    It is interesting to find out a few things from a professional in the field. We have a relationship with a reputable heavy duty wrecker company. They put us in touch with their equipment supplier who inspected our rig, asked how we wanted to use it and recommended supplies. The first thing he recommended we replace was the brand new cable and hook. He pointed out the cheap quality and the poor splice and lack of a swivel on the hook. Aside from actually understanding the winch operation we got quality equipment at a price suitable for tow guys and not with the magic "rescue" price hike.

    You would be surprised to learn how few are knowledgable about winching operations related to rescue.

    You would also be surprised how little people know about winching operations in general. For example, the line pull rating of the winch is based on the first layer of wire rope on the drum (not counting the 3-5 safety wraps). Each additional layer of wire rope added to the drum decreases the line pull capacity of the winch. For example, a towing operator has an 8,000 lb. winch with 100 feet of 3/8" wire rope. If he uses 50 feet of the wire rope, it leaves just two layers of wire rope on the winch drum making the line pull capacity 6,700 lbs. However if he uses only 15 feet of wire rope it leaves 3 layers of wire rope on the drum, making the line pull capacity just 5,000 lbs. For this reason, you may see towing operators who only have 25í to 50í of line length so that they can have the rated pulling strength even with very little cable pulled.

    Exactly, as the winch drum collects the wire rope the pulling capability will decrease. Also, I'd suggest investigating the actual breaking strength of the wire rope on your winch AND ask the manufacturer what the WLL of the wire rope is. You may be surprised.

    That's true if the Tow operator is using a center driven winch.However if the operator is using an older Holmes winch on a 750,850,1601 or 1701 the rules change.These are PERIMETER driven winches and maintain upwards of 80% capacity even with a full drum.One of the reasons they are a favorite still with established companies that have been around a while and that do a lot of heavy winching.These units have lineage dating back to the 50's yet modern equipment is still compared to them,IE pulls twice as much as a 750,pulls the same as a 750.In it's time the 750 Holmes set the "benchmark"on performance in heavy duty towing.And there are still a great many doing service across the country.Todays new planetary heavy winches are fast and powerful.But the old 750 still has a place when you need pure brute winching power.

    What would really be interesting would be a Poll for those who do have a vehicle with a winch. I'd ask the question, "How often do you train with it?" The answer for the majority of FDs, I believe, would either be 'Never Have' or 'Saw it used once but can't remember when that was'.

    I think we'd all be shocked at the small percentage of firefighters within our department who could safely and efficiently operate that tool at an emergency incident.

    Do your own poll. Are you a Never or Can't Remember When department?

    I'll be the first to admit I know very very little about winching operations. I would definitely like to get a class for our people.

    There are resources for training regarding winches, rigging, snatch blocks, etc. If you're seriously interested, please send me a direct email resqman@asheboro.com.

    Please send any questions/comments you may have.

    I have a winch on my personal vehicle and we're vollie so there's a good chance I may respond in that. I always carry at least 1 snatch block. As far as dept. vehicles go we don't have a winch on any of those.

    I'm new on the dept. so I need to check with the chief to see if it's cool to use it or not though.

    Ok.. the new rig has arrived. It has receivers on all four sides for the 5000 pound winch. Looks like we will need some snatch blockes. I know one of our Captains has sent an e-mail to BigRig to see what kind of information he can give us so that we can start training on the thing.

    Question

    Ok Metal Medic, send me a direct email at resqman@asheboro.com and include any specififc questions you may have.

    In order to select snatch blocks, one should know:

    size of wire rope
    WLL of the wire rope

    Actually snatch blocks can serve a valuable purpose, if selected and used correctly.
