3.1 Working cycle
This PCT1800 AC Electric Portable Capstan Pulling/Lifting Winch
TM is designed for intermittent
use. The engine manufacturer recommends an engine duty cycle of 25%. So, to get a maximum
lifetime out of the engine, it should only be used for fifteen (15) minutes period every hour. This
data varies depending on the loads pulled or lifted. Light loads can be lifted or pulled
continuously without affecting the life of the engine. Continuous pulls are however less
damageable for the motor than frequents stop and go.

SUITABILITY.
DO NOT USE 3-STRAND POLYPROPYLENE YELLOW ROPE!

Polypropylene and polyethylene ropes are dangerous for winching because of their great
elasticity and low melt point.

Make sure the rope is not damaged and that it offers an adequate resistance to pull the
load.
STRETCH EQUALS DANGER!

A stretched rope can recoil and cause serious burns as the rope leaves your hand.

All ropes stretch: a longer one more than a shorter one. The more you pull, the more it
stretches.

A stretched rope can also move the load in an unpredictable or dangerous way.

A stretched rope can recoil and bring your hand towards the winch causing severe
injuries. NEVER WRAP THE ROPE AROUND YOUR HAND.
ALWAYS WEAR GLOVES.
3.2.2 Rope maintenance
The rope and its ends should be inspected regularly to detect wear. Please
refer to CI 2001 Document - FIBER ROPE INSPECTION AND RETIREMENT CRITERIA from
the Cordage Institute available at www.ropecord.com for the procedure and criteria of scrapping
the rope.
You will find a chart located at the end of this manual to better help you register your
observations.
