Blok Tuas

How A Lever Block Works

The basic principle of a lever block is to reduce the force applied to an object through the action of a lever. The operator pulls the handle to drive the internal chain or rope to lift or lower the weight. A lever block usually includes the following main parts:

• Menangani: The part used for manual operation. The user generates lifting force by pulling or pushing the handle.
• Rantai: The chain or rope used to connect the weight and bear the weight.
• Mechanical device: It includes a gear and pulley system to help convert the applied force.
• Kait: It is used to connect the weight to ensure safety and stability.

Application Scope

Due to its portability, economy and efficiency, blok tuas are widely used in many industries:

• Konstruksi: Di lokasi konstruksi, Lever Block is often used for vertical transportation of materials, such as steel bars and formwork, especially when space is limited or electric cranes cannot be used.
• Manufaktur: In factories, Lever Block helps workers transfer heavy parts between production lines or install and repair machines.
• Pergudangan dan logistik: In warehouse management, Lever Block is an ideal choice for moving goods and loading and unloading trucks, especially for small warehouses that do not have complex lifting equipment.
• Ship maintenance: In dock and port maintenance operations, Lever Block is used for lifting and disassembling ship parts and is one of the indispensable tools for offshore operations.

What Is the Difference Between Chain Blocks and Lever Block?

Chain blocks and lever blocks are both types of lifting equipment, but they differ mainly in their mechanism and operation. Here’s a breakdown:

Blok rantai:

• Mechanism: Uses a chain and a series of gears and sprockets to lift heavy loads.
• Operation: The chain is wrapped around a drum, and pulling on the chain raises the load. A pawl and ratchet mechanism prevents the load from lowering unexpectedly.
• Keuntungan: Relatively simple, affordable, dan serbaguna, can handle heavy loads.
• Disadvantages: Can be slow to operate, especially for heavy loads, and may require more effort to lift.

Blok Tuas:

• Mechanism: Uses a lever arm to multiply the force applied to lift a load.
  Operation: A lever arm is pulled to lift the load. The lever arm is connected to a system of gears and sprockets that multiplies the force.
• Keuntungan: Fast and efficient for lifting moderate loads, requires less effort than chain blocks.
• Disadvantages: Limited lifting capacity compared to chain blocks, not as versatile for different lifting applications

In a nutshell:

• Blok rantai: Higher lifting capacity, slower, more effort required.
• Lever blocks: Smaller lifting capacity, lebih cepat, less effort required.

The choice between a chain block and a lever block depends on the specific lifting task, including the weight of the object, the height it needs to be lifted, and the available lifting space.

Precautions for Use

As a professional produsen kerekan, we tell you some precautions for using the lever block. Although the lever block is easy to operate, you still need to pay attention to the following matters when using it:

1. Make sure the load-bearing capacity of the equipment matches the actual weight to avoid overloading.
2. Inspect and maintain the lever block regularly to ensure that it is in good working condition.
3. Keep it stable during operation to ensure that the heavy objects are safe and not easy to tip over.
