  • Detail

Automatic control system of bridge type grab ship unloader

grab ship unloader is the key equipment for loading and unloading coal, ore, grain, fertilizer and other bulk cargo in port, power plant, metallurgy, chemical industry and other industries. In the past, such electrical control systems mainly rely on imports

Haide company is committed to the electrical automation of large lifting equipment. According to a large number of engineering practices and the digestion and absorption of international advanced technology, it has independently developed an advanced semi-automatic bridge grab ship unloader automatic control system, which has been widely used and praised

system features

high operation efficiency - semi-automatic cycle, trajectory optimization, grab deep excavation control

reduce labor intensity - grab automatic operation, semi-automatic cycle operation, high degree of automation, less manual intervention

prolong mechanical life - electronic speed regulation and grab automatic control, no impact, motor output balance control

powerful management functions - graphic monitoring management system, productivity statistics Report generation and with the increasing requirements of consumers for food packaging, printing

safe and reliable - high-quality product integration, perfect protection and fault detection and processing system

simple maintenance - power distribution animation monitoring, real-time and historical fault records, perfect maintenance instructions

considerate service - remote diagnosis Timely on-site service Mr. chenchengsi, chairman of Ningbo Dacheng new materials Co., Ltd.
