Reconstruction and modernization of cranes from "Gutman Crane" Company

The equipment installed at the enterprise, over time, ceases to fully cope with the tasks. However, replacing worn-out equipment may not always be an economically viable solution. In most cases, the problem will be eliminated by the reconstruction and modernization of cranes. These operations will extend the life of the equipment, reduce energy costs and increase the lifting capacity of the crane.

Crane modernization

Modernization of the electrical equipment of cranes is carried out in accordance with the project, which is drawn up by specialized organizations. Modernization of overhead cranes and modernization of gantry cranes may be necessary in such cases:

• the need for increased load capacity and lift height, as well as the need for other types of upgrades that can redistribute loads and improve safety;
• the need to change the drive mechanism of the crane. Modernization of a gantry crane, as a rule, involves replacing the relay-contactor control system with frequency converters, which provide smooth descent and noise reduction during operation, and also prevent the load from swinging during lifting.

Crane reconstruction

Repair-reconstruction of cranes involves a set of works to change the main parameters of the crane. For example, the reconstruction of load-lifting cranes may be accompanied by the installation of a load-handling device not provided by the manufacturer of lifting equipment.

Reconstruction of overhead cranes may include the following works: changes in the control method (for example, installation of a remote control system), adding the function of technological or commercial weighing on the crane, etc.

Please note that in the process of drafting the project, it is necessary to take into account the actual state of the equipment: corrosion of metal parts, damage, wear, etc.

Modernization of cranes, in which the control of the crane from the cab is transferred to control from the floor, must be agreed with the technical supervision authorities, and the access of workers to such a crane must be carried out in a strictly established manner. At the same time, heavy duty hook cranes do not need a permit to be converted to grapple or magnetic washer operation. The owner can carry out this type of reconstruction independently, reflecting it in the technical passport of the crane.

Our specialists perform all the necessary calculations and carry out high-quality modernization of cranes at enterprises for bridge, gantry and other types of crane equipment. We will help you choose the most suitable option for your business.
