CraneVeyor 4036/Z-Series Crane
CraneVeyor manufactures a complete range of underhung cranes with structural beam girders. The cranes are available from ¼ ton push/pull type to 20 tons capacity long span, multiple runway type. We manufacture our end trucks and have CNC machinery to turn wheels and mill assemblies, and efficient jigs to align the assemblies. You’re buying these hard working, cost effective cranes from a manufacturer with over 64 years of know-how.
Underhung Crane
CraneVeyor offers Underhung Overhead Cranes, including the 4036 Series (up to 3 tons, 30' span) and Z Series (1–15 tons, up to 60'+ spans). Z Series cranes feature flangeless wheels and friction tire drives for durability and smooth operation.
Additionally, Double Girder and Multiple Runway Cranes provide higher capacities (up to 30 tons) and low headroom for long-span applications.
