ก 12 ton overhead crane with electric hoist (also called a 12t EOT crane or 12t bridge crane) is a reliable material handling solution for workshops, คลังสินค้า, production lines and maintenance facilities that need to lift, move and position loads up to 12,000 กก. It combines an overhead traveling bridge with an electric wire rope hoist, giving you full three-dimensional coverage of your work bay with precise, repeatable lifting.

By structure, the 12 ton overhead crane with electric hoist is available in two main designs:

12 ton single girder overhead crane with electric hoist

Double girder overhead crane with electric hoist

• ◆ Single girder overhead crane with electric hoist – one main girder, economical and space-saving
• ◆ Double girder overhead crane with electric hoist – two main girders, built for heavier duty and longer service

This guide explains how each type works, compares their specifications and costs, and helps you choose the right 12t crane for your application.

What Is a 12 Ton Overhead Crane with Electric Hoist?

The 12 ton overhead crane with electric hoist consists of four core systems:

• 1. Bridge structure – one or two main girders supported by end carriages, traveling along runway rails fixed to the workshop columns
• 2. Electric hoist – a wire rope electric hoist (CD/MD type or European-style low headroom hoist) that lifts and lowers the load
• 3. Travel mechanisms – hoist travel (across the span) and crane travel (ตามแนวรันเวย์), driven by geared motors with brakes
• 4. Control system – pendant pushbutton, wireless remote control or cabin operation, with optional variable frequency drive (VFD) for smooth speed control

Because the crane runs overhead, it keeps the factory floor clear for people, forklifts and production equipment – making it one of the most space-efficient ways to handle 12-ton loads.

Two Structural Types of 12T Overhead Crane with Electric Hoist

1. Single Girder Overhead Crane with Electric Hoist

The single girder overhead crane with electric hoist uses one main girder (welded box girder or H-beam). The electric hoist runs along the bottom flange of the girder, and the girder itself is supported by two end carriages that travel along the runway.

Single Girder Overhead Crane with Electric Hoist

Key features:

• ◆ Compact and lightweight – lower dead weight means lighter runway and building loads
• ◆ Low headroom – the hoist sits close under the girder, maximizing usable lifting height in low buildings; European-style low headroom hoists cut required headroom by roughly 15–30% compared with conventional designs
• ◆ Fast, simple installation – can often be installed in a single working day with basic tooling
• ◆ Low maintenance and low cost – fewer moving parts and a simpler structure keep both capex and upkeep down
• ◆ Wide capacity range – single girder cranes are typically built from 1 t up to 20–32 t depending on the manufacturer, so a 12 t rating is fully supported

Typical parameters (single girder): span 7.5–31.5 m (7.5–22.5 m for European top-running designs), lifting height 6–30 m, working class A3–A5, hoist speed 0.8–8 m/min with dual-speed option (e.g. 8/0.8 เมตร/นาที).

Best suited for: light to medium duty, intermittent lifting, คลังสินค้า, assembly lines, machine shops and general fabrication – where budget and headroom matter more than continuous heavy operation.

2. Double Girder Overhead Crane with Electric Hoist

The double girder overhead crane with electric hoist uses two main girders, with a trolley-mounted electric hoist running on rails on top of the girders. The hoist trolley is separate from the girders, which is why this design can lift heavier loads and achieve greater heights.

Double Girder Overhead Crane with Electric Hoist

Key features:

• ◆ Higher lifting capacity and height – the trolley-on-top layout allows lifting heights beyond 18–30 m and spans up to 31.5 m or more
• ◆ Higher duty class – designed for A5–A7 working duty, supporting continuous, high-frequency operation
• ◆ Better load stability and positioning accuracy – four wheels and a rigid frame give smoother, more precise movement, important for mold, die and precision component handling
• ◆ Easier maintenance – a maintenance platform along the girder gives safe access to the hoist, trolley and electrics
• ◆ Room for a cabin or additional equipment – a crane cabin, magnet or grab can be integrated when needed

Typical parameters (double girder): span 10.5–31.5 m, lifting height 12–30 m, working class A5–A7, lifting speed 0.8–8 m/min (dual-speed 8/0.8 or 7/0.7 เมตร/นาที), crane travel 20–30 m/min.

Best suited for: medium to heavy duty, continuous production, steel fabrication, foundries, precast concrete plants and any facility needing high lifting height or intensive work cycles.

• ◆ Electric wire rope hoist – available as a CD/MD dual-speed hoist or a European-style low headroom hoist; both deliver smooth lifting with mechanical and electrical braking. For a 12 t crane, twin-speed control (e.g. 5/0.8 or 8/0.8 เมตร/นาที) is standard practice for safe load placement
• ◆ Main girder(ส) – optimized box girder design analyzed with finite element analysis (FEA) to reduce weight while maintaining strength and deflection limits
• ◆ End carriages – house the travel wheels and geared motors; equipped with buffers and rail sweeps
• ◆ Power supply – safety conductor rail or festoon cable system
• ◆ Control system – pendant pushbutton, wireless remote, or cabin control; VFD (variable frequency drive) optional for smooth acceleration and precise positioning
• ◆ Safety devices – upper/lower limit switches, overload limiter, travel limit switches, emergency stop, warning horn, anti-collision protection and lightning protection (outdoor installations)

How to Choose: Single Girder or Double Girder 12T Crane?

Answer these questions before you buy a 12 ton overhead crane with electric hoist:

Weihua Factory

• 1. How often will it work? Occasional lifting → single girder. Continuous, multi-shift operation → double girder.
• 2. What is your building height? Low headroom → single girder with a low headroom hoist. High building → double girder wins on lifting height.
• 3. What span and lifting height do you need? If you need spans above ~25 m or lifting above ~18 m, double girder is usually the right choice.
• 4. What is your budget? Single girder is the most economical option; double girder costs more but pays back in duty and service life.
• 5. Do you need precision or a cabin? Double girder gives smoother positioning and supports cabin operation, magnets and grabs.

Rule of thumb: for light-medium duty, budget-conscious projects and low workshops, choose the single girder overhead crane with electric hoist. For heavy, continuous duty, high lifting height or precision handling, choose the double girder overhead crane with electric hoist.

Applications of a 12 Ton Overhead Crane with Electric Hoist
