalent to the force to lift 3-4 adult elephants.

The suspended locomotive boasts low operation noise, low failure rate, easy maintenance, low price and strong climbing ability. It can realize the overall transportation of large equipment such as hydraulic support. The crawl drive uses a Poclain motor to make the locomotive operation quality more stable and the failure rate lower. It can run safely in the lane with more curves, and can better match the remote driving function and wireless remote driving function.
