Abstract
The utility model discloses a truck-mounted crane with a protector. The truck-mounted crane comprises a transporter for transportation and a lifting device for lifting, wherein the lifting device comprises a lifting arm and is provided with a steel wire rope for lifting; a hook is arranged at the lower end of the steel wire rope; and a load limiting device is arranged on the steel wire rope. The truck-mounted crane has a simple structure and is ingenious in design; and when the truck-mounted crane is used, a telescopic rod on the load limiting device is pulled down when the hook bears excessive weight, and when a check block on the telescopic rod reaches a detection switch, the detection switch outputs a signal to an alarm and the alarm makes sounds to give an alarm, so that operators can be reminded of reducing the weight on the hook to achieve the effect of protecting equipment. The truck-mounted crane is a new technical scheme and is convenient to popularize.
