出装置。[Claims for Utility Model Registration] 1. A load detection spring is interposed between the upper end of the piston rod of the lift cylinder and the inner mast interlocked with the fork, and a detector is provided to detect compression of the load detection spring. A forklift load detection device characterized by the following: 2. An inner mast that is raised and lowered by a lift cylinder is installed on the outer mast erected at the front of the vehicle body, and a carriage that is guided up and down by the inner mast to support the fork, and an outer mast connecting member that is connected to the outer mast. In a forklift in which the forklifts are connected by a lift chain via a sheave installed at the upper part of the inner mast, a load detection spring is inserted between at least one of the lift chain anchor and the carriage or between the lift chain anchor and the outer mast connecting member. 1. A load detection device for a forklift, characterized in that a detector is provided for detecting compression of the load detection spring. 3. A mast that guides the fork in a vertically movable manner is provided at the front of the vehicle body so as to be swingable around an axis in the width direction of the vehicle body via a mast support, and a tilt cylinder for tilting the mast is provided between the mast and the vehicle body. 1. A load detection device for a forklift, characterized in that the forklift includes a load detection spring interposed at the tip of the piston rod of the tilt cylinder, and a detector for detecting compression of the load detection spring.
