They are suitable for use widely in factories , mines , wharves, docks, warehouse and engine room for installation of equipments as well as for conveyance of goods. It is especially advantageous for use at the places where no power supply is available and for maintenance and repair of equipments. FEATURES Safe in operation, minimum in maintenance.Compact in construction and minimum dimension for installation. To meet the requirements in use, wheel distance between flanges can be easily adjusted according to the width of monorail.As bearings are mounted on the wheel axle, the trolley are high efficiency in operation with small hand push/pull force.Adopt the special wheel hub surface, the trolleys are apt to run on the flat surface and slant surface with inclination 1:6 and below.The wheels are designed with flanges, the trolleys can run on curved I-beam with smaller radius.
