Specifications:
The document outlines the specifications for different models of cranes, specifically the KBK-I, KBK-II, and KBK-III. Each model has varying load capacities, bending radii, and bending angles. The load capacities range from 500kg to 2000kg, with bending radii starting from 1000mm and bending angles between 10° to 90°.

Procedures:
The document provides details on the maximum hanger spacing for single and double girder systems, rotation radius, and lifting height. It also specifies the control methods, which include pendent or remote control, and the rotation methods, which can be manual or motorized.

Performance Parameters:
Lifting speed is specified as 0.4 to 0.8 m/min, while trolley speed varies with single and double speed options. Rotation speeds are also provided, with angles of 180°, 270°, and 360°.

Recommendations:
The document suggests using specific models based on the required load capacity and operational needs. It emphasizes the importance of selecting the appropriate control and rotation methods to ensure efficient operation.

Key Data from Tables:
The tables provide a detailed comparison of the different crane models, highlighting their load capacities, bending radii, and operational speeds. This information is crucial for selecting the right crane model for specific industrial applications.
