Roofing Hoists (Tranzsporters ()) save the backbreaking work of manually moving heavy shingles, felt, plywood, solar panels, air conditioners and other materials to roof tops - and they transport materials *much* safer than climbing a ladder while carrying materials. They also cut the time of getting materials to a roof. They are especially valuable when working on a project by yourself and for locations unaccessible with heavy equipment. These hoist can also be easily customized to work as an elevator or dumb waiter to move boxes of paper files to upstairs storage or groceries into homes built on poles near the water. I have also used them to move furniture when it could not be carried up spiral stairs.

We have solved the problem of the high cost of commercial brands by designing a platform that can easily lift over 500 lbs. You can use any extension *aluminum* ladder to build your own *or* any Werner brand ladder (sold at Lowes and many hardware stores) to match our pre-built platforms.

You'll have a stronger product at half the price of any other new hoist on the market by using our plans and buying your own electric motor. Or buying our platform and putting it on your own Werner extension ladder.

The setup is lightweight and strong and will not rust. The motor and pulley connects to a ladder with U-bolts - without causing damage to a ladder you may want to use for other purposes when you are not using it for a hoist. It is built with wheels to reduce friction for smooth and even travel up and down the ladder. It locks onto the rails like a roller coaster and will not come off. The platform is designed at a 15 degree slant so that the materials will be level when the ladder is leaning against a building. The entire setup (with motor attached) weighs about 75 lbs. - making it easy for one man to setup and move.

After several years driving over the road I'm back at home where I have a shop and can build the platforms again. You now have the option of purchasing the platform to install on your own ladder or the plans to build one yourself... and you can pick up the entire setup if you live near Mobile Alabama.

The prices of ladders and hardware has gone up considerably in the past 5 years but I'm keeping the price to $300 and paying the shipping.

The plans are available for $55 (including shipping) and come on DVD divided into 5 videos about 20 minutes each. They play on a computer and can be paused, backed up and viewed like any videos on Youtube.

You can purchase the plans via PayPal by clicking the icon below. If you have a PayPal account it takes only one click. Make sure your shipping address on file at PayPal is correct. If you do not have a PayPal account they will process your credit card and I'll ship to the address you provide.

Harbor Freight sells the 880 lb. lift electric hoist (for about $100 - use their 20% off coupon) we have found it to be the best suited and most reasonably priced. (You can use the 440 lb hoist but it's not as easy to attach and price differnce is not much. Their 1300 lb hoist will not fit between the rungs of the ladder. These hoist lock automatically in ever position (when off) which is much safer than a hand brake - especially when lowering material. The controls are on a 6 ft cable. This makes it safer to use than the traditional designs because you aren't required to stand under the load that is being raised to operate the hoist. Also, electric hoists are much easier to relocate, setup, operate, they are much quieter and they don't require cranking or refueling or frequent maintenance like gas engines. There are no belts to wear out or replace either. It's also good to know that 'should' you wear it out, the cost of an electric motor is about 1/5 the cost of a gas motor. I've never worn one out but I *KNOW* that if you did you will have made so much money with it that you won't mind buying another one. (Tip: As with all hoist, winches and equipment that uses cables, keep the cable TIGHT on the spool so you don't create a "bird nest" that frey's the cable.) (Another important tip: since this hoist motor does not require cranking it's imperative you don't let kids have access. A simple press of the button could cause broken bones between the platform and ladder.)

Lowes has the 32 ft extension ladders - which makes a 16 ft hoist with the bottom section. They have two kinds - one is rated at 250 lbs and the other is rated at 225 lbs. The 225 is about $100 less and works just as well. If you go on eBay and buy a 10% discount coupon (for $1) it will pay the taxes.

Tips for assembly.

Build your own

Step by step video instructions are now available on DVD for $55 to build your own hoist for personals use. Just watch the video and follow the steps - It's easy!
The first section covers the parts that are needed including nuts and bolts - sizes and lengths - quantities.
The printed list is also available here
The second section covers the tools and demonstrates exactly how to measure and mark a 16 ft ladder for cutting 5 hoist platforms.
The third section covers cutting the ladder and other materials such as braces and bars that mount the hoist motor and pulley.
The forth section concludes the assembly of the platform.
The fifth section shows how to attach everything to the ladder.
A bonus video is included that records the platform assembly from beginning to end in 23 minutes.

Advantages of having the plans:

Availability: With these plans you can use ANY alumininum extension ladder that isavailable to you.

