Advantages of single girder overhead crane

Single girder overhead cranes are one of the most frequently used lifting crane for material handling. Single girder overhead has the following features and advantages:

On Steel frame fabrication of single girder overhead crane

• 1) The steel frame of the single girder overhead crane is made of Q235B material steel which is widely used, the used steel along with material report and qualified certificates.
• 2) The steel frame fabrication strictly follow national standard, main force weld line use double groove welding technique, all process with appearance inspection and nondestructive inspection, all welding engineer should be qualified with corresponding certificates.
• 3) Main girder of the single girder overhead crane is fabricated with complete plate. In other words, the crane girder is all plates without any joints, offering a solid foundation for the safety of the single girder overhead crane.
• 4) All plates for the production of the single girder overhead crane is processed with automatically cutting by CNC machine, preset camber.
• 5) Steel with sand blasting, standard follow GB8923 SA2.5, it can increase the painting adhesion, and ensure the long time good looking of single girder overhead crane.
• 6) Longitudinal waist weld of main beam by advanced automatic special plane welding, with good surface and very good welding quality.
• 7) End carriage fabricated by Rectangular tube, without any welding and joint.

On mechanical systems of single girder overhead crane

Lifting mechanism of the single girder overhead crane has the advantages of compact structure, light weight, small size, and convenient operation and so on.

• Gearbox. Single girder overhead crane with electric hoist reducer adopts helical gear three-stage gear, gear and gear shaft used 40Cr or 20CrMnTi steel forging processing, along with heat treatment, all with a rolling bearing, box shell made of cast iron manufacturing, assembly is close, dustproof and reliable
• Drum. The rolling drum of the single girder overhead crane is made of cast iron or seamless steel pipe, which is connected with the reducer and the other end is supported by a rolling bearing at the front end of the conical motor. The roll shell is made of steel plate.
• Hook. The hook of the single girder overhead crane is made of 20 steel forging, and is connected with a thrust ball bearing by hook beam and shell, the hook running freely.
• Coupling. The torque of the motor is transmitted to the speed reducer through the claw type elastic coupling, and the coupling can absorb the load shock to obtain a smooth start.
• Limit switch. To prevent faults caused due to hook up and down over the limit position, limiting device is arranged on the hoist, when the hook to the limit position, due to the single girder overhead crane drum device on the guide rope device drives the limit position controller action to automatically cut off power make the gourd to stop running.
• Motor. The starting torque of the motor with larger starting torque, in order to adapt to the frequent direct start of the product, the maximum torque is 2.4~3 times of the rated torque.
• To ensure the safe and reliable, all the electric hoist are equipped with a weight limiter.
• Electric control system. The single girder overhead crane control box and operation button box, is with pressure loss, interlock, overload, overload alarm, etc.

Trolley traveling mechanism of the single girder overhead crane

The single girder crane electric hoist running mechanism for the electric trolley type. Gear reduction gear for 40Cr forging, along with quenching and tempering treatment, installed in the closed reduction box, all of the rolling bearing support, wall plate manufacturing, to ensure that the operation is flexible, easy to use, long life. The running mechanism of the trolley is equipped with frequency converter, stepless speed regulation, stable running, accurate positioning and comfortable operation.

Traveling mechanism of the single girder overhead crane

Misconception on single girder overhead crane

Misconception: Single girder overhead crane is not as durable as double girder overhead crane when sharing same quality.

Truth: With properly design, a single girder overhead crane can be the perfect solution for lifting a light to medium duty crane. And also, single girder overhead crane is also perfect for a facility where headroom and/or floor space is limited.

Features of Single girder overhead crane

In order to provide you’re a better efficiency, Dongqi Single girder overhead crane has the following features:

• The single girder of the overhead crane is made of computer-optimised box sections.
• Torsionally rigid end carriages, and weld box-section design.
• Cost-effectiveness due to the long service lift of the electric hoist, the lifting system of the Single girder overhead crane.
• The increased lifting and cross-travel speeds improves the material handling efficiency.
• The variable cross-travel speeds enable the Single girder overhead crane low-sway during material handling.

Advantages vs. Disadvantages of single girder overhead crane

Comparing with double girder overhead crane, the single girder overhead crane has the following advantages and disavantages: 

Single girder overhead crane have lesser weight because

• 1. There is only one cross girder, the weight is lesser compared to 2 girders in double girder overhead cranes.
• 2. The hoisting mechanism is simple as it is a standard hoist, being modular weight of the Hoist is much lesser than its counterpart in double girder cranes.
• 3. The platform as in double girder overhead cranes is not feasible in Single girder overhead crane

Due to lower weight of the single girder eot crane,  the crane price is lower, the supporting structure i.e gantry girders, columns and overall building size can be reduced.

Disadvantage of single girder overhead crane

• Maintenance is difficult as there is no platform / accessibility.
• The lifting height is reduced compared to a similar double girder overhead crane

How Dongqi has conquered these above disadvantages

Dongqi is providing a maintenance platform on one edge of the single girder overhead crane.
The control panel is mounted on this maintenance platform. Hence is easily accessible and maintainable.

• 1. Also the construction of the platform is such that the electric hoist can be maintained from this platform.
• 2. Dongqi is offering Low head Room Hoist. Hence the disadvantage of single girder overhead crane is nullified as the height of the hoist is reduced and thereby the single girder overhead crane can offer heigher lifting height, comparing with the one with no low headroom hoist. 

Why single girder girder crane cannot be solution all the times?

• Dongqi has done single girders cranes upto 30t Capacity. Above this Single girder overhead crane are not recommended.
• Also the max span which we have done for Single girder overhead crane is 25M.
