Home » Lever Block vs. Come Along: Which Wins?
A lever block and a come along are both essential pieces of rigging equipment used for lifting or pulling heavy loads, but they operate on different mechanisms and are suited for different applications. Choosing the right tool for the job is crucial for safety and efficiency. At Safe and Secure Trading Company (SSTC), we often encounter customers unsure of which tool best fits their needs. This article will provide a detailed comparison to help you make an informed decision.
A lever block is a manual lifting device that uses a lever and gears to provide mechanical advantage for lifting heavy objects vertically. It is commonly used in workshops, construction sites, and industrial settings. A come along, also known as a chain hoist or come along winch, is a manual pulling device that uses a ratchet mechanism to provide pulling force, typically in a horizontal direction. It’s frequently used for vehicle recovery, fence stretching, and moving heavy objects over short distances. The goal of this article is to clearly outline the differences between a lever block and a come along, explain their ideal applications, and provide guidance on selecting the right tool for your specific needs.

A lever block is a manually operated lifting device designed to provide significant mechanical advantage, making it easier to lift heavy loads. The construction and operation of a lever block are relatively straightforward, but understanding its key components and how they work together is essential for safe and effective use. We’ve observed that many of our clients initially underestimate the power and precision a lever block can offer.
The key components of a lever block include a lever, a load chain, top and bottom hooks, and an internal gear system. The lever is the handle that the operator uses to apply force. The load chain is a high-strength chain that supports the weight being lifted. The hooks are used to attach the lever block to the load and the anchor point. The internal gear system multiplies the force applied to the lever, providing the mechanical advantage needed to lift heavy objects.
The lever mechanism in a lever block works by using a series of gears to reduce the amount of force required to lift a heavy load. The operator pulls on the lever, which turns a series of gears, ultimately pulling the load chain and lifting the object. The gear ratio determines the mechanical advantage; a higher gear ratio means less force is needed to lift the load, but the lifting speed is slower. For many of our clients here in Dammam, we’ve seen that understanding this mechanical advantage is crucial for selecting the right lever block for their specific lifting requirements.
Lever blocks are ideally suited for vertical lifting applications where precise control and high lifting capacity are required. These tools excel in situations where maneuverability in confined spaces is key, and where the user requires fine adjustments to the load’s position.
Lever blocks are commonly used for lifting heavy engines in automotive repair shops, hoisting pipes in construction sites, and moving equipment in industrial settings. Their vertical lifting capability makes them indispensable in situations where overhead cranes or forklifts are not practical or available. For example, we once worked with a client who needed to lift heavy pipes in a narrow trench; they found a lever block was the only practical solution.
One of the key advantages of a lever block is the precise control it offers. The operator can make small, incremental adjustments to the load’s position, which is essential when aligning machinery or installing equipment. This precision minimizes the risk of damage and ensures accurate placement.
Lever blocks are compact and lightweight, making them ideal for use in confined spaces. They can be easily positioned and operated in areas where larger lifting devices would be impractical. This maneuverability is particularly useful in maintenance and repair work, where access may be limited.
A come along is a manual pulling device designed to provide significant pulling force, primarily in horizontal applications. Understanding its construction, operation, and ideal applications is essential for using it safely and effectively. We often advise our customers on selecting the right come along based on their specific pulling needs.
A come along is a mechanical device used to pull objects together or to move heavy loads horizontally. It consists of a cable or chain, a ratchet mechanism, and hooks or clamps for attaching to the load and the anchor point. The ratchet mechanism allows the operator to apply force incrementally, pulling the load a short distance with each stroke.
The key components of a come along include a cable or chain (depending on the model and load capacity), a ratchet mechanism, and hooks or clamps. The cable or chain provides the pulling force. The ratchet mechanism allows the operator to apply force in small increments, and the hooks or clamps are used to secure the come along to the load and the anchor point.
The ratchet mechanism in a come along works by using a pawl that engages with a toothed wheel. With each stroke of the handle, the pawl moves the wheel forward, pulling the cable or chain a short distance. The ratchet prevents the wheel from turning backward, maintaining the pulling force.
Come alongs are ideally suited for horizontal pulling applications where a longer pulling distance is needed and where portability is crucial. These tools are commonly used for vehicle recovery, fence stretching, and moving heavy objects over short distances.
Come alongs are frequently used for pulling stuck vehicles out of mud, stretching fences, and aligning objects during construction or repair work. Their horizontal pulling capability makes them indispensable in situations where a direct pulling force is required. For example, we once worked with a client who needed to stretch a long fence; they found a come along was the most efficient tool for the job.
One of the key advantages of a come along is its ability to provide a longer pulling distance compared to a lever block. This is particularly useful when moving objects over uneven terrain or when a direct line of pull is not possible. The extended reach allows the operator to work from a safe distance.
Come alongs are generally lightweight and portable, making them easy to transport and use in various locations. This portability is particularly useful for contractors and maintenance crews who need to move heavy objects on different job sites.
While both lever blocks and come alongs are valuable pulling tools for material handling, significant differences exist in their mechanism, ideal applications, load capacity, and safety considerations. These differences dictate which tool is best suited for a given task. Understanding these distinctions is crucial for safe and effective use.
The fundamental difference between a lever block and a come along lies in their mechanism and operation. A lever block uses a gear-driven system to provide mechanical advantage for vertical lifting, while a come along employs a ratchet-based system for horizontal pulling.
A lever block operates by using a lever to turn a series of gears, which then pull on a chain to lift the load. The gear ratio determines the mechanical advantage, allowing the operator to lift heavy objects with relatively little effort. The gear-driven system provides precise control and smooth operation.
A come along operates by using a ratchet mechanism to pull a cable or chain. With each stroke of the handle, the ratchet advances the cable or chain, pulling the load a short distance. The ratchet mechanism allows for incremental adjustments and maintains the pulling force.
Lever blocks and come alongs are designed for different types of applications. Lever blocks are superior for vertical lifting, while come alongs are superior for horizontal pulling.
The gear-driven mechanism of a lever block provides the precise control and high lifting capacity required for vertical lifting applications. Lever blocks are ideal for lifting engines, pipes, and other heavy objects vertically.
The ratchet-based mechanism of a come along provides the pulling force and extended reach required for horizontal pulling applications. Come alongs are ideal for vehicle recovery, fence stretching, and moving heavy objects horizontally over short distances.
Both lever blocks and come alongs have specific load capacities and safety considerations that must be taken into account. Exceeding the working load limit (WLL) can result in equipment failure and serious injury.
Lever blocks typically have load capacities ranging from 0.75 tons to 9 tons or more, depending on the model and manufacturer. For example, a typical lever block might have a WLL of 3 tons. Come alongs typically have load capacities ranging from 1 ton to 4 tons or more, depending on the model and manufacturer. For instance, a come along winch might have a WLL of 2 tons.
It is crucial to never exceed the working load limit (WLL) of a lever block or come along. Overloading these tools can cause them to fail, resulting in dropped loads and serious injuries. Always choose a tool with a WLL that is greater than the weight of the load being lifted or pulled.
Both lever blocks and come alongs are often equipped with safety features such as overload protection and safety latches. Overload protection mechanisms prevent the tool from being overloaded, while safety latches on the hooks prevent the load from slipping off. These safety features are essential for preventing accidents and ensuring safe operation.
To further illustrate the differences and ideal uses of lever blocks and come alongs, let’s consider a few real-world scenarios. These examples will highlight why one tool is better suited than the other for each situation.
