Sany recently introduced the new Sany C6 Crawler Cab for its telescopic crawler range. Based on the operator’s experience, the cab features the latest ergonomic designs meeting global safety standards.
When developing its new Sany C6 Crawler Cab for its range of telescopic crawlers, Sany wanted to find a way to distinguish its company, and its crawler cranes, from other manufacturers in the global marketplace. Sany also wanted to provide a functional and better working environment for the operator. To achieve this goal, Sany developed a new operator cab designed to enhance the operator’s experience with the crane.
Along with a better operating experience, Sany also wanted its new C6 Crawler Crane Cab to have a unique appearance compared to its competitors. The new cab features a more rounded design, similar to the shape of a helicopter, compared with previous cabs which tended to be more square in appearance. With this more rounded shape Sany was able to incorporate windows larger than it normally uses to achieve one of its main goals – improved visibility.
Achieving better visibility
The cab has been lengthened by 100mm, and the seat and armrests are rearranged to improve elbow room by 10 per cent; door space is up by 50 per cent, and a large glass area has been adopted, and the width of the cross beam is reduced from 80mm to 73mm. With these changes the operators’ field of view range is increased by 33 per cent.
On an average crawler crane, visibility from the left side of the operator cab is more difficult because the cab is positioned on the right side of the lifting apparatus. By shying away from its typical cab design, Sany has been able to improve operator visibility on the left side because of the increased surface area of glass.
Placement of the displays within the cab was an important factor in increasing visibility for the operator, as well. While Sany wanted operators to be able to see all the displays easily, it didn’t want them distracting from the operator’s view outside of the cab and inhibiting productivity. All of the screens necessary for crane operation—the camera screens, Load Moment Indicator (LMI) screens and crane functionality screens—have been placed in the same location, just below the operator’s direct line of sight.
This enables the operator to easily see what’s going on outside the cab, yet still have the various display screens readily visible within the operators’ peripheral view. Operators can see the operation of the winches and other components on the crane and also see behind the crane.
All new non-linear curved industrial design on the C6 Cab creates a modern look. The cab features a one-piece handrail and removable roof guard and the interior trim has been upgraded.
The sliding door adopts a curved track when closing to provide perfect thermal and acoustic insulation while sheet metal has been adopted for the main structure – and this is verified by Fine Element Analysis (FEA) at various extreme conditions. The structural strength is well suited to tough work sites. The cab’s roof guard features a high density removable lattice fence which blocks out falling objects from heights and conforms to EN13000 standard.
The front windshield can be opened by 70 degrees, providing better ventilation and a second emergency exit.
The new cab features mechanical suspension and shock absorption, and with a 20 per cent larger surface area the seat can be adjusted in multiple ways for a comfortable operator experience. Adjustment in headrest by six levels, backrest angle, cushion extension, cushion inclination, mechanical suspension, weight adaptation and armrest box and seat position are all included in the new cab.
Operator comfort
Automobile style pedals are ergonomically designed and the highly efficient 5kW Denso air conditioner features five different modes via one-key switch. Airflow is distributed from six vents, creating a next level experience of comfort for the operator.
Sunshades on four sides of the cab are manually controlled and help improve air temperature for a more comfortable working environment and the electrically controlled fan improves indoor air circulation.
The functions of the 25.5cm Smart LMI dual split screen include visual fault self-diagnosis, Bluetooth phone and audio, power-on password and facial recognition. It also features video storage and export capabilities, making operation more comfortable and easier. 3×3 monitoring images, full screen display and a zoom-in function is available for every single image.
Simple User Interface (SUI) design ensures the bionic symbol display is simple and clear. The user interface has no more than three levels, making data reading convenient and quick. A 3-level fault alarm and diagnosis ensures troubleshooting proceeds smoothly and a hidden menu is designed to make full use of screen space. The smart-phone-like operation of the touch screen supports finger swiping, ensuring it is easy to operate.
Integrated display keys and a navigation knob are designed to realise all auxiliary operations and the cab features a one-key start and stop, automatic engine idling and flameout (AIS), with eco mode available, ensuring the operation of Sany the crawler crane range is more fuel-efficient.
