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 top, low top, pointed top, 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, provides comfortable riding conditions for the occupants, and protects them from vibration, noise, exhaust gas during driving, and the impact of the harsh external 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 and 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 and 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. It should give people a sense of beauty and embellish people's living environment with its clear sculptural shape, elegant decorative parts and interior covering materials, and pleasing colors. 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 and driver's seats. In order to improve the driver's work efficiency, improve The driver's working conditions and the cab should meet the following requirements:
Ensure that the driver has a good view, and the equipment layout in the cab should not affect the view.
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. When there is dust or harmful gases, a closed cab with dust-proof and anti-virus devices should be used.
The cab must have reasonable lighting and a wooden or insulated rubber floor to provide the driver with a good, comfortable and safe working environment.
. Above the cab, the hatch leading to the carriage platform should be equipped with a safety device. When the hatch cover is closed, the crane can 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 cab of the small crane should not be less than that, and it can only be removed inward. A fire extinguisher and an electric bell alarm device should be installed indoors.
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 a comfortable operating environment. , convenient and satisfying human-machine engineering, which is conducive to operators operating 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 analysis, cab noise comes from engine transmission noise, chassis transmission noise, device noise, road noise and friction sound, etc. The noise reduction methods generally include: anti-vibration, sound insulation and sound absorption. Let me introduce to you three tips for reducing noise.
Anti-vibration: One is to prevent vibrations of large covering parts from low-frequency vibrations in a large range, and the other is to prevent vibrations from high-frequency vibrations 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. Higher vibration damping capacity can be obtained through the shear deformation of the middle layer, especially in areas close to the steel plate. This method is used on the cab coaming and floor on the engine side. Do not put sandwich bank cards together with electrical appliances with strong magnetic fields such as mobile phones, TVs, stereos, microwave ovens, etc. It is best to place them far away. Do not put multiple bank cards and passbooks together. There are two ways to construct components: one way is to add anti-vibration materials between punched steel plates and steel plates. Second, adhere a resin layer or asphalt-based anti-vibration plate to the steel plate. 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 penetrating, sound insulation materials are mainly used on the inner panel on the side of the cab near the engine. For the pores of hoses, wires, steering columns, etc. that pass through the cab, in order to prevent pores To prevent sound transmission, the area around the hole should be sealed. Do not put bank cards together with electrical appliances with strong magnetic fields such as mobile phones, TVs, stereos, microwave ovens, etc. It is best to put them far away. Do not put multiple bank cards and passbooks 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 capability is extremely reduced and needs to be installed in the cab floor. The middle layer uses synthetic foam 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. For 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 put bank cards in other places in the cab with electrical appliances with strong magnetic fields such as mobile phones, TVs, stereos, microwave ovens, etc. It is best to put them far away. Do not put multiple bank cards and passbooks together. The surface interior materials should not only consider aesthetics and sound insulation, but also have sound absorption properties. Sound-absorbing materials are mostly porous materials, such as fiberglass, foam plastics, blankets, etc. The above three noise reduction methods are currently commonly used by manufacturers. They are practical and feasible and fully meet the requirements for indoor noise and radiated noise required by EU directives.
