What you need to know to properly size a vacuum lifter

Engineered Lifting Systems & Equipment (ELS) prides itself on offering a wide selection of standard and custom overhead material lifting systems. Its comprehensive portfolio includes真空的生活ters, which the company can size to meet the needs of each specific application.

所需的关键细节

In order for ELS to size a vacuum lifter, particular variables need to be confirmed. For example, if a vacuum lifter is needed to handle sheet metal, the following information is required:

• Maximum sheet size:What is the maximum length, width and thickness of the sheets the lifter will be handling? This helps determine the lifter’s overall capacity.
• Minimum sheet thickness:What is the minimum thickness of the sheet the lifter will be handling? This helps determine the number of vacuum cups required to reduce deflection. A two-inch deflection is the normal design maximum for sheet steel.
• Power sources:What power sources are available or desired? ELS typically suggests a self‐contained mechanical vacuum generator that requires no outside power source and can be lifted with any overhead crane/hoist or forklift.
• Sheet configuration:Are the sheets always lying flat or do they need to stand up?
• Sheet appearance:Are the sheets solid, or are there holes or cutouts in them?
• Work space:Are there existing overhead lifting devices that cover the work area? If there are not, careful consideration must be taken to ensure adequate floor coverage without creating interferences or blocking egress routes or light curtains.
• Other operations:Are there other operations in the work cell that would require the use of a lifting device? This would indicate whether the vacuum lifter would need to be quickly and easily swapped out with other equipment.
• Additional considerations:Two-speed hoists should be used whenever possible to prevent “jerking” the load. Any air resistance can pry the sheet metal off of the vacuum cups. Also, proper elevations are key to ensuring that the operator’s hands are in the optimal ergonomic working ranges.
