AI Technical Summary
Existing loader test counterweights are only applicable to models with the same rated load, and cannot be used for loaders with different loads. This forces loader manufacturers to equip their loaders with various counterweights of different specifications, increasing the cost of test counterweights.
Design a test counterweight system that includes a main counterweight and a detachable counterweight block. By setting a positioning sleeve and a positioning pin on the main counterweight, and the cooperation between the limiting groove and the limiting block, the counterweight block can be quickly disassembled and fixed, which is suitable for loaders with different loads.
This system enables the same test counterweight system to be used on loaders with different loads, reducing the investment cost of test counterweights and improving test efficiency and device reliability.

Abstract
Claims
1. A break-in weight for a loader characterized by, It includes a main counterweight and counterweight blocks, wherein multiple counterweight blocks are provided and the multiple counterweight blocks are detachably connected to the main counterweight; A placement groove is provided on the upper part of one side wall of the main counterweight. A first positioning sleeve is fixed at the upper part of both side walls of the main counterweight near the placement groove. Positioning pins are fixed on both side walls of the counterweight block by fixing blocks. The positioning pins are correspondingly set with the first positioning sleeves.
2. A test weight for a loader as set forth in claim 1, wherein, The lateral depth of the placement groove is a multiple of the thickness of the counterweight.
3. A test weight for a loader as set forth in claim 1, wherein, The length of the main counterweight is less than the width of the loader bucket.
4. A load test weight for a loader as set forth in claim 1, wherein, The length of the counterweight is the same as the length of the main counterweight.
5. A test weight for a loader as set forth in claim 1, wherein, The bottom surface of the placement slot is provided with multiple limiting slots, and the bottom surface of the counterweight is provided with multiple limiting blocks, with the multiple limiting slots corresponding to the multiple limiting blocks.
6. A break-in weight for a loader as set forth in claim 1, wherein, The counterweight is further provided with a second positioning sleeve on both sides of the sidewall. The second positioning sleeve is located on the side of the counterweight away from the positioning pin.
7. A test weight for a loader as set forth in claim 6, wherein, The second positioning sleeve is set in correspondence with the positioning pin.
8. A break-in weight for a loader as set forth in claim 1, wherein, The main counterweight is also provided with a slot, which is located below the placement slot.
9. A test loader counterweight as described in claim 8, characterized in that, The outer edge of the top wall of the slot is arc-shaped.
10. A test weight for a loader as set forth in claim 1, wherein, Both the main counterweight and the counterweight block are equipped with lifting rings on both sides of the top.
