Engineering a 20t double- girder crane for heavy precast concrete manufacturing


Overhead cranes play an important role to ensure consistent production, and designing a crane requires careful considerations of all that’s entailed. OCH hears from Zelus Material Handling, as it expands on its recently completed design and supply of a 20t, top-running, double-girder overhead crane for a precast concrete manufacturing facility in Atlantic Canada.

Designing a system for this environment requires consideration of structural demands, operational workflow and reliability.

girder overhead crane for a precast concrete manufacturing facility in Atlantic Canada. The crane was engineered to support demanding production requirements while meeting applicable safety and performance standards.


Application driven design The manufacturing environment required a crane capable of handling large precast components with stability and precision. Load weights


approach the upper capacity range on a routine basis, and crane motion must remain smooth to prevent load swing and minimise handling time. During the design and approvals stage, the


customer communicated a critical operational requirement. The new crane needed to match the performance characteristics of an existing Kone crane already operating in the facility. The plant routinely performs multi-crane lifts for large bridge girders, with five overhead cranes sharing the same


A double-girder configuration provides the stiffness and stability required for heavier loads while supporting smooth trolley travel. ochmagazine.com | Spring 2026 13
