Due to the weight of the steel drag chain itself and the weight of the built-in cables, oil pipes, air pipes, and water pipes, the drag chain itself has an unsupported length limit. Drag chains of different models and materials have different unsupported length limits. If the length of the steel drag chain required exceeds this unsupported length limit, it will sag. We can solve it in the following three ways:
First, you can use guide grooves. The guide trough consists of five parts: standard length side guide wall, guide trough connecting angle steel, mounting screws, bottom trough, and sliding device. The sliding device is divided into several types of nylon wheels, steel sliding plates, and plastic sliding plates. In this way, the guide grooves are correspondingly divided into three types: guide grooves with plastic sliding plates, guide grooves with nylon wheels and guide grooves with steel sliding plates.
The second is to use support rollers. If the support wheel can be fixed on the equipment, the support wheel without a support frame can be used directly, and the drag chain rack runs back and forth on the support wheel. If the support wheel cannot be fixed on the equipment, a support wheel with a support frame can be used. The support wheel is fixed on the support frame, and the drag chain frame reciprocates on the support wheel.
The third is to perform heat treatment and chain thickening processes on the steel drag chain links. Chain pieces can also be made of 304, 430 and other materials.
