Electric Hoist Gantry Crane: A Complete Sizing & Selection Guide
Choosing the right electric hoist gantry crane comes down to matching load geometry, duty class, span, hook lift, and power supply to your yard or shop workflow. This guide explains when to choose gantry + electric hoist, how to configure speeds and controls, what safety packs to specify, and the information engineers need to quote accurately.

10.FAQs
1) What Is an Electric Hoist Gantry Crane
The gantry crane is equipped with an electric hoist and runs laterally along one or two main beams, and travels longitudinally on ground tracks or without tracks. Compared with bridge cranes, gantries avoid runway steelwork in buildings and excel outdoors or in mixed indoor/outdoor flows. Electric hoists (wire rope or chain) provide precise, low-noise lifting with VFD control and wide accessory support.
2) When to Choose Gantry + Electric Hoist
1. Operating conditions: Such as open-air warehouses, freight yards, loading and unloading sites inside and outside workshops, etc.
2. When the lifting capacity is medium (typically 1-32 tons) : It is more economical compared to heavy-duty gantry cranes and can meet the lifting requirements of medium and small-sized goods (such as steel and equipment).
3. When the lifting height/span is flexibly adapted: The span (such as 5-30 meters) and lifting height (5-15 meters) can be customized as needed to adapt to different site sizes.
4. When pursuing cost performance and convenience: The structure is simpler than that of bridge cranes, with lower installation and maintenance costs. Moreover, the electric hoist is easy to operate and suitable for daily production use.
3) Hoist Type × Gantry Type Matrix
| Use Case | Hoist Type | Gantry Type | Why |
|---|---|---|---|
| 0.5–5 t workshop moves, low headroom, frequent repositioning | Chain hoist | Portable / light single-girder | Compact, economical, easy to relocate |
| 5–32 t indoor/outdoor cells, precision set-down | Wire rope hoist (compact) | Single-girder | Smoother lifting, better duty capability |
| 5-50t indoor and outdoor storage yards, heavy load/long items | Wire rope hoist (open winch) | Double-girder | Higher stiffness, span, hook approach |
| Corrosive/coastal/low-temp environments | Wire rope or chain (with protection) | Single or double girder | IP/anti-corrosion/low-temp packages |
| Long parts (girders/coils/slabs) needing custom below-hook | Wire rope hoist | Double-girder | Pairs well with spreaders, C-hooks |
(You can mix hoist & gantry styles; engineering fit is case-by-case.)
4) Core Parameters to Define
A. Load
Maximum load (t
B. Span
The horizontal distance between the centerlines of two parallel support tracks;
C. Lifting height
The vertical distance of the hook (or lifting device) from the lowest working position to the highest working position.
D. Work Level (ISO/FEM)
According to the hourly cycle, daily working hours and load spectrum matching, generally A1 – A8.
E. Speed
Hoist: fine positioning + productivity (e.g., 0.5–8 m/min range-based)
Trolley: smooth approach across span (e.g., 2–20 m/min)
Gantry travel: throughput & yard layout (e.g., 3–30 m/min)
5) Power Supply & Outdoor Packages
Power options
Cable reel (long runs, simple maintenance)
Seamless or single stage sliding contact lines (continuous feeds, reduced drag)
Voltage/frequency to match site (e.g., 220-660 V, 50/60 Hz)
Outdoor kits
Wind area check, rail clamps / storm locks (for rail gantries)
IP-rated enclosures, heater/anti-condensation for cabinets
Corrosion protection (paint system, stainless fixings)
Low-temperature packages for sub-zero sites
6) Safety, Controls & Productivity
Overload limiter, upper/lower limiters, travel limit switches
Anti-sway control + inching mode for precision set-down
VFD on all axes for gentle acceleration and reduced wheel/rail wear
Remote control, cab control, or both; optional cameras/lighting
Data & diagnostics: fault logs, run-time counters, maintenance prompts
Emergency stops, phase loss/reversal, surge protection
7) Applications & Typical Attachments
Precast & Construction: molds, girders, box segments → spreader beams, mold frames
Steel & Metals: coils, slabs, plates → C-hooks, magnets, plate clamps
General Fabrication: jigs, fixtures, machine tools → rotating hooks, adjustable spreaders
Marine & Energy: blocks, nacelles, transformers → custom frames, tandem lifts
