Double Girder Trolley Type Electric Wire Rope Hoist
A double girder trolley type electric wire rope hoist is used on double girder cranes when the lifting unit needs stable trolley travel, better hook height and a stronger structural layout than a standard underslung hoist.
- Top-running trolley layout for double girder cranes
- Better hook approach and lifting height in many workshops
- Designed for heavier and more frequent lifting tasks
- Custom capacity, speed, control and maintenance access
Typical use: heavy workshops, machinery assembly, mold handling, steel fabrication and production bays with double girder bridge cranes.
Double Girder Fit
Built for trolley travel on bridge girders.
Better Hook Height
Useful where vertical space matters.
Heavy Duty
Suited to demanding production cycles.
Custom Controls
VFD, remote, cabin and PLC options.
A Trolley Hoist for Stronger Crane Layouts
When the crane structure is double girder, a trolley type hoist can make better use of the bridge frame. It supports smoother load travel and can improve usable hook height compared with many underslung arrangements.
The trolley gauge, wheel load, lifting height, control system and service platform should be reviewed together before final design.
- Good fit for double girder overhead cranes
- Improves hook approach in many heavy workshops
- Supports higher duty and heavier handling routes
- Can include maintenance platform and service access
- Works with radio, cabin, pendant or automated controls
Application Scenes
Trolley type hoists are selected where crane capacity, duty, hook height and trolley stability matter.
Heavy Assembly
Lift large machinery bases, frames and equipment parts.
Mold Handling
Move molds and tooling with controlled travel.
Steel Processing
Handle plate, beams and fabricated structures.
Maintenance Plants
Support equipment overhaul and component replacement.
Production Bays
Provide regular lifting over fixed work cells.
Crane Modernization
Upgrade existing double girder cranes with new lifting units.
Configuration Options
Final configuration depends on load shape, span, lifting height, working frequency and the space available for installation and maintenance.
Custom Trolley Gauge
Matched to the bridge girder spacing.
Dual Brake Package
Used when process risk requires additional protection.
Cabin or Remote Control
Selected around visibility, route length and safety rules.
Technical Planning Points
- Bridge girder spacing and trolley gauge must match.
- Wheel load and rail model should be checked before installation.
- Lifting height and hook approach affect usable workspace.
- Duty class influences motor, brake and reducer selection.
- Electrical protection and limit logic should match the facility standard.
- Service platform, ladder and maintenance clearance should be planned early.
Data Needed for Quotation
- Rated load and duty class
- Bridge span and girder spacing
- Lifting height and hook approach requirement
- Trolley travel length and rail data
- Control method and safety requirements
