GBCRANES CHS series single girder overhead cranes feature maximum rigidity for a minimum deadweight. This keeps the load on the crane runway to a minimum – and a cost-effective design can be selected for the building. This approach provides you with a cost-effective solution.
1. Design is based on FEM and CMAA70 standards.
2. With optimizing design and low headroom, the crane height is greatly reduced, to achieve higher lifting height under the same plant height.
3. With optimizing design and low wheel pressure, the crane height is greatly reduced, to achieve greater lifting capacity weight under the same strength of the workshop.
4. Crane girders made of computer-optimised box sections.
5. End carriages of torsionally rigid, welded box-section design.
6. Wheel group with adjustable structure, to prevent the rail from gnawing.
7. Crane is controlled by Three-In-One mechanism with frequency conversion, to reduce the equipment noise.
8. Overload limiter, height limiter, Stroke limiter, photoelectric limiter and other security measures are equipped according to different working conditions, crane black box with recorded analysis functions can be added based on the customer requirements.
9. Lifting capacity: 1~20 t, non-standard customized crane can be produced.
Personalized configuration
Optimum integration into existing and new buildings.
Control pendant suspended for separate travel on the crane girder with display for installation monitoring.
Radio control with display and proportional pushbuttons possible (optional).
Optional radio control with power and signal transmission via energy chain system.
CMAA standard
Class A – This denotes standby or infrequent usage, such as cranes found in power utilities or motor rooms, where precise handling of equipment at slow speeds with long idle periods between lifts occurs.
Class B – This denotes light service, such as cranes used in repair shops or light warehousing, at slow speeds, with up to five lifts per hour up to maximum rated capacity.
Class C – This is for moderate service, such as those cranes installed in machine shops, including handling an average of 50% of the rated capacity up to 10 times per hour.
Class D – This is for denoting heavy service, such as cranes deployed in heavy machine shops, foundries, container yards, and more, where loads of 50% of the rated capacity are handled constantly.
Class E – This is for severe service, such as cranes found in scrap yards, cement mills, lumber mills, and more, where the crane makes 20 or more lifts per hour at or near its rated capacity.
Class F – This denotes continuous severe service, including custom-designed specialty cranes, that handle loads approaching the maximum rated capacity non-stop under extreme conditions.
