Hand Winches Endure As Reliable Tools for a Century

What kind of tool can move heavy objects without electricity, relying solely on human power, and even gently straighten trees? The answer is the come-along, a seemingly unremarkable mechanical device that plays a vital role in industries such as agriculture and construction.

A come-along, also known as a power puller, is a manually operated winch. Its core component is a drum with a ratchet mechanism, which winds a steel cable or nylon strap to pull objects. Unlike electric winches, come-alongs require no power source, making them uniquely advantageous in remote locations or situations requiring precise control.

The history of come-alongs dates back to the early 20th century. Records indicate that Abraham Maasdam of Deep Creek, Colorado, invented the first come-along around 1919. His son, Felber Maasdam, commercialized the tool around 1946. Its simplicity and practicality led to rapid adoption, with many manufacturers producing similar models.

Early come-alongs primarily used steel cables, suitable for hauling heavy loads. However, as applications expanded, users discovered limitations when working with trees. Steel cables could damage bark during slow, sustained pulls required for tree straightening. This led to the development of nylon-strap come-alongs, which offered greater flexibility and cushioning, preventing excessive pressure and trunk splitting.

In 1935, a heavy-duty hybrid come-along combining chains and steel cables was tested by railroads. However, its complex design and operational challenges prevented widespread adoption compared to standard cable models.

Though visually similar to ratchet lever hoists, come-alongs serve distinct functions. Come-alongs are designed for horizontal pulling, while ratchet lever hoists specialize in vertical lifting. For safety reasons, come-alongs should never be used for overhead lifting operations.

Another tool for moving heavy objects is the cable puller. Unlike come-alongs, cable pullers lack drums and ratchets. Instead, they grip cables directly, enabling use with unlimited cable lengths. This design makes cable pullers preferable for long-distance pulling applications.

While come-alongs are simple to operate, improper use can cause accidents. Follow these precautions:

1. Select the appropriate model: Choose a come-along with sufficient capacity for the object's weight and size.

2. Inspect equipment: Check cables or straps for wear or damage, and ensure the ratchet mechanism functions properly.

3. Secure connections: Fasten the come-along firmly to the object to prevent slippage.

4. Pull gradually: Apply force slowly and evenly, avoiding sudden movements.

5. Avoid overloading: Never exceed the come-along's rated capacity.

6. Wear protective gear: Use gloves, helmets, and other safety equipment to prevent injuries.

Technological advancements are driving innovation in come-along design. Future models will likely feature enhanced intelligence and reduced weight for easier, safer operation. Some newer come-alongs already incorporate digital displays showing real-time tension to prevent overloading. High-strength lightweight materials will further minimize operator strain.

As a simple yet indispensable manual tool, the come-along continues serving diverse applications. Understanding its history, mechanics, uses, and safety measures enables more effective and secure utilization across various tasks.
