Comansa Crane 21CM335 with 18 Ton Lifting Capacity for Sale
Comansa 21CM335: A Versatile Flat Top Tower Crane
The Comansa 21CM335 flat top tower crane offers two versions, each with impressive capabilities. It can handle a maximum load of either 12 or 20 tonnes. With a maximum radius reaching up to 74 metres, it provides extensive coverage on the job site.
Thanks to the Comansa modular system, this crane boasts a wide range of jib lengths, available at intervals of 4 or 6 metres, allowing for customizable configurations to suit various project requirements.
Similar to other Comansa flat-top cranes, the 21CM335 is equipped with a double trolley system featuring automatic reeving switchover. This enables the operator to make the most productive choice based on the specific situation. When the crane needs to handle its maximum load, it operates with the double trolley. For situations demanding the maximum jib-end load, the crane functions with only the front trolley and at maximum speed.
To optimize rental fleet management and minimize structural investments, this crane shares jib parts with the 21CM450 and 21CM550 models within the 2100 Series.
The Comansa panoramic cab comes as standard equipment in this model, which is exclusively offered in Asia, Oceania, Africa, the Middle East, and South America, ensuring a comprehensive and comfortable operating experience for users in these regions.

Among its capabilities, Hera Engineering can claim a high expertise in construction and temporary works engineering, and particularly for tower cranes design and verification. We were recently appointed for the verification of series of tower crane structures for compliance with Australian Standard, which is a legal requirement for importing foreign tower cranes. Among the projects we have worked on, is the verification of a Comansa 21CM335-18t heavy duty trolley-jib crane, which required complex wind and dynamic loads calculations and a detailed structural analysis model of the crane structure.
