A come along is a versatile, compact tool that allows you to multiply your pulling power for a variety of tasks. From heavy lifting and pulling to winching and tensioning, a come along can save you time and effort. But before you can put this powerful tool to work, it’s important to understand how to use a come along safely and effectively. Here’s a step-by-step guide to help you get started.
First, assess the load you need to move. Come alongs have a maximum capacity, so it’s important to make sure the tool you choose is up to the task. Next, choose a suitable anchor point. The anchor point should be secure and strong enough to withstand the pulling force of the come along. Once you have selected your anchor point, attach the come along to the load using a sling or chain. Finally, secure the other end of the come along to the anchor point. Now you’re ready to start pulling.
To pull the load, simply crank the handle of the come along. As you crank, the come along will engage its gears, multiplying your pulling power. Continue cranking until the load has been moved to the desired location. When you’re finished, release the tension on the come along by turning the handle in the opposite direction. Finally, detach the come along from the load and the anchor point. By following these steps, you can safely and effectively use a come along to tackle a variety of tasks.
Understanding the Mechanics of a Come Along
A come along, also known as a lever hoist or chain block, is a mechanical device used to exert a large force over a short distance. It is commonly used for lifting, pulling, and tensioning applications in various industries, including construction, automotive, and manufacturing.
The basic principle behind a come along is the use of a lever and a chain. The lever, which has a handle or a ratchet mechanism, is used to apply force to the chain. The chain, which is secured to the load being lifted or pulled, is then drawn through the lever, creating a mechanical advantage that amplifies the force applied.
The mechanical advantage of a come along is determined by the length of the lever and the number of chain wraps around the lever. The longer the lever and the more chain wraps, the greater the mechanical advantage and the heavier the load that can be lifted or pulled.
Come alongs are available in a variety of sizes and capacities, ranging from small handheld models to large industrial-grade units. They are typically rated for a maximum load capacity and a maximum lifting height. It is important to select a come along that is appropriate for the specific application and load requirements.
Parts of a Come Along
The key components of a come along include:
- Lever: The handle or ratchet mechanism used to apply force.
- Chain: The flexible steel chain that is attached to the load and drawn through the lever.
- Load hook: The hook or attachment point where the load is secured.
- Binder: A locking device that secures the lever in position.
- Pawl: A spring-loaded latch that engages the ratchet mechanism, preventing the lever from slipping.
Essential Accessories for Effective Use
To make the most of your come along, it is important to have the right accessories. These items will help you to use the come along safely and efficiently.
1. Winch Strap
A winch strap is a heavy-duty strap that is used to connect the come along to the object you are pulling. The strap should be long enough to reach from the come along to the object, and it should be strong enough to handle the weight of the object.
2. Anchor Point
An anchor point is a secure object that the come along can be attached to. The anchor point should be strong enough to hold the weight of the object you are pulling, and it should be located in a position that allows the come along to pull the object in the desired direction.
3. Snatch Block
A snatch block is a pulley that is used to change the direction of the pull. This can be useful when you need to pull the object in a different direction than the come along is attached to.
4. Tree Protector
A tree protector is a device that is used to protect the bark of a tree when using the come along. This is important to prevent damage to the tree, and it can also help to prevent the come along from slipping.
Tree protectors come in a variety of materials, including rubber, nylon, and leather. The material you choose will depend on the size of the tree and the amount of force you will be applying. For smaller trees, a light-duty tree protector may be sufficient. For larger trees or heavy-duty use, a more durable tree protector will be needed.
To use a tree protector, simply wrap it around the tree trunk and secure it with the provided straps or buckles. The tree protector should be positioned so that it will be between the cable and the bark of the tree. Once the tree protector is in place, you can begin using the come along.
