Ang teknolohiya ng dumper ng kotse ng Sino Coalition ay nangunguna sa China at umabot sa internasyonal na advanced na antas. Ito ay nagdisenyo at gumawa ng halos 100 set ng Single-car dumpers, Double-car dumpers,Triple-car dumpers, Quadruple-car dumpers at iba pang produkto ng iba't ibang uri, ang maximum design material dumping capacity ay 8640 tonelada / oras. Ang domestic market share ng medium at large dumpers na may higit sa Double-car dumper ay higit sa 80%.
Ang single-car dumper system, ayon sa layout form, ay maaaring nahahati sa fold-back type at through-type.
Ang karaniwang fold-back na single-car dumper system ay binubuo ng: car dumper + car puller + car pusher + single transfer platform + wheel clamp at stopper.
Karamihan sa mga domestic single-car dumper system ay nasa fold-back arrangement.
Ang through-type na single-car dumper system ay binubuo ng: car dumper + car puller + car pusher + wheel clamp at stopper.
Ang double-car dumper system, ayon sa layout form, ay maaaring hatiin sa fold-back type at through-type.
Ang high-efficiency na double-car dumper system ay binubuo ng: double-car dumper +car puller + car pusher + double-car transfer platform + wheel clamp, high-level stopper at movable buffer stopper.
Ang fold-back triple-car dumper system ay binubuo ng: triple-car dumper + heavy-duty shunting machine + light-car shunting machine + car pusher + three-car moving platform + wheel clamp at one-way stopper.
Ang single-car dumper ay maaari ding hatiin sa C-shaped Single-car dumper, U-shaped Single-car dumper at O-shaped dual-purpose single-car dumper.
Ang double-car dumper ay maaari ding nahahati sa C-shaped Double car dumper at O-shaped Double-car dumper.
Ang triple-car dumper ay maaari ding hatiin sa C-shaped Triple-car dumper at O-shaped Triple-car dumper.
