About SREE

Find Your Optimal Solution Quickly

SRLK-TL

Stereoscopic warehouse (AS/RS) for coil strip storage with automated in/out handling. Designed to integrate with slitting lines, cut-to-length lines and workshop logistics as part of an intelligent CRGO workshop.

SRWL Series

Intelligent logistics system for transformer manufacturing workshops, enabling automated material transfer (e.g., RGV/AGV) across key processes such as casting & drying, testing, core/coil drying and oil filling.

SRDZ 2200

Intelligent high-speed stacking machine for transformer core laminations. It can grab five sheets (one core layer) simultaneously and stack two CRGO cores at the same time.

SRDZ 1500

Intelligent core stacking line for medium power transformer cores. Feeding from both sides with central core discharge; magnetic-levitation gantry travel and vacuum sheet handling keep stacking accurate over long production runs.

SRDZ 1300

Intelligent core stacking line for small and medium power transformer cores. A gantry with vacuum suction cups stacks laminations automatically; magnetic-levitation travel avoids screw and gear wear for stable long-term accuracy.

SRHJ400-223C

Transformer-core cut-to-length line with upper & lower log stacking arms. The upper arm stacks 2 logs and the lower arm stacks 3 logs, forming 5 logs (2 yokes, 2 side legs, 1 center leg) for a complete core lamination in one assignment.
