Personal injury or death can result from improper lifting or blocking. When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component. Approximate weights of the components are shown. Clean all surfaces where parts are to be installed.

Show/hide table

To avoid injury do not stand on or between implement and machine while operating lift control.

Introduction

The 142-6893 Adjustable Lifting Bracket Group is a "C"-style lifting device. The lifting bracket is used to remove and install heavy parts and assemblies for a wide variety of applications.

The following features provide maximum versatility:

• Internal threaded rods adjust extension arms to achieve center of gravity.

• Asymmetrical, adjustable lifting bracket can be oriented with either arm in the upright position.

• Additional adapters increase versatility and eliminate the need for multiple lifting brackets.

NOTICE
Failure to follow the instructions or heed the warnings below could result in injury or death. Verify that the load to be lifted does not exceed the specified capacity. Measure the length of extension at A and B, and match with the chart. Always use the lower of the two capacities. Always adjust the arms to the shortest usable length. Refer to the service manual for specific applications. Do not adjust under load. Inspect the condition of the lifting bracket group prior to use. Lubricate as necessary.

Optional Adapters

Optional adapters can be used to make this tooling more versatile.

Note: For more details on optional adapters, check the referred documents in section ""References" ".

Hardware used to attach adapter plates and bracket assemblies must meet or exceed 10.9 Metric or Grade 8 (English) specifications. Always use hardened flat washers, and tighten all hardware to the correct torque value for the fastener size.
