What is a Single Girder Crane?

A single girder crane is a type of overhead crane with one main bridge or beam on which hoisting equipment can travel along to the precise position required to lift and/or lower the load.

Unlike a runway beam which is fixed in one place the bridge/main beam on a single girder crane can travel, this is due to the fact that it has two end carriages which incorporate motor driven wheels which enable the bridge to travel along the supporting steel work fixed to the building structure.

What lifting applications are they best suited to?

This type of overhead crane only has one girder/bridge unlike a double girder crane which has two, and so therefore is ideal for lighter loads, usually up to around 25 tonne. Typically used by steel stock holders to handle large steel sections; they are also commonly found in machine shops and large storage facilities to enable quick and easy handling of large and awkward loads.

The Single Girder Cranes we offer

Cranes Direct can offer two main types of single girder crane, the LX for lighter applications with SWLs up to 5 tonne and the ZX with SWLs up to 25 tonne.

These cranes are lighter in weight than double girder cranes and therefore will often require lighter & smaller steel framework/gantry system. This can greatly reduce cost and space. We generally supply our single girder crane systems complete with an electric hoisting system. They are designed to work together with the crane for optimum effectiveness. They provide smooth operation, low maintenance, cost effectiveness and maximising the use of the production area.

These cranes are operated from a touch button control pendant or a radio controlled hand set. These will both drive the crane and the hoist.

The single girder crane can be top running systems or under slung from tracks which are already present as part of the buildings roofing structure. Under slung cranes remove the need for support columns and so free up valuable floor space.

The Hoist

The uniquely designed electrically powered hoist we supply specifically with these single girder crane systems boast many benefits. There are no external trolley or hoist gears ensuring they provide a longer working life than those with external gearing. Long life guide rollers are used which eliminate wear on the beam flanges and also remove the need for wheel flanges which can be a large wear part on other hoists.

There is no need for a counter weight due to the reaction roller which improves traction and control. Other benefits include; disc brake system for high control braking; extra load security – will always hold the load even if power fails.

There is also a choice of crane travel control –

1) Two speed motor, soft start, inertia fly wheels, auto timer control (slow through to fast) precise control.

2) Smart-drive, sensor-less current vector controlling system with – condition monitoring, LED diagnostics, removable memory board and fully programmable speeds, acceleration and deceleration.

Intended Use

These single girder cranes together with their hoisting system are intended to be used for lifting, lowering and moving loads. They are not designed to transport people. Loads that are handled should never exceed the stated capacity of the crane and hoist. Modifications should never be made without prior approval as this could affect the safety of the equipment.

This crane and hoist combination should not be used for pulling objects at an angle. Nor should they be used for dragging loads along the ground. All loads should be lifted and lowered in a vertical plane.

The crane will be clearly marked with a safe working load. This should never be exceeded. The weight of any lifting equipment used, including the hoist should also be taken into consideration as well as the load its self.

The end travel limiters are safety devices and should not be used as a regular stopping method.

Important Daily Checks

Just like when using any other lifting equipment a daily pre-use check over is essential to ensure optimum safety and prevent accidents.

Basic Things to Check

Check for any hazardous objects which could be in the cranes movement path

Check all wire ropes are seated accurately in drums and sheaves

Rope should be sound, and have no kinks or broken wires.

The hook’s safety catch must be checked to ensure it engages correctly.

Check all warning signals are operational, audible or visual.

Check limit switches by  carefully lifting and lowering the hook (empty)  to maximum positions. Upper limit switch failure can cause damage to the hoist

Check all travel operations and functions.

Check Hoist braking system.

Always ensure the crane operator is sufficiently trained and confident in all crane and hoist operations. The crane operator and others involved in the lifting application should have an agreed signalling code to ensure the operator can stop the crane quickly, of make small positional adjustments if necessary.

If you need to discuss your craning requirements please give our team a call where we can discuss your needs in more depth and arrange site visits if necessary.

Remember we have our own engineers who can install, repair and service all types of cranes including the single girder crane system. Lifting equipment is also covered as well as offering thorough inspections with all the relevant paperwork you will need for your records.

Thorough inspections are a legal requirement to ensure your lifting equipment remains in safe working condition. Cranes Direct can accommodate your entire crane and lifting needs, contact us today.

The hoisting systems to compliment these cranes boast a wide range of features to work seamlessly with your chosen crane system, they com in many different formats to fit the various crane types but the basic operation specifications are the same.
