# Manual Chain Hoists: Capacity Selection, Inspection and Safe Operation Manual chain hoists are fundamental lifting devices used extensively in industrial, port, and offshore environments to move heavy loads with precision using human power. These mechanical units rely on the principle of friction between a rotating drum and a chain loop to generate the necessary torque for lifting. Unlike electric models, they require no external power source, making them indispensable in remote locations or areas where electrical supply is unreliable, such as deep-water offshore rigs or congested port terminals. Their reliability stems from simple mechanical design, yet this simplicity demands rigorous adherence to operational protocols to prevent catastrophic failure. For CML SARL's industrial and port customers across Cameroon and Central Africa, selecting the correct manual chain hoist is critical for project efficiency and personnel safety. The device must be matched precisely to the specific load weight and environmental conditions, ensuring that the Working Load Limit (WLL) defined by the manufacturer is never exceeded. Proper maintenance and inspection regimes are equally vital, as wear on pins, bushings, or chain links can compromise structural integrity over time. This guide outlines the technical considerations required for safe deployment, emphasizing that all operations must align with the specific documentation provided by the equipment manufacturer and local regulatory fram...
