Electric Hoist VS EOT Crane

What Are They? The Core Distinction

Polipasto eléctrico

• What it is: Essentially a motorized lifting unit. It’s a self-contained device focused solely on hoisting and lowering a load using a chain or wire rope.

• Function: Primarily vertical movement. It can be moved horizontally, but only if mounted onto a separate supporting structure.

• Mobility: It is not inherently mobile horizontally on its own. You need to mount it onto something like a:

  • Jib Crane (Wall-Mounted or Freestanding): Provides limited horizontal reach in an arc.

  • Gantry Crane (Portable or Fixed): Provides travel along a defined path.

  • Monorail System: Travels along a fixed I-beam track.

  • Manual Trolley: Requires an operator to push/pull it along a beam.

  • Motorized Trolley: Provides powered travel along a single beam.

EOT (Electric Overhead Travel) Crane

• What it is: A complete overhead material handling system. It integrates multiple components:

  • Bridge: The main horizontal beam(s) that spans the bay width.

  • End Trucks: Units at each end of the bridge that house the wheels for travel along the runway beams.

  • Runway Beams: Heavy beams (usually mounted on building columns or a dedicated support structure) that the crane travels along the length of the bay.

  • Hoist: The actual lifting unit (which is often an Electric Hoist!) mounted on a trolley.

  • Trolley: The unit that carries the hoist and moves it across the bridge (bay width).

  • Crane Controls: For operating bridge travel, trolley travel, and hoisting.

• Function: Provides full three-dimensional movement within a defined rectangular area (the bay): Up/Down (Hoist), Left/Right across the bay (Trolley Travel), Forward/Back along the bay (Bridge Travel).

• Mobility: Has built-in powered horizontal mobility in two perpendicular directions (along the runway and across the bridge).

Key Comparison Factors

Feature	Polipasto eléctrico	EOT Crane
Movement	Primarily Vertical Lifting/Lowering	Full 3D Movement (Up/Down, Across, Along)
Complexity	Simpler, Single Unit	Complex System (Bridge, Trolley, Hoist, Runway)
Instalación	Simpler, Mounts to existing beam/structure	Complex, Requires robust runway support structure
Coverage Area	Limited to reach of supporting structure	Covers entire rectangular bay area
Capacity	Wide Range (e.g., 0.25 tonelada de 50+ montones)	Wide Range (e.g., 1 tonelada de 500+ montones) – Typically higher max capacities common
Cost	Lower (Unit cost + Simpler Mounting)	Higher (System cost + Structural work)
Footprint	Minimal floor space used	Requires clear overhead space; runway beams need support
Flexibility	Highly flexible; easily relocated/moved to new mounts	Fixed location; difficult/expensive to move
Best Suited For	Localized lifting points, workstations, under jibs/gantries, lower budgets, simpler needs	Bay-wide coverage, high throughput, moving loads significant distances, heavy/awkward loads requiring precise placement

When to Choose an Electric Hoist

• 1. You need lifting at specific, fixed points (e.g., loading docks, workstations, assembly points).
• 2. Your lifting needs are localized and don’t require moving loads across a large area.
• 3. Budget is a primary constraint (lower initial equipment and installation cost).
• 4. You have existing suitable support structures (like strong beams for a jib crane) or can use a portable gantry.
• 5. Floor space is limited, and you need minimal overhead structure.
• 6. You need mobility and flexibility (e.g., using a portable gantry crane with a mounted electric hoist).

When to Choose an EOT Crane

• 1. You need to cover a large rectangular area (e.g., entire workshop bay, warehouse aisle).
• 2. You require efficient horizontal transport of loads across significant distances within that bay.
• 3. Throughput is high, and precise load placement over a wide area is critical.
• 4. You handle very heavy, bulky, or awkward loads that need full overhead maneuverability.
• 5. Your building structure can support the runway beams and crane loads (or you can build dedicated support).
• 6. Long-term efficiency gains justify the higher initial investment.

Remember this key point: The hoist unit on an EOT crane is almost always an Polipasto eléctrico! The EOT crane provides the comprehensive travel system, while the hoist itself handles the core lifting function. So, it’s not truly “hoist vs crane,” but rather “standalone hoist on a simple support vs. hoist integrated into a complex overhead travel system.”

Don’t get caught in the trap of thinking one is universally superior. The best choice depends entirely on your operational requirements:

• Need versatile lifting at a point? An Electric Hoist on a jib, gantry, or monorail is likely your efficient and cost-effective solution.
• Need to dominate a large bay with full 3D movement? An EOT Crane system, powered by its integral electric hoist, is the powerhouse you need.

Carefully analyze your lifting tasks, coverage area, budget, building structure, and workflow. Understanding the fundamental difference between the standalone lifting unit (Polipasto eléctrico) and the complete overhead handling system (EOT Crane) is the first step to making the optimal investment for your productivity and safety.
