Double Girder
Overhead
Maximum lifting height. Maximum capacity. Twin box girders carry the trolley on top for the highest possible hook position — available to 250 tonnes with ZX wire rope hoists up to 80 T and VX open hoists beyond. Built for steel mills, foundries, and heavy industry.
Double Girder
Overhead
Maximum Lifting Height
On a double girder crane the trolley travels on rails fixed to the top flange of the twin box girders, rather than hanging beneath a single beam. This elevates the entire hoist mechanism and places the hook higher — delivering the maximum achievable lifting height within any given building. For facilities where roof clearance is the critical constraint, nothing outperforms a double girder design. Lifting heights to 32 metres are achievable.
Twin Girder — Double the Capacity
Two full-depth box girders, individually designed to FEM, DIN, VDI, and CMMA norms, carry the trolley load in bending and torsion. This structural redundancy enables capacities from 3 tonnes all the way to 250 tonnes — far beyond the limits of a single girder. Four or eight long-travel wheels distribute the crane load across the runway to match whatever wheel-load limits the building structure allows.
Modular & Fast to Commission
Modular construction saves installation time — components arrive pre-assembled and pre-wired, allowing the crane to be commissioned with minimum downtime. The improved electrical panel is manufactured to international standards with full labelling and simple layout. Speed controllers allow smooth take-off and stop on all axes; braking times, travel speeds, and acceleration can all be fine-tuned on site.
Powerful & Precise — Up to 250 Tonnes
The Cesan Double Girder Overhead Crane is the company's flagship heavy-lifting product — engineered for facilities where capacity, hook height, or continuous duty cycle exceed what a single girder can deliver. Twin box girders, individually designed to FEM / DIN / VDI / CMMA norms, carry the crane trolley on top rails for the highest available hook position within the building structure.
Double girder overhead crane systems are available up to 80 tonnes equipped with ZX electric wire rope hoists, and up to 250 tonnes using the heavier duty VX open hoist. Top-running double girders are designed to run on either four or eight long travel wheels depending on the allowable wheel loads, and multiple trolley gauges are available to accommodate different lifting heights and span configurations.
Multiple trolleys can operate on the same bridge — independently or in synchronised tandem — providing maximum flexibility for complex lift operations. An operator cabin, fixed or travelling along the girder, can be added at any time. For hazardous areas, full Ex-Proof certification is available. Container loading apparatus, type-C hooks, grab buckets, electromagnets, and projector lamps are all standard accessory options.
- Trolley on top of girders — maximum hook height in the building
- Better side hook approach than single girder at large lifting heights
- Maintenance platform standard — safe access along full girder length
- 1 or more hoists on same girder — monorail hoist below girder also available
- 4 or 8 long-travel wheels to match runway wheel load limits
- Special sandblasting + painting to any corporate colour scheme
- Smooth motor/gearbox design — minimum hook swing and minimum abrasion
- Ex-Proof, grab, electromagnet, C-hook, cabin options available

Standard Components
Choose Your Lifting Mechanism
Electric Wire Rope Hoist
High-cycle wire rope hoist for double girder applications up to 80 tonnes. Travels on top-flange rails for maximum hook height. Compact installation dimensions, minimal lateral hook movement, and optimal approach dimensions for safe, precise load handling.
Heavy Duty Open Hoist
The VX open hoist is Cesan's solution for loads from 80 to 250 tonnes — where a self-contained wire rope hoist unit is no longer sufficient. Designed with open drum and gear train, it delivers the structural strength and rope capacity required for the most demanding steel mill and port applications.
Underslung Monorail Hoist
A separate monorail hoist can be adapted below the same double girder — enabling custom two-hook solutions where simultaneous or staggered lifts on the same bridge are required. Can operate independently or in synchronised tandem with the main trolley.
