Components

1
Main girders
Two box girders that carry the load. Welded to order from deflection and stress calculations; the section grows with the span.
2
End carriages
Wheeled assemblies that carry the bridge along the runway. The girders are bolted or welded to them.
3
Crab (trolley)
Runs on rails on top of the girders. The hoisting motor, gearbox, drum and brake sit on it.
4
Bridge travel drive
A geared motor on each end carriage. An inverter gives smooth starts and stops.
5
Runway
The beam and rail on columns or corbels. The bridge travels along it.
6
Service platform and handrail
A walkway along the girder for safe access to the drives, panel and crab.
7
Power feed
A festoon cable line or enclosed conductor bar that feeds power and control signals to the crab.
8
Hook block
Sheave block with a DIN hook. The hook rises between the two girders, which gives a high lifting height.
9
Control panel and controls
Contactor and inverter panel. The crane is operated by pendant or radio remote.

General features

The crab runs on top of the girders and the hook rises between them, so the same roof height gives more lifting height than a single girder crane.
The load is shared by two girders, which keeps deflection low at high capacities and long spans.
The service platform lets the drives, panel and crab be maintained in place, without scaffolding.
Equipment such as an auxiliary hook, dual speed, weighing and anti-sway can be added to the crab.
Suited to multi-shift operation and heavy duty classes.

Dimension letters

S: SpanDistance between the centre lines of the two runway rails.
A: WheelbaseDistance between the two wheels of an end carriage; it sets the stability of the bridge on the rail.
H: Lifting heightUsable distance from the highest hook position down to the floor.
C: Hook approach (top)Difference between top of rail and the highest hook position.
D: Crane build heightFrom top of rail to the highest point of the crane; it gives the clearance needed under the roof.
E: Hook approach (side)The closest the hook can get to the rail centre line; it sets the dead zone along the wall.

From order to installation

How an overhead crane comes to life

The seven steps a crane goes through, from first contact to handover.

01
Enquiry and site survey
Capacity, span, lifting height and duty are discussed; the bay is measured on site and the runway and columns are checked.
02
Quotation and order
A technical specification and quotation are prepared from the measurements. On approval the order is confirmed and delivery is planned.
03
Engineering
Girder section, wheel loads and duty class are calculated; fabrication drawings and the electrical design are produced.
04
Fabrication
Plates are cut, the box girder and end carriages are welded; wheel groups, trolley and hoist unit are prepared.
05
Painting and factory test
Surfaces are prepared and painted. Panel, motors and drives are wired; motions and safety equipment are tested at the factory.
06
Dispatch
Bridge, end carriages and trolley are split into transportable parts, secured and sent to site.
07
Installation and commissioning
The bridge is set on the runway, power supply and controls are connected. A load test is carried out, operators are trained and the crane is handed over.

Description

Applications and features

What is a double girder overhead crane?

A double girder overhead crane is a crane with a lifting trolley (crane trolley hoist) running on top of two main girders. Because the hook rises between the girders, it lifts higher under the same roof. It is built to order from 5 to 40 tons for high strength, stability and long service life in heavy industry.

Why a double girder overhead crane?

Compared with single girder systems:

High load capacity: suited to heavy loads.
Stable operation on wide spans: works over wider spans.
Greater lifting height: the hook rises between the girders.
Designed for heavy duty classes and long service life.
Walkway: a maintenance walkway and handrail can be added on the girders.

Areas of use

Heavy industry plants
Steel and metal production factories
Power plants
Machine manufacturing plants
Port and terminal applications
Large warehouses and logistics centres

Double girder crane components

Two box girders: with the rails the trolley runs on.
End carriages: at both ends of the bridge, travelling on the runway with their wheels and drive motors.
Crane trolley hoist: lifting trolley with drum, gearbox, motor and hook block.
Runway: girder and rail resting on columns or corbels.
Power and controls: busbar or cable power supply, control panel, pendant or remote control.
Safety: limit switches, overload protection and emergency stop.

Options

Inverter / PLC speed control and automation
Auxiliary hook (second hoist trolley)
Walkway and handrail on the girders
Radio remote control or operator cabin
Equipment suited to ambient conditions

Double girder crane prices

Double girder crane prices depend on:

Capacity
Bridge span
Lifting height
Duty class
Level of automation
Ambient conditions

You can request a free site survey and technical analysis for a firm price.

When choosing

Capacity: add the weight of the hook, slings and attachments to the heaviest load; mention any expected capacity increase.
Bridge span: the distance between the centres of the two runway rails (standard 6 – 40 m).
Lifting height: the highest point the hook must reach and the clear height of the bay.
Auxiliary hook: is a second lifting point needed next to the main hook?
Intensity of use: continuous operation through the shift sets the duty class and components.

Frequently asked questions

How many tons does a double girder overhead crane lift?

Standard systems are built from 5 to 40 tons. Higher capacities can be engineered for the project.

How does it differ from a single girder crane?

Double girder systems are designed for heavier loads and wider spans; they are stronger and more stable, and lift higher under the same roof.

What is the maintenance interval?

Maintenance is recommended every 3–6 months depending on use. In addition, lifting equipment must legally be inspected at least once a year.

What information is needed for a quotation?

Capacity, bridge span, bay length, lifting height, need for an auxiliary hook, whether there is a runway, intensity of use and site location.
