Equipment hard box with telescopic pull rod

WEISHUO's Equipment hard box with telescopic pull rod is specifically developed to solve the challenges of moving medium to heavy equipment. Traditional protective cases are laborious and inefficient to carry manually when the equipment is heavy or the movement distance is long. This product cleverly combines the convenient pull rod design of a suitcase with the reliable performance of a professional protective case. Through the combination of a telescopic pull rod and silent wheels, equipment weighing over 15kg can be moved easily, greatly reducing worker fatigue and improving work efficiency.
