COMMON OVERHEAD APPLICATIONS

Using Two Chicago

Grips in Tandem

For applications where the maximum load exceeds the safe load of an individual grip, or the cable is at risk of deformation, it is

recommended to use two Chicago Grips in tandem. Using two grips in tandem divides the weight load between both grips, allowing

for an effective work load increase of 1.5 times the safe load of each individual grip.

For example, two Klein Tools 1628-40 Chicago Grips, each with a maximum safe load of 25,000 lbs. (11,340 kg) individually,

have a combined working safe load of 37,500 lbs. (17,009 kg).

In some transmission applications—commonly using the 1628-30, 1628-40 or 1628-50 series Chicago Grips—there is a risk of cable

deformation under high tensions. To avoid this risk, Klein Tools recommends using two grips in tandem if:

• ACSR or AAC conductors – the load is expected to exceed the lesser of 12,500 lbs. (5,670 kg) or

40% of the conductor tensile strength.

• ACSS conductors—the load is expected to exceed the lesser of 10,000 lbs. (4,536 kg) or 40% of the

conductor tensile strength.

1. Place each grip on the same conductor, approximately five feet apart.

2. Connect a pulley block (leveling block) to the eye of each grip. This will maintain equal distribution of the weight

load between both grips.

3. Connect an anchored chain hoist of appropriate capacity to the block as shown in the image above.

4. Ratchet the chain hoist to the desired tension, as shown in the image below.
