The invention discloses a crane pedestal. The crane pedestal comprises an underframe, a slewing gear ring, a slewing bearing and a power device, wherein the slewing gear ring is fixed on the underframe; the slewing bearing consists of a bearing inner ring and a bearing outer ring, and the bearing inner ring is fixed on the underframe and has the position coaxial with the slewing gear ring; the power device comprises a motor and a wheel gear, the motor is directly or indirectly fixed on the bearing outer ring, and the wheel gear is fixed on a rotor shaft of the motor and engaged with the slewing gear ring, so that the bearing outer ring is driven by the motor to rotate relative to the underframe. The crane pedestal has the beneficial effects that the crane pedestal is small in floor occupation area, and can be constructed in a construction site with an extremely limited space; the crane pedestal is composed of removable light and small components, thereby being more beneficial for carrying, disassembly and assembly; and a transmission device of the crane pedestal is protected by a protective cover and runs completely through remote control, thereby being safer when in use.
