To learn more about some of Caldwell’s interesting and unique lifter builds, visit our blog: https://www.caldwellinc.com/blog How long does it take to build a custom lifter? Without all of the specifications for your build, there is no good way to give you an answer on how long it takes. The most important step in the process Is, in fact, gathering all of the information from you that not only details what the intended load is, but also includes things like what happens in the steps before and after the lift, if we’ve ever built something similar in the past, what your deadlines are, what raw materials or components are available, how long it takes for the approval processes or revisions along the way, and so much more. The thing we can say with confidence is that we’d put our team of technical service representatives and on-site engineers up against any in the lifting business. Caldwell has been producing custom lifters for most of our 70 years and are the most-trusted resource for the lifting and rigging industry. Maybe you just need some length added to a standard lifting beam, or maybe you need us to build a transport carriage for a space ship, or maybe you need to lift an elephant … we’ve done it all and can’t wait to help you find a solution to your lifting problem. WARRANTY INFO What is Caldwell’s warranty policy? The warranty period for new product fabrications & installations is two (2) years from the date of delivery of the new product, which is double the industry average.

The ultimate pad capacity (UPC) shall be determined by the following formulas: Inch-Pound Method UPC = A (Hg / 2) where: A = effective area of the vacuum pad, expressed in square inches, enclosed between the pad and the material when the pad is fully compressed against the material surface to be lifted. Hg = system vacuum expressed in inches of mercury. Reductions for altitude, efficiency, consistency, and wear of vacuum source shall be considered. 2 = constant divisor. Electrical equipment and wiring shall comply with ANSI / NFPA 70 and ASME BTH-1 The UPC / rated load shall be a minimum of 2 to 1 for horizontal surface lifts The UPC / rated load shall be a minimum of 4 to 1 for vertical surface lifts These requirements are for clean, flat, dry, non-porous material. Contact the manufacturer for other surface types There shall be a vacuum reserve of sufficient size to prevent the vacuum level from decreasing more than 10% in 4 minutes without power to the vacuum generator Vacuum lifting devices shall be designed according to ASME BTH-1, Design Category B, taking into consideration the load, including the weight of the lifting device. The Service Class of the lifter shall be determined by the number of load cycles required All welding shall comply with ANSI / AWS D14.1 and ASME BTH-1 Marking: The rated capacity, maximum width, maximum length, and minimum thickness of the load shall be marked on the lifting device. If the vacuum lifting device has shutoff valves on individual pads or groups of pads, the rated load of each pad shall also be marked. The rated capacity of pads or groups of pads with isolation values shall be labeled individually Caldwell vacuum lifting devices shall be marked with the following information: Manufacturer’s name and address Model number Serial number Vacuum lifting device weight Electrical power requirements (when applicable) Pressure and volume of compressed air (when applicable) Rated load ASME BTH-1 Design Category ASME BTH-1 Service Class Product Safety Labels Where possible, all lifting devices shall have labels that include the appropriate signal word, according to ANSI Z535, including the proper cautionary notice to operators against improper use. When it is not possible to include the above, a label shall be affixed, referring user to the manufacturer’s instruction manual for product safety information. Isolation valves shall be marked to show proper operating positions. Load Test: Before use, a new, altered, modified or repaired vacuum lifting device should be load tested and inspected. Contact the manufacturer for information regarding the appropriate test load for the lifting device. Definitions: Should = a recommended procedure; Shall = a required procedure.