Time: The first hoist I built took several days to design and assemble. There have been several major engineering design improvements since then to make the hoist stronger, lighter and more efficient. The improvements (and 2 years of testing) has developed an excellent, safe and professional product.

Money: For about fifteen hundred dollars LESS than the price of a tranzsporter . you can have a hoist that lifts MORE weight than the commercial brands

Convenience: Shopping for the materials is simple when you have the exact list of parts you need. Without the list you'll probably have to make at least a half dozen trips back to the hardware store.

Valuable tips: I can show you how to save at least $50 on materials - that's worth the price of these plans alone.

Ease: You will get the entire process on video to watch, rewind and re-watch. Everything is explained, step-by-step, and you will SEE how it is done. This is NOT a list on paper with some sketches and comments, there are 5 video sections, about 20 minutes each. This is by far the best way to convey the information.

Confidence: Before you start chopping up a $400 extension ladder you need to know where and how to cut it. A minor mistake in that stage of the preparation would be more expensive than the cost of these plans.

Notes for extending the length.

Every week I get email and phone calls about making the ladder reach higher.

Here are some things to consider:

First, keep in mind that you can only use the BOTTOM section of a ladder because the platform can't transverse to the smaller size of the upper section of an extension ladder. If you want to reach over 20 feet (the maximum length of a section of an extension ladder) you'll need two or more ladders and you'll have to butt the rails like a train track and sandwich them with plates using 8 bolts in each plate. When you splice two ladders they will be weak at the splice and the ladder will want to sway under weight. That will jam the platform - if it sways too much. You can avoid this by keeping the load under 200 lbs. Also, keep the ladder as vertical as possible during use. The more you lean it (with the bottom farther away from the building) the more the weight of the material will be transferred to the splice.

Second, you can gain 3 to 5 extra feet by putting the ladder on the trailer or back of a pickup. That saves a lot of work if the ladder is located near the materials that were brought to the job. This way, the materials can be put directly on the hoist, and raised to the roof, without first unloading to the ground.

Third, the electric motor only has 40 ft of cable. The motor is attached to the bottom of the ladder because the controls are only 6 ft long. That means the cable has to go up to the pulley at the top and back down to the platform. A 20 ft ladder will use almost all the cable that comes on the spool. If you plan to splice 2 ladders you'll have to add 20 more feet of cable. Since half the cable is never wound up on the spool you can use the same electric motor. Some people have suggested attaching the hoist to the top of the ladder but the platform will hit it on the way up and it won't reach the top. Also, it is not safe to operate the motor from the rooftop. You would have to lean over the edge to watch it and to see when it is loaded - which is NOT a good idea.

I recommended that for extra support a wide board (about 4 ft long) should be attach (to the back of the ladder - with the ladders joining in the middle of the board.) Put U bolts around the rungs of the ladder and through the board - to prevent swaying at the joint. (When raising a long ladder - especially with added support, is hard to stand up - unless you use a rope and get on top of the building and pull up one end of the ladder.)

Safety notes:

1. This is NOT A TOY ! Please keep it away from children. It *looks* like something that is fun to play with but the power generated by a 880 lb. hoist motor has the potential to break bones. If someone puts their arm or leg between the rungs of the ladder - while someone else operates the controls - a serious injury is highly probable. Unlike gas motors the electric motor doesn't need cranking - all it needs is the push of a button. The safety of this equipment is YOUR responsibility. I'm only selling a part of the kit, like the hardware store sells the nuts, bolts and ladder.

2. The top of the ladder should always be tied off to a secure point that would prevent it from falling backward or to the side. This is a safety code requirement at most construction sites.

3. The ladder should lean about 15 degrees against a secure surface. If the ladder is too vertical the weight of the material on the platform could cause it to lean back away from the building. If the base of the ladder is too far from the building the material will cause excessive friction against the railing and possibly jam the platform or cause the material to fall off. The platform is built at a 15 degree angle so when it is level with the ground the ladder is in the correct position.

4. The load being lifted needs to be balanced a best you can. An unbalanced load can spill or cause an unsecure ladder to fall.

5. The ladder, platform, hoist and cable should be inspected before and after each use and repaired before use if a problem is found. If you have ever operated a winch or hoist you know that it's important to always keep tension on the cable. Unwinding more than you need and creating a "bird nest" on the motor spool will cause excessive wear to a cable. Remember that rain on an electric motor will cause internal rust and shorten the normal lifespan.

6. Keep in mind that materials, like a roll of felt, will roll off when the platform is raised all the way to the top.

Please be safe and use common sense and good judgement and watch for power lines. Test your setup with a light load before heavy duty operation.
