¿Cuál es la diferencia entre un polipasto y un puente grúa?

Jul 22, 2025

When it comes to industrial lifting solutions, two common terms often appear interchangeably: hoist and overhead crane. However, while they are related, these machines serve different functions and cater to varying operational needs. For equipment purchasers and plant managers, understanding this difference is essential for selecting the right machinery for lifting, moving, and positioning heavy loads safely and efficiently.

Every YG Crane product is put through a tough series of examinations and meets global quality requirements. Apart from providing a very good service, the firm is also fast in supplying and has a wide experience in the industrial sector. YG Crane is a solution for companies all over the world to improve their material handling systems.

Understanding the Basics

At its core, a hoist is a lifting device—it raises and lowers loads vertically. A hoist can be manually operated, pneumatically driven, or electrically powered. One of the most popular configurations in modern facilities is the electric wire rope hoist, known for its strength, smooth operation, and ability to handle heavier weights compared to chain hoists.

On the other hand, an puente grúa refers to a system that not only lifts a load but also transports it horizontally across a fixed area. It typically integrates a hoist into a broader crane system, allowing for movement across bridges, runways, or rails.

Main Differences Between a Hoist and an Overhead Crane

While both are used for material handling, their structural differences significantly impact their applications.

Here’s a breakdown of the key distinctions:

  • Funcionalidad:
    • Hoist: Primarily used for vertical lifting
    • Overhead Crane: Offers both lifting and directional movement
  • Componentes:
    • Hoist: Includes motor, wire rope or chain, and hook
    • Overhead Crane: Includes hoist, bridge, end trucks, and controls
  • Movilidad:
    • Hoist: Usually fixed or limited in motion
    • Overhead Crane: Covers a wider working area due to its bridge structure
  • Application Scale:
    • Hoist: Suitable for individual workstations
    • Overhead Crane: Ideal for large-scale, multi-point operations like warehouses or shipyards

When to Choose a Hoist

Muchos fabricantes de polipastos offer a range of hoist types to fit different lifting needs. An electric wire rope hoist, for example, is an excellent solution when:

  • You need to lift heavy equipment straight up and down
  • The application is limited to a single point or a small workspace
  • Smooth and reliable operation with minimal manual effort is required
  • Safety and repeatability are essential in lifting precision parts

In environments where overhead movement isn’t necessary, an electric hoist provides a more compact, cost-effective solution.

When to Choose an Overhead Gantry Crane

An overhead gantry crane, which includes a hoist as part of its system, is ideal when your material handling needs go beyond vertical lifting. It’s the go-to choice when:

  • The load must be moved from one part of the facility to another
  • Workspace layout requires flexible load transportation
  • You are handling multiple lifting points over long spans
  • Heavy lifting must be integrated into manufacturing or assembly lines

An overhead crane improves workflow efficiency and reduces the need for forklifts or manual transport, particularly in heavy industry.
