What is A Type MG Double Girder Hook Gantry Crane
Double glider gantry cranes with hook are available for general service, such as loading, unloading,lifting and transferring work in outdoor storage oron railways.
Features of A Type MG Double Girder Hook Gantry Crane
Robust Build Design
Welded Steel Framework: Main girders and support legs are constructed using high-strength welded steel (offered in Type A or Type U designs), ensuring long-term reliability in outdoor settings such as storage yards and rail terminals.
Twin-Girder Configuration: Delivers greater lifting capacity (standard range: 5–500 tons, customizable up to 600 tons) and improved stability over single-girder cranes.
Common setup includes:
Box-type welded bridge frame
Independently driven travel systems
Complete electrical control package
Fully equipped operator cabin
Accurate Control & Operation
Independent Drive Units: Utilize integrated reducer mechanisms for simplified upkeep and consistent performance.
Dual Power Supply Choices:
Flexible cable drum system (left or right mounting)
Fixed conductor rail setup
Advanced Safety Systems
Integrated Safeguards:
Load limiter
Wind speed monitoring
Axle breakage prevention
Anti-overturning device
