Abstract: A load carrying apparatus with security detection system provided in accordance with the present invention comprises: a base includes a vertical connecting rod and a plurality of cantilevers welded at peripheral surface of the connecting rod, the respective cantilevers are provided with a hook; a security detection system includes a plurality of strain meters being secured to the respective cantilevers of the base and located close to the connecting rod. When a load is hanging from the cantilevers, the cantilevers will be deformed, and the security detection system will detect a deformation of the detection system and output data.

Abstract: A digital pointer indicator includes a signal output unit, a microprocessor unit, a digital display unit, and a pointer unit. The pointer unit includes a digital/analogue conversion control unit, a step motor, and a pointer. A thick film unit is connected between the digital/analogue conversion control unit of the pointer unit and the step motor, and it can provide pretty low impedance, so it is able to control a current of the digital/analogue conversion control unit precisely when the digital impulse signal is being transmitted, the rotation of the step motor is micro adjusted accordingly, and thus improving precision of the weight measurement.

Abstract: A digital type pointer indicator includes a signal output unit, a microprocessor unit, a digital display unit, and a pointer unit. The pointer unit includes a digital/analogue conversion control unit, a step motor, and a pointer. Thus, the digital type pointer indicator provides a digital indication manner and a pointer indication manner simultaneously, so that the user has two value reading manners, thereby facilitating the user identifying the value of the weight of the object to be measured.
