Hello, dear readers and DIY!
I’m sure many of You have a chance to raise or lower heavy objects in a variety of ways.
For example, you need to dismantle the concrete part of the Foundation, to raise the curb, or pull a piece of concrete from the old fence.
A similar problem occurs in the case that it is necessary to lower heavy objects into the basement, or up in the attic.
In this article, the author of the YouTube channel “Made in Poland” will tell You how he made a special lift in the form of a tripod, which easily solve these problems.
This device is easy to make, but it will take a small amount of welding.
— Manual windlass (tape)
— Manual winch (steel cable)
— Tow strap 3T
— Strip steel, profile pipe, plastic plugs
Bolts M10, lock and extra long nuts, washers, anchor
Chain, bolts with rings, snap hooks
The tools used by the author.
— Magnetic area for welding with adjustable angle
— Welding mask chameleon
— The welding machine
— A ratchet
Drilling machine, step drills
— An angle grinder, cutoff and grinding discs
— Drill, cobalt drill bits for metal
— Belt grinding machine
— Digital caliper, spring clips
— Vise, marker, square, ruler, compass, core, hammer.
The process of making.
The heart of this unit will be here this manual winch with steel cable, rated to 450 kg.
The author decided to slightly modify it, replacing the rope tow tapethat can withstand 3 tons.
First, he removes the rope from the drum.
Then unscrews the lock nut, the axle pulls out and removes the drum.
At some distance from the center in the lateral parts of disc of drilled holes in one of them tapped. So installed the bolt, which will hold the end of the tape.
Windlass going, and the drum is wound the tape.
However, the tape width was less than the distance between the discs almost 13 mm. This disadvantage must be eliminated.
Steel strip thickness 12 mm master cut two rectangular pieces that primatyvajutsja between welding.
The resulting square is marked with a circle equal to the diameter of the discs of the drum.
With the help of drill press and step drill, the author makes a couple of holes for the axis of the drum and bolt.
Mitts worn down, and parts are disconnected. Now excess material can be cut.
Final fitting of the outer edges of the parts is done on the belt grinding machine.
Both Crescent and put in its place, and are welded to the drive drum through the standard holes.
Now the tape is laid straight, without offsets in different directions.
Of course, such a spacer could be made from normal plywood, because a special burden will not be.
By the way, you can buy ready-made belt winch.
Next, you need to make a platform to which is mounted the winch itself, and three legs.
On a rectangular billet is transferred and cernada marks for the holes the mounting bolts.
Drilling the author performs on the machine using the coolant. Then the holes tapped M10.
It is to fix the body of the winch bolts with hex heads.
Steel strips are cut six square details for the eyes. Putting them in a package, the author of catch them together by welding.
In the center of the received packet is drilled through hole with a diameter of 10 mm.
Three blanks for the legs are cut from square profile tube 50X50 mm.
After that, the base is welded on lugs.
Between the eyelets, the author waril three additional ribs. After tacking should finally boil the seams, and carefully to clean them.
In the upper ends of the pipes clogged plastic plugs. Also drilled holes for bolts M12.
Now you can pin the legs in their places by bolts with lock nuts.
Unfolding the tripod on a flat surface, the author notes at the ends of the legs of a line, parallel to the floor.
The pipe ends are cut at an angle to the ground, and welded on a reference platform.
On one of the legs, on the inside, will be assigned to the end of the tape with the hook.
To create the mount, the author cut a couple of rectangular parts, and drilled holes in them for bolts.
The procurement was given a more ergonomic shape. Aligning the plate relative to the legs of the angle bracket, and the fixing spring clip, the author welds them.
The bolt is fixed with a locking nut and it clings to the hook.
In order to make the legs not separated, we have to fix them in the open position.
Stepping back from the top of the legs at 50 cm, they drilled holes and tapped M10.
In the received hole screwed bolts with rings, and additionally fixed by welding.
Between the rings stretched the chain to the desired length, and their ends and cling carbines for the ring.
Also, you should make a chain slightly longer, then it will be possible to adjust the opening width tripod, hooking the snap hooks for the chains.
For halving the effort required for lifting, the author will make an outboard unit.
Rastoci cylindrical sleeve with the two sides, it will press a pair of bearings.
Then made simple the design of the suspension hook.
If you use a winch with a steel cable, it is possible to apply and finish the factory suspension with hook (this model is designed for 2 tons).
So lift ready. To protect the structure from corrosion, it is highly recommended to coat all metal surfaces with primer on metal.
Master need to dismantle the concrete blocks left over from the filler of the Foundation.
In the block, drilled the hole and hammered the anchor.
At the end of the anchor bolt is screwed an elongated nut, and it joins the bolt with the ring.
Now you can hook onto the hook-lift and rotate the handle of the winch.
Even here is a large concrete block was ripped from the ground like a carrot!
Incidentally, to rotate the winch using a wrench.
I thank the author for the interesting lift design-tripod!
All good mood, sound health, and interesting ideas!
