From the weight of the basic functions of the limiter

From the weight lifting torque limiter limiter and collectively overload protection device. Overload caused by  jib crane  operation is one of the major accident, the light damaged crane parts, so click on overload, structural deformation; heavy causing broken beams, inverted tower, folding arm, the machine overturning a major accident. Using sensitive and reliable overload protection device is to improve the intrinsic safety of the crane, effective measures to prevent overloading the accident.

From the weight of the basic functions of the limiter

1, dynamic load suppression. Overload protection device should be able to distinguish between the actual overload  gantry crane  hanging objects in the normal operation lifting, braking, running and other effects arising from the dynamic load. Hanging objects Guaai (or consolidation with the ground), you should be able to work immediately. Hanging objects caused by the additional dynamic load lifting operation is inherently dynamic phenomenon. Prevent dynamic load effects can be taken latency technologies. However, this delay may be working blind. If within this time stuck hanging objects, the rope tension in a very short time to achieve the degree of damage to the crane, the use of this technology products should solve this problem.

2, automatic job functions. Overload protection devices work properly, you should be able to automatically perform specified functions, should not increase the additional operating the bridge gantry crane  driver.

3, the fail-safe function. Promote product has an automatic safety feature, when failure occurs inside the product, you can send an alarm signal indicative.
