Instruction Manual

GENERAL
This manual is intended to provide information for the safe use of the Contrx Portable Jib Crane. Anyone using or maintaining this product should be familiar with the information in this manual. The equipment described in this manual is not designed for lifting, supporting, or moving people.

ASSEMBLY
Before using this jib for the first time, refer to the drawing attached.
Assemble according to following instructions:

1. Locate the base pad on a horizontal surface of sufficient strength and rigidity to support the weight of the assembled crane. The crane weight is given on the specification sheet attached.

2. Clean any debris from the tapped holes in the top of the base pad. Locate the jib column in an upright position on the base pad, with the jib base plate holes aligned with the base pad holes.

3. Insert the eight special anchor bolts through the jib base plate and into the base pad holes. Tighten each anchor bolt to 100 foot-pounds torque.

4. Attach the boom assembly to the upper pipe assembly using the boom mounting hardware provided.

5. Position the main bearing cone on the upper bearing pin. Coat the bearing cone with heavy bearing grease.

6. Lower the upper pipe assembly and attached boom assembly onto the jib column top. The main bearing cone must seat inside the main bearing cup.

7. After mounting a trolley (not included), attach the trolley end stops with the hardware provided.
