1. Introduction
The LBJ Series standard load testing machine is a measuring instrument for force value calibration, which
can be used for tensile and compression tests.It is mainly composed of main machine, table type electric
control cabinet and computer system.

2.2 Weight and its drive mechanism
There are 19 independent weights, and the hanging component can be counted as a weight with a total
mass of 10100N. It can apply a load of no more than 1000N and a minimum rating of 100N.
The loading or unloading of the weight is determined by the pallet lifting of the weight, and the lifting of the
weight pallet is determined by the highest and lowest points of the cam. The cam mechanism is realized by the
rotation of the micro motor. Therefore, the micro-motor is used to make the weight tray move up and down
linearly by the cam mechanism, and the downward movement is performed to complete the loading and
unloading of the weight, and the upward movement is performed to complete the unloading of the weight. Each
weight is driven by a synchronous micromotor drive mechanism, together with the tray slider, guided by a linear
guide, by loading up and down linear motion (applying to the bracket of the boom), or unloading (from the
suspension of the boom) Remove from the block).The loading or unloading process of the weight is completely
completed by the proximity switch to the microcomputer control system.
3. Control System
Adopt Japanese Panasonic PLC control system, computer operation method, automatic loading and unloading.
Automatically collect data, store, and automatically print test reports. With security protection {emergency stop}China ibutton switch.
4. Operating software
The software system is designed and developed by the our company. It has real-time monitoring of running
status, real-time display of the number and position of weight loading, etc. It has real-time pause, one-key
recovery, automatic unloading and other functions.
