The invention discloses a portable material conveyor for power transmission line tower overhaul. The portable material conveyor comprises a case (10), an upright column (20) sleeved in the case (10),a driving mechanism (60) connected with and fixed to the upright column (20), a leading sheave mechanism (40) capable of leading the portable material conveyor for the power transmission line tower overhaul to move along a guide rail (80), and a pallet (50) for bearing and holding a conveyed article. The portable material conveyor for the power transmission line tower overhaul is small and exquisite and light, can be used simply by one operator for tower bottom overhaul, and has the characteristics of disassembly, easiness of transportation and the like, the labor intensity of the operator foroverhaul is lowered substantially, the situation that the operator repeatedly gets on and off a tower to take a tool and goods is avoided, the influence on the safety of an iron tower by equipment islowered, and the problems that the cost is high and the maintenance is not convenient are solved.
