Page 3: Introduction
Thank you for choosing a Gorbel® Retrofit II to solve your material handling needs. The innovative design and heavy-duty construction of a Retrofit II added to an existing jib will provide a superior quality product that will offer years of long term value. All Gorbel® cranes are pre-engineered for powered hoist operation. The hoist weight allowance is 15% of the crane capacity (for example, a crane rated for 1000 pounds allows for a 1000-pound live load plus 150 pounds for the weight of the hoist). -

(VARIABLE FREQUENCY CONTROL DRIVE) JIB DRIVE CONTROLLER The drive controller for the jib drive is pre-programmed at Gorbel for single speed, two speed, or three speed operation. For troubleshooting and general information, a brief summary of how the drive controller is designed to be used is included below. No additional programming is required. - Page 7 DRIVE CONTROLLER PROGRAMMING Gorbel pre-programs a number of parameters in the drive controller prior to shipment. The remaining parameters are left at the factory default settings. All parameters are stored on the EPM module. These parameters are as follows:...

Page 8: Step 4 - Limit Switch Installation
STEP 4 - LIMIT SWITCH INSTALLATION If applicable, install limit switches per the following instructions and diagram 4A on page 8. The limit switches are designed to shut off the power to the rotation drive motor in a clockwise or counterclockwise direction and are not intended to serve as a spotting function. - Page 9 STEP 4 - LIMIT SWITCH INSTALLATION (CONTINUED) RAMP INSTALLATION: Two rotation limits can be established, one in the clockwise direction and one in the counter- clockwise direction. The lower switch will be the clockwise rotation limit switch and the upper switch will be the counterclockwise rotation limit switch.
- Page 10 STEP 4 - LIMIT SWITCH INSTALLATION (CONTINUED) Over Travel Adjustment Instructions: All cranes will experience some over travel, after power to the drive is shut off, due to inertia of the load acquired during rotation. The amount of over travel is dependent on the application and the size of the jib crane.

Appendix A: Securex Friction Torque Limiter Type C & T Installation & Maintenance Instructions (Size 30 Thru 280) • Read and follow all instructions carefully. • Disconnect and lock-out power before installation and maintenance. Working on or near energized equipment can result in severe injury or death. •... - Page 17 RUNNING-IN Torque Limiters should be run-in for the most consistent results. To run-in, adjust the Torque Limiter to 25% of the maximum single spring capacity and slip the center member approximately 50 RPM for approximately 4 minutes. TORQUE SETTING PROCEDURES Type 30 ÷...
- Page 18 Type 95 ÷ 170: slip torque is preset by adjustment of 4 or more screws on the nut (B), providing axial load to the disk spring. This system makes the adjustment easy. Apply springs load by loosening the adjusting bolts in approximately 60 degrees steps until no slip is observed under maximum load conditions in normal running mode.
- Page 19 TORQUE CHECKING To check the Torque Limiter for the required slip torque, mount the Torque Limiter on a stub shaft and fasten in a bench vise. Wrap the center member (if a sprocket) with a chain and load the chain with weights until the center member rotates. If the center member is a plate, attach a chain or cable to the center member.
