Bridge Grab Bucket Ship Unloaders

Bridge Grab Ship Unloaders are designed for bulk cargo unloading operations from barges and seagoing vessels, serving as a core equipment in bulk terminals for discharging commodities such as coal, ore, and grain. Utilizing traditional grab bucket opening/closing and hoisting mechanisms to handle materials, they offer proven reliability, high maneuverability, and minimal maintenance requirements. Bridge Grab Bucket Ship Unloaders’ unique advantages—adaptability to diverse cargo types and vessel configurations, lower operational costs, and resistance to damage from wave-induced vessel movements—make them irreplaceable compared to other unloading methods.
