PURPOSE: A safety device for measuring the load of an enplanement of a tower wagon is provided to conveniently detect the load of an enplanement by making an axial-type load cell entirely transformed even if the enplanement is inclined due to weighted load. CONSTITUTION: A safety device for measuring the load of an enplanement of a tower wagon comprises a boom stand, a boom take-out unit(2), an enplanement, a connection unit(4), and a hydraulic driver(5). The boom take-out unit is located in the boom stand. The connection unit comprises a fixed bracket(41), a moving bracket(42) and a telescopic cylinder(45). The fixed bracket is fixed to the highest boom. The moving bracket is connected to the front of the fixed bracket through a first shaft connection part(44). The moving bracket is connected with the enplanement using(43). The telescopic cylinder is connected between each front sides of the fixed bracket and moving bracket using second and third shaft connection parts. The hydraulic driver drives the enplanement connection unit. The third shaft connection part comprises a first axial-type load cell(472) which is transformed according to the load variation. |
