DWZYZ-SERIES Self-Advancing Tailpiece

To meet the requirements of coal mine heading faces, the belt conveyor self-advancing tailpiece doesn’t adopt the traditional roadheader-towed tail movement method. It resolves issues such as severe floor damage, tailpiece deviation, and potential safety hazards associated with roadheader-pulled tailpieces.

The self-advancing tailpiece connects parallel with the bridge-type conveyor, while its dust removal unit is mounted on the frame and moves synchronously. This configuration enables continuous material transport and rapid tailpiece advancement, significantly improving tunneling efficiency. Equipped with an independent hydraulic power system, the tailpiece securely the ground through its Using the guide rail and frame as mutual pivot points, it achieves step-type self-advancement.

This unit can autonomously achieve mechanized alignment correction (without requiring rib support). This critical technology makes it particularly suitable for complex mine conditions.
Based on the width of the conveyor belt, the tailpiece can be classified into 800 mm and 1000 mm models.

According to the medium used in the hydraulic power system, it can be divided into hydraulic oil emulsion models. Based on the self-advancement stroke, it can be categorized into 1200 mm, 1500 mm, and 2000 mm models.
