The utility model belongs to the field of hoisting and lifting machines and particularly relates to a door type hoist capable of traveling and operating on a slope. The door type hoist comprises two sets of traveling carts, supporting leg structures, a main beam and a hoisting trolley, wherein the traveling carts are respectively arranged at the left side and the right side; the supporting leg structures are arranged on the traveling carts; the hoisting trolley is arranged on the main beam; each supporting leg structure is specifically formed by a front fixed supporting leg, a rear fixed supporting leg and a telescopic supporting leg which are respectively arranged along a longitudinal slope, wherein a hydraulic cylinder is arranged at the bottom part of the telescopic supporting leg and is specifically used for adjusting the height of the supporting leg structure on the slope so as to keep the horizontal state; and simultaneously a cross shaft is arranged at the bottom part of each supporting leg structure and is used for ensuring that the supporting leg structure is in a vertical state. The door type hoist has the advantages that the door type hoist can be in the horizontal state and the vertical state on the slope all the time by adjustment of the hydraulic cylinder and the cross shafts; and the building of a slope adjusting foundation can be avoided, or the height and the weight of the slope adjusting foundation can be greatly reduced, the construction is simplified, the cost is saved and the construction progress is accelerated.
