How to solve the problem of long-distance sagging of steel towline

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. Different types and materials of drag chains have different unsupported length limits. If the length of the steel drag chain is required to exceed this unsupported length limit, it will sag.

We can solve it in the following three ways:

1. We 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, Steering Drag Link steel sliding boards, and plastic sliding boards. 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.

2. We can use support rollers. The support wheels that can be fixed on the equipment can directly use the support wheels without the support frame, and the tow chain frame reciprocates on the support wheels. 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.

3. Heat treatment and thickening of the steel towline chains can also be carried out. The chain can also be made of 304, 430 and other materials.

In summary, for the long-distance operation of steel drag chains to prevent sagging, we can use guide grooves, use support rollers, heat treatment and thicken the drag chain links.
