A plain trolley, also known as a push trolley or manual trolley, is a lifting and rigging device used to move horizontally along a beam or track in various industrial and material handling applications. It is typically used in conjunction with hoists, chain blocks, or other lifting equipment to transport loads horizontally along an overhead beam or runway. Plain trolleys are commonly used in manufacturing, construction, warehouses, and other settings where materials or equipment need to be moved within a workspace.
EN 13157 is a European standard that specifies safety requirements for manually operated plain trolleys and hand-operated trolley hoists used in industrial and commercial applications. These devices are commonly used for lifting and transporting loads along a horizontal beam or track, such as an I-beam or overhead crane runway. The standard sets out requirements to ensure the safe operation of plain trolleys and hand-operated trolley hoists.
Here are some key points related to plain trolleys and EN 13157:
- Scope: EN 13157 specifies safety and performance requirements for manually operated plain trolleys and hand-operated trolley hoists intended for use with various lifting equipment, such as chain hoists and wire rope hoists.
- Design and Construction: The standard outlines design and construction requirements for plain trolleys, including materials used, load-bearing components, and safety features. It covers aspects like trolley wheels, load hooks, and suspension.
- Load Capacity: Plain trolleys have specified load capacities, and these should not be exceeded to ensure safe operation. The standard provides guidance on how load capacities should be determined and marked on the equipment.
- Testing and Certification: Manufacturers of plain trolleys and hand-operated trolley hoists must conduct testing to ensure compliance with the standard's safety requirements. Equipment that meets these requirements can be certified accordingly.
- Safety Features: EN 13157 includes requirements for safety features such as brakes, load-limiting devices, and emergency stop controls to enhance the safety of these lifting devices.
- Instructions for Use: Manufacturers are required to provide clear and comprehensive instructions for the installation, operation, and maintenance of plain trolleys and hand-operated trolley hoists.
- Inspection and Maintenance: Users of these lifting devices should perform regular inspections and maintenance to ensure that they remain in safe working condition.
- Training: Operators and users should be adequately trained in the safe operation of plain trolleys and hand-operated trolley hoists.
It's important to note that compliance with EN 13157 is essential for ensuring the safe operation of plain trolleys and hand-operated trolley hoists in Europe. Users and operators should also adhere to relevant local regulations and safety standards to maintain safe working environments.
