Dear Prospective Proofloading Inc. Clients:

 

Proofloading Inc. offers to provide a quote to ASME B.30.20 and our engineered specifications or other requirement to include:

·         Engineering

·         Fabrication (mill certificates) if required

·         Blast and Paint

·         Vinyl load ratings and Engraved ID plate

 

(The following definitions have been included to assist you in determining which style of Lifting Device best suits your needs.)

 

Lifting Device Definitions

 

Lift Beam

·         Single lug attachment on top of device usually directly to crane.  Very good bar for balanced loads and limited headroom.

Spreader Bar

·         Dual attachment lugs on top of bar usually requiring slings to make connection to crane.  Very stable lifting platform requiring headroom for rigging.

Adjustable Spreader Bar

·         Either multiple available attachment lugs on top of bar to be used in pairs or multiple available connection lugs on bottom to accommodate varying dimensions of loads.

·         Spreader bar is fabricated from two or three sections to accommodate varying lengths and dimensions of lifts.  Ex: Spreader bar may have a capacity of 10 tons and be adjustable in length from 10' – 16'.

 

*****************************************************************************************

 

** The following information is required to engineer, fabricate and certify “Below The Hook Lifting Devices” such as: Spreader Bars or Lift Beams as per Proofloading Inc guidelines. ** 

 

Fabricate a new Spreader Bar or Lift Beam for designed or general purpose lifting:

·         Do you require a Spreader Bar or Lift beam?

·         What are you lifting?

·         General arrangement drawing of the lift(s) showing center of gravities for designed lifts

·         Lift lug details from the skid(s) or lift

·         Shipping weight and dimensions of lift

·         Length and required capacity of the lift device

·         Picker’s reach and capacity for the lift

·         What province(s) or country are you planning on using the Lift Device in?

·         Does the lifting device have to meet a customer’s specific code such as ASME B.30.20, DNV (Det Norske Veritas) or ABS (American Bureau of Shipping)?

·         Upon receiving your order and PO# to commence work, it is generally about a week to ten days to create an engineered drawing.  The completed lift device is generally 2-3 weeks to delivery.  Every order received is treated with equal importance and diligence.  Some aspects of orders can be fast tracked at a premium over quoted costs, such as weekend work to accommodate short delivery schedules.  These must be authorized before work commences.

 

Load Test your supplied fabricated Lifting Device

 

·         Customer must supply an engineers stamped and signed drawing to insure project is approved and not subject to further changes.  If an engineers drawing does not exist or is not available we can reverse engineer the device and certify it.

·         Load test, including Certificate of Test

§         Vinyl load ratings and Engraved ID plate

 

We trust this explanation assists you in understanding our minimum requirements.  Please call us to discuss at your earliest convenience should you require further assistance.
