The invention discloses a mast-type lifter. The mast-type lifter comprises an upper mast set, a lower mast set, a supporting platform, an operating platform and a master control device, wherein the upper mast set is connected with a first motor; the lower mast set is connected with a second motor; the supporting platform is used for fixing the lower mast set; the operating platform is fixed to the top of the upper mast set; the master control device is used for controlling the first motor and the second motor to be turned on or turned off; and the first motor and the second motor are fixed to the supporting platform and connected with the master control device. The mast-type lifter has the beneficial effects that sectional type lifting of the mast-type lifter is achieved, and it is ensured that the whole mast-type lifter can be kept at the same speed during lifting while the whole lifting height of the mast-type lifter is increased; the phenomenon that workers are injured due to changes of the lifting speed is avoided; meanwhile, masts in the upper mast set and the lower mast set can be lifted at the same speed, it is ensured that the operating platform of the mast-type lifter can be horizontally lifted, and stability and safety are improved.
