现在使用的都是具有额定荷载的手扳葫，无法在作业过程中测量判断葫芦所受到的荷载是否在额定载荷值范围内，如果超过了，很可能造成手扳葫芦的链条开断等损坏，大大增加了作业人员及设备风险。荷载检测报警装置是一种能及时测量使用时手扳葫芦所受到的荷载，发生过载时能够及时报警的装置。
Now all the wrenches with rated loads are used. It is impossible to measure and judge whether the loads on the gourd are within the rated loads during the operation. If they exceed the rated loads, they may cause chain breakage and other damage, which greatly increases the risk of operators and equipment. Load detection and alarm device is a device which can timely measure the load of the wrench hoist when it is used and alarm when overload occurs.
荷载检测报警装置设计由测力感应装置、报警感应装置组成。将次装置家装在手扳葫芦的挂点处，在设定好额定载荷后使用葫芦操作时显示屏能及时显示实时荷载并在超过设定的荷载时发出报警信号，从而避免因过载造成的人身、设备事故风险。
The design of load detection and alarm device is composed of force measurement induction device and alarm induction device. The secondary device is installed at the hanging point of the wrench hoist. When the rated load is set, the display screen can display the real-time load in time and send out alarm signals when the load exceeds the set load, so as to avoid the risk of personal and equipment accidents caused by overload.
手扳葫芦荷载检测报警装置工作原理：将荷载检测报警装置与手扳葫芦有机连接组合，通过装置对所受荷载的蒋策报警实现过载保护。
The working principle of the load detection and alarm device of the wrench hoist is that the load detection and alarm device is organically connected with the wrench hoist, and the overload protection is realized by Jiang Ze's alarm device for the loads.
