رافعة جسرية كهربائية متحركة (EOT) ذات عارضة واحدة

Engineered for high-efficiency indoor and outdoor material handling, the VOITTO Single Girder EOT Crane (Electric Overhead Travelling Crane) delivers maximum hook coverage, reduced runway wheel loads, and low-headroom building clearance for capacities from 1 Ton to 32 Ton. This product features a welded box-section main girder structure, is equipped with a two-speed or variable-frequency drive (VFD) system (for overhead and trolley travel), and incorporates an IP55-rated electrical system designed to withstand humid and tropical climates. This series of cranes is particularly well-suited for use in steel fabrication shops, automotive manufacturing plants, power plants, and hazardous chemical handling areas.

مقدمة المنتج

A Single Girder EOT Crane consists of a single heavy-duty bridge girder supported on two end carriages, an electric wire rope hoist or low-headroom European hoist that travels across the bottom flange of the main girder, and a synchronized dual-motor drive mechanism that moves the entire bridge along elevated runway rails. Compared to double girder systems, a single girder EOT crane reduces overall crane deadweight by 25% to 40%, significantly lowering the static and dynamic wheel loads transmitted to your factory columns and runway corbels.

To match diverse industrial building layouts, duty cycles, and project budgets, VOITTO Crane manufactures four specialized configurations of single girder EOT cranes: the LD General-Purpose Type, the HD European Low-Headroom Type, the LX Underslung Suspension Type, and the LB Explosion-Proof Type. Whether you are retrofitting an existing low-clearance warehouse or preparing an international engineering tender for a new greenfield plant, our engineering team delivers customized bridge cambering, exact wheel load charts, and General Arrangement Drawings (GAD) within 24 hours.

Single Girder EOT Crane Price

The price of a single girder EOT crane varies depending on its configuration, span, lifting height, control method, and local installation requirements. The table below lists the reference price ranges for common configurations. All quotes are in U.S. dollars (USD) on FOB shipping. ملاحظة: The actual price will depend on the specific specifications.

أجزاء رافعة EOT ذات عارضة واحدة

The single-beam EOT crane is composed of multiple parts, such as a main beam, two end beams, a travel mechanism, a lifting mechanism, an electrical system, and safety devices. These components work together to complete the lifting and handling of materials. The functions of each component are as follows:

• الشعاع الرئيسي: Bracket for horizontal installation of the lifting mechanism and determination of the lifting span.
• العارضة النهائية: Mounting overhead travel mechanism, Longitudinal movement of the crane.
• آلية الرفع: A Device to move the hook up and down. It consists of a motor, gearbox, brake, drum, wire rope, hook, and block.
• Remote Controls: Device for controlling the operation of cranes
• Electrical Systems: Powering the crane to run.
• جهاز الأمان: A protective device against crane lifting overloaded weights.

الأسئلة الشائعة

How much does a 5 ton or 10 ton single girder EOT crane cost?

A standard 5 ton LD Single Girder EOT Crane (span 10.5m–16.5m, lifting height 6m–9m) typically costs between $4,200 and $7,800 FOB, while an upgraded 5 ton HD European Single Girder EOT Crane ranges from $8,500 to $13,500. For a 10 ton Single Girder EOT Crane, prices range from $6,800 to $12,500 for the LD model and $11,500 to $18,800 for the HD European model. Final pricing depends on exact span length, lifting height, VFD control options, and whether runway rails and busbar systems are included.

What is the difference between an LD type and an HD European single girder EOT crane?

The LD model is a standard-duty (ISO M3–M4 / A3–A4) crane paired with a CD1 or MD1 hoist, designed for economical general workshop lifting. The HD model is a European crane (ISO M5 / FEM 2m / A5) equipped with a compact low-headroom hoist, VFD stepless speed control on both Long Travel (LT) and Cross Travel (CT) drives, and a welded box girder. The HD crane saves 300–600 mm of building headroom, reduces runway wheel loads by 15%–25%, and delivers smoother, anti-sway load positioning.

When should I choose a single girder EOT crane vs. a double girder EOT crane?

A single girder EOT crane is the most cost-effective choice when your rated lifting capacity is 20 tons or less (up to 32 tons for light-duty bays), your span is under 28.5 meters, and your working duty is ISO M3 to M5. If your capacity exceeds 20–32 tons, your span exceeds 30 meters, or your facility requires continuous heavy duty (ISO M6–M8), full-length maintenance walkways, or dual main/auxiliary hooks, we recommend upgrading to a double girder EOT crane.

Can VOITTO design single girder EOT cranes compliant with IS 3177 / IS 807 or FEM standards?

Yes. VOITTO Crane engineers single girder EOT cranes in full compliance with international standards, including FEM 1.001, ISO 4301, DIN 15018, CMAA 70, GB/T 3811, and Indian Standards IS 3177 / IS 807 (Class II and Class III medium-to-heavy duty). We also customize electrical panels for 380V/400V/415V/440V (50Hz/60Hz).

What is the production lead time, shipping method, and installation support?

Standard LD, HD, and LX single girder EOT cranes require 20 to 35 working days for manufacturing and factory load testing; LB explosion-proof models require 25 to 35 working days. Main girders are engineered with high-strength bolted splice joints or telescopic designs to fit inside standard 40ft High Cube (40HQ) or Open Top (40OT) containers. We provide 3D installation videos, wired-and-tested plug-and-play electrical harnesses, complete English manuals, and optional on-site engineer commissioning worldwide.
