Small crane cab is not only the driver's workplace but also an important part of the entire vehicle. A general cab includes windows, doors, cockpit, etc. The cab shapes include high roof, low roof, pointed roof, etc. The cab is one of the most important parts of the car, and its design will directly affect the performance and safety of the car. The cab provides convenient working conditions for the driver and comfortable riding conditions for the passengers, protecting them from vibrations, noise and exhaust gases when the car is driving, as well as the impact of the harsh outside weather. Some structural measures and equipment on the car cab also contribute to safe driving and reduce the consequences of accidents. The cab should ensure that the car has a reasonable external shape that can effectively guide the surrounding airflow when the car is driving to reduce air resistance and fuel consumption. In addition, the cab should also help improve the driving stability of the car, improve the cooling conditions of the engine, and ensure good ventilation inside the body. The car cab is also an exquisite comprehensive work of art that should embellish people's living environment with its clear sculpture shape, elegant decorative parts and interior covering materials, and pleasant colors to give people a sense of beauty
1. Requirements for the crane cab
The crane cab is a studio where the driver operates the crane. It is equipped with controllers, control panels, switchboards, driver's seats, etc. The driver improves the driver's work efficiency in order to improve the work efficiency. The working conditions of the cab should meet the following requirements:
Ensure that the driver has good vision. The equipment layout in the cab should not affect the vision.
The joystick or handle (wheel) of the controller should be as accurate, reliable, convenient and labor-saving as possible.
. Crane cabs operating in high-temperature or cold environments should have prevention and heating measures. If there is dust or harmful gases, a closed cab with dust-proof and anti-virus devices should be used.
The cab should have reasonable lighting and a wooden or insulating rubber floor to provide the driver with a good, comfortable and safe working environment.
. The hatch above the cab leading to the carriage platform should be equipped with a safety device. Only when the hatch cover is closed can the crane be powered on and started.
The door of the cab should be designed to open inward or push aside. A safety device should be installed on the door. The crane can only be powered on and started when the door is closed.
The thickness of the glass installed in the small crane cab should not be less than that and can only be removed inward. A fire extinguisher and electric bell alarm device should be installed in the room.
2. Noise reduction tips for small crane cabs
The small crane cab is a space for operators and activities. In addition to having a good view, sufficient stiffness and strength, it must also ensure that the operating environment is comfortable, convenient and satisfying. The ergonomic engineering helps operators operate efficiently and reliably. The sound insulation and noise reduction capabilities of the cab directly affect the operator's comfort and labor efficiency. According to relevant data, cab noise comes from engine transmission noise, chassis transmission noise, device noise, road noise and friction noise, etc. The approaches are roughly: anti-vibration, sound insulation and sound absorption. Let me introduce to you three tips for reducing noise.
Anti-vibration: One is to prevent vibration of large covering parts from low-frequency vibration in a large range. The other is to prevent vibration from high-frequency vibration in a small range. For the former, measures can be taken to change the curvature, increase the drawbead, and increase the rigidity of the cover. The latter can improve the vibration damping capacity by using anti-vibration materials. A common method is to add a sandwich structure of anti-vibration materials between steel plates. Through the shear deformation of the middle layer, a higher vibration damping capacity can be obtained, especially near the engine side. This method is used on the cab coaming and floor. Appliances with strong magnetic fields such as mobile phones, TVs, stereos, and microwave ovens should be placed far away from each other. There are two ways to construct components: one way is to add anti-vibration material between the punched steel plates and the steel plates; Install appropriate elastic elements and damping elements between the cab and the chassis to reduce the vibration of the cab structure and the accompanying secondary noise.
Sound insulation 1. In order to prevent engine noise from passing through, mainly use sound insulation materials on the inner panel on the side of the cab near the engine to prevent sound transmission in the pores of hoses, wires, steering columns, etc. that pass through the cab. Seal around the hole. Do not place them together with electrical appliances with strong magnetic fields such as mobile phones, TVs, stereos, microwave ovens, etc. Do not place them far away and do not place them together.
Sound insulation 2. The driving noise on the road and the noise from the engine exhaust device are mainly transmitted through the cab floor. Therefore, the floor should adopt a double-wall structure. The middle air layer can act as a spring. The sound insulation ability is extremely reduced and synthetic foam must be used in the middle layer. Material or skin anti-vibration material. Sound absorption is the use of materials and structures that can absorb sound energy to absorb part of the sound energy in the noise propagation path to reduce the noise reaching the operator. To deal with engine noise, add fiberglass, blanket, and foam sound-absorbing materials to the coaming on the side of the cab near the engine and inside the engine hood, and adjust the sound-absorbing intensity and characteristics according to the thickness and density of the material. Do not place the other parts of the cab far away from electrical appliances with strong magnetic fields such as mobile phones, TVs, stereos, microwave ovens, etc. The interior materials on the surface should not only consider aesthetics and sound insulation, but also have sound-absorbing properties. Sound-absorbing materials are mostly porous materials such as fiberglass, foam plastics, blankets, etc. The above three noise reduction methods are practical and feasible noise reduction methods commonly used by various manufacturers and fully meet the requirements of indoor noise and radiated noise required by the EU directive.
