GrabiQ – A Simpler, Smarter, Chain Sling System

 Download Gunnebo / Johnson Catalog

GrabiQ is an exciting new family of alloy chain sling components. Instead of the old “one component does one job” fitting, GrabiQ combines in a single component up to three separate functions replacing up to seven different fittings.

Figure 1 features a GrabiQ Master Grab Dual, which serves as the master link, connecting links for two legs of chain, and shortening hooks for each leg, all in one fitting.

Using traditional fittings to construct the same sling (figure 2) would require 7 top-of-the-sling components, instead of just one. 

Some of the new GrabiQ fittings are equally well suited for use as top assembly connectors or hooks at the bottom of a sling, adding even more flexibility for riggers.

A four-leg fully adjustable GrabiQ sling will never have more than 3 total top fittings (figure 3) while the same sling from traditional fittings requires 15 top-of-the-sling-components (figure 4).

 

The GrabiQ Advantages:

  • Every Leg Adjustable

  • More Strength – Grade 100

  • Less Weight

  • More Rigging Flexibility

  • Less Head Room Required

  • Fewer Top Fittings

  • Quicker Inspections

Chain Slings - Technical & Usage Information

Basic Inspection Criteria For Chain Slings

  1. Daily check for visible faults in links or hooks.
  2. At least twice a year:
    • Clean slings prior to inspection.
    • Hang the chain sling up or stretch the sling out on a level floor. Remove all twists. Measure the length. Discard if sling has been stretched.
    • Make a link-by-link inspection.
  3. Once a year:
    • We recommend to have the chain slings proof tested to twice the WLL and re-certified.
    • It is important to inspect chain slings and to keep a record of individual chain inspections.
  4. Remove from service if you detect:
    • 10% or more wear on individual links or contact points on any hardware
    • 5% elongation of individual chain links
    • chain link wear exceeding the values given in table below.

Lifting Practices Checklist:

  • Find out load weight before lifting.
  • Lower working load limit if there may be severe impact.
  • Balance the load to avoid over-stress on one sling leg or the load slipping free.
  • Pad sharp corners to prevent bending links.
  • Replace broken safety latches.
  • Reduce the chain capacity when using chain in temperatures above 400°F.
  • Keep hands and fingers from between load and chain.
  • Store chain slings on racks in designated areas.
  • Do Not Jerk the load when lifting or lowering the sling. This increases the actual stress on the sling.
  • Do Not Drag the sling.
  • Do Not Splice the sling by inserting a bolt between two links.
  • Do Not Try to Repair the sling unless you are properly trained. Use only original spare parts.
  • Do Not SHORTEN the sling with knots.
  • Do Not Force a hook over a link.
  • Do Not Use homemade connections. Use only attachments designed for the chain.

Remove From Service If You Detect:

 Chain Slings

  • Specifically recommended for overhead lifting.
  • Grade 100 Chain is 25% Stronger than Grade 80, enables you to preform same lifts with lighter weight chain
  • Proof Tested, Alloy steel, Heat Treated
  • Should Not Be Plated or Galvanized
  • C10 or V8 Hallmarking approx every 12"
  • Design Factor 4:1

How to Order Chain Slings

Warning: Never Exceed Working Load Limit!

Type of Sling: Select the proper type of attachments from the illustrations in this catalogue.

Size: Determine the working load limit required, then check our catalogue for the size of chain needed.

Reach: Decide upon the overall length (bearing point of master link to bearing point of fitting).

Angle to the Load: Estimate the proper angle between the leg of the sling and the load during operation.

Sling Code: Use the following table to identify the sling you want.

First Symbol (Sling Type)

S = Single Leg
D = Double Leg
T = Triple Leg
Q = Quadruple Leg
*Add an “A” to the beginning for an adjustable chain sling

Second Symbol (Master Link)

O = Oblong Master Link (Recommended)
P = Pear Shaped Master Link (Upon Request Only)
*Replace master link symbol with hook symbol for single leg slings

Third Symbol (Hook Type)

S = Sling Hook
G = Grab Hook
F = Foundry Hook
SH = Self Locking Hook (specify type)
H = Hammerlock

D.O.S (Size) X (Reach)

NOTE: All chain slings are made to customer specifications and are therefore a non-returnable item. Please ensure all sizes and measurements are correct before ordering.

NOTE: The Pear Shaped Master Link and the Master Ring are not recommended but are available on request. Due to its geometry you must use a larger material diameter Master Ring when selecting a sling with a Master Ring as opposed to one with an Oblong or Pear Shaped Master Link.
