Linden Comansa, Pineville, N.C., introduced two new models of luffing-jib cranes, which will be available by the end of April. These new cranes, LCL 310 and LCL 280, together with the LCL 190, form the new family of luffing-jib cranes which will be completed this summer with the launch of a fourth model, LCL 165.
The design and development of the series has been based in Linden Comansa’s modular system. Most jib sections are interchangeable between the cranes of the series. The tower sections are not only interchangeable with the cranes of the same series, but with the models of other series of flat-top cranes as well.
The cranes are designed with the hoist mechanism at the front under the jib and near the cabin. The luffing mechanism has an emergency second brake, and the electrical control cabinet is placed on the counterjib. This allows reduction of the installation weights and the slewing radius of the counter-jib. Hoisting and luffing cables come preinstalled from the factory for faster installation of the crane.
Both cranes are equipped with features from the LCL 190. This includes electronic coordination between the luffing and hoisting mechanisms, which allows the operator to move the load horizontally when operating only the luffing movement. The hydraulic push and retention system; the travel control of the luffing movement; and an anti-loosening system for the luffing cable tension are also featured on the LCL 190.
Each of the two new cranes comes in three versions depending on its maximum load of 12, 18 or 24 tonnes. These luffers can be erected with the already existing 6-meter wide or an 8-meter wide cross base. This 8-meter base can be used in other models of cranes to increase heights up to 30 percent. This base can now also be used on models 21 LC 750 and LCL 500, which, until now, could only be erected with the 10-meter base.
Linden Comansa’s new Panoramic XL cabin will be available as an option in the LCL series of luffers and LC2100 series of tower cranes. It has the same features of the standard Panoramic cabin such as acoustic insulation and full view of the load and work area, but is half a meter longer. It includes a small refrigerator, an air handling unit, and room for another small appliance.
