1. WINCH/PULLEY LOCATION. Placements of the winch and hoist pulley are critical to ensure the proper and safe folding

operation of the backstop. Refer to the backstop installation drawing(s) provided with this project for all dimensional data

parameters.

A. When the unit is in the "UP" (stored) position, the cable tie-off at the mast must be directly below the pulley sheave. Failure

to do so will place additional lateral loads on the superstructure. See Illustration 1.

B. The pulley is to be located on the

exact centerline of the backstop

mast as indicated on the backstop

installation drawings. Refer to

Pages 26 and 27 in the Basketball

Backstop Installation Manual for

complete cable tie-off details.

C. To avoid excessive wear on the

pulley sheave and chafing of the

cable against previous wraps on

the drum, the sheave is ideally

located on the centerline of the

drum. HOWEVER, if the cable

does not wind evenly on the drum,

the winch may be offset slightly

from the sheave centerline to

obtain an even wrap on the drum.

See Illustration 2.

2. SECURING CABLE TO THE WINCH DRUM. Route plain end of cable through hole in the

winch drum and secure with set screw. Note that cable must be taped before cutting to prevent the

cable end from fraying. Be sure to route cable in the UNDERWIND direction as detailed in

Illustration 3. THERE MUST BE A MINIMUM OF THREE (3) WRAPS OF CABLE ON

THE DRUM WITH THE BACKSTOP IN THE "DOWN" POSITION.

Do you have a question about the Porter 713220HT and is the answer not in the manual?

This document provides installation, adjustment, troubleshooting, and field evaluation instructions for Porter Electric Winches, specifically the No. 713220HT model, and generally for 712 and 713 series winches. These winches are designed for use with basketball backstops, overhead volleyball systems, and divider curtains, with their use on other products expressly prohibited.

Function Description

The Porter Electric Winch is designed to raise and lower athletic equipment such as basketball backstops. It operates by winding and unwinding a cable around a drum, controlled by a motor and a rotary counting limit switch system. The limit switch system ensures the equipment stops at precise "UP" (stored) and "DOWN" (playing) positions, preventing damage to the equipment or overhead structures and ensuring proper cable slack.

Important Technical Specifications

Cable Type: 1/4" Galvanized Aircraft Cable with a 7000 lb. minimum breaking strength.
Cable Wraps: A minimum of three wraps of cable must remain on the drum when the backstop is in the "DOWN" position.
Cable Winding Direction: Cable must be routed in the "UNDERWIND" direction.
Limit Switch Type: Rotary Counting Limit Switch.
Motor Connections: Uses specific wiring for motor and power cord connections (Red, Black, Blue for motor; White, Pink, Green for power cord).
Safety Clearance: A minimum of 8" clearance to any overhead structure, ceiling, lights, or other equipment is required when the backstop is in the desired storage position.
Hardware Torque: All attachment hardware should be tightened to 14-18 ft-lbs (168-216 in-lbs) of torque.

Usage Features

Winch/Pulley Location: Critical for proper and safe folding operation. The cable tie-off at the mast must be directly below the pulley sheave when the unit is in the "UP" position to avoid lateral loads. The pulley should be on the exact centerline of the backstop mast. Slight offset of the winch from the sheave centerline may be necessary to achieve an even cable wrap on the drum.
Cable Securing: The plain end of the cable is routed through a hole in the winch drum and secured with a set screw. Taping the cable end before cutting is recommended to prevent fraying.
Limit Switch Settings: Both upper and lower limits must be set carefully.
- Upper Limit: Prevents contact with overhead structures.
- Lower Limit: Prevents excessive slack in the cable, which can lead to uneven wraps and "exceeding" the upper limit. A slight amount of slack is mandatory when the backstop is in the down position. To properly set slack, allow approximately one second of delay after the backstop fully seats before the down limit switch shuts off the down cycle.
- Adjustment Process: Involves depressing the pressure lock guide plate and turning traveling nuts to engage the limit switches. The tab on the pressure lock guide plate must be seated in a notch on both traveling nuts.
- Securing Adjustments: After adjustments, two #8 x 1/4" self-tapping screws and lock washers are installed into the bottom of the limit switch box to prevent future movement of the pressure lock guide plate.
Operation: The unit should be operated through three complete up-down cycles after initial setup and adjustments to ensure the cable is properly seated on the drum and to fine-tune limit switches.
Control: Operation requires a Porter key switch or controller. Substitution with non-Porter Powr-Touch systems voids warranties and renders operation unsafe. The key switch or controller must be mounted where the operator has a full view of the equipment being controlled.

Maintenance Features

Regular Checks:
- Confirm cable is wrapped in the proper direction and has a minimum of three wraps on the drum.
- Check for proper cable length, especially for units with optional cable retractor reels or flex-cords.
- Ensure hardware securing micro switches is fully tightened.
- Verify that both traveling nuts are properly seated on the tab of the pressure lock guide plate after adjustments.
- Check belt tension and replace if worn or adjust if loose.
- Inspect pulleys for keys, tightness of set screws, and alignment. Replace warped or damaged pulleys.
- Check the drum for rotation and engagement with the gearbox.
- Verify limit nuts are secured with the spring plate and screws.
- Inspect the limit drive assembly (gears) for damage and engagement.
- Check the limit rod for integrity and snugness.
- Tighten all attachment hardware to specified torque.
- Check for foreign objects in the motor housing.
Troubleshooting Guide: Provides solutions for common symptoms such as:
- Winch not running (check plug, power, wire connections, limit settings).
- Motor running but winch not lifting (check belt tension, limit settings, pulleys, drum, gearbox engagement).
- Limit set location seems to move (verify limit nuts, limit drive assembly, limit rod).
- Winch is noisy (check belt/pulley alignment, limit box lid, attachment hardware, foreign objects).
- Winch running backwards (check motor wiring to limit switches).
Field Evaluation Checklist: A comprehensive checklist to be completed for any warranty claim or product return, ensuring all critical components and settings are verified. This includes checks for power, plug engagement, connections, limit nut positions, limit drive rod condition, belt tension, pulley alignment, set screw tightness, attachment bolts, and foreign objects.
