The invention provides a door frame support of a forward-movement type forklift. The door frame support comprises an L-shaped door frame support body. Adjustable side wheel assemblies, side wheels and adjustable main wheels are symmetrically arranged on the horizontal sections of the two sides of the door frame support body. Main wheels are symmetrically arranged at the bottom ends of the vertical sections of the two sides of the door frame support body and are moved on the upper end faces of forklift body guide grooves. The adjustable side wheel assemblies, the side wheels and the adjustable main wheels are located in the forklift body guide grooves and are moved after the fit clearances between the adjustable side wheel assemblies, the side wheels and the adjustable main wheels and the inner surfaces of the forklift body guide grooves are synchronously adjusted. The fit clearances between the adjustable side wheel assemblies, the side wheels and the adjustable main wheels on the door frame support and the forklift body guide grooves can be adjusted, and therefore the stability and reliability of a door frame in the working process are ensured.
