The invention relates to the technical field of electromechanical integration, in particular to a load bearing vehicle capable of stepping forwards to climb a mountain. The load bearing vehicle comprises a vehicle body, a direct-current motor, a driving wheel, reverse consequent gear, a driven wheel, a bearing bush, a steering gear, a steering wheel, a connecting rod, a connecting rod foot sleeve, a guide rail, a straight bar gear, a lifting foot, a travel switch, a steering yoke, a push rod, a baffle, a spring, a ball, a direct-current meter, an up stroke and down stroke cycling circuit of the direct-current motor and a storage battery. The load bearing vehicle can walk with a load on gullies, gravel, grass and a mountain range with a gentle slope with the gradient lower than 45 degrees. The load bearing vehicle is scientific in design and reasonable in structure, thereby surely becoming a specific transportation vehicle for uphill and downhill delivery of goods in the future.
