机械式门封，又称为拉簧张紧可伸缩式门罩，主体由铝合金型材组成，配合拉簧张紧装置，正面采用加厚pvc耐磨板，侧面采用强韧pvc帘布，耐磨耐挤压，防水防紫外线，耐候性强。
高点机械式门封主要适用于一般装卸货区域，厢式货车需要在装卸货口进行装卸货作业时，车辆倒入具有防撞块的装卸货口，车辆后门打开后与机械式工业门封紧贴在一起，这个时候拉簧张紧装置发挥作用，将门封正面与车辆车厢后门紧紧贴合，正面的帘板将车厢罩入，形成临时封闭式货物搬运通道，保证仓库或成品库中的货物在相对密闭的环境中完成装车或卸货。
机械式门封结构特点
1.可伸缩框架设计：边框采用铰链式连接，具有可积压性，当车靠近后，保证了必要的柔软灵活性;
2.顶部排水系统：门罩顶部框架的顶部呈倾斜面，以便于顶部排水；
3.钢制保护装置：为保护装卸货物和门罩免受来自装卸货过程中的碰撞，减少维修，增加了钢制保护装置；
4.底部护角垫：底部护角垫保证门罩门帘处于竖直状态，同时确保了更好的密封性能；
5.坚固的框架结构：有效防止侧面框架在重压下向外张开；
6.多种规格尺寸：门罩可设计成多种规格尺寸，适用于所有型号、各种吨位的重型货车；
产品英文详情介绍
mechanical door seal, also known as a tension spring tensioned telescopic door cover, a body composed of aluminum alloy, with a tension spring tensioning means, the front wear plate thickening pvc, pvc side using tough cord, wear extrusion resistance, waterproof uv, weathering resistance. when high mechanical door seal mainly used in loading and unloading ships region, van cargo-handling operations required in the loading and unloading opening, is poured into a vehicle collision block loading and unloading port, the vehicle rear door is opened with the mechanical seal industrial doors close together, this time the role of a tension spring tensioning means, with the front door closed tightly bonded to the rear door of the vehicle cabin, the front flap will cover the compartment, forming a temporary enclosed cargo handling path, to ensure that finished products in a warehouse or the completion of loading or unloading goods in a relatively closed environment. mechanical door seal structure design features 1. telescopic frame: frame with a hinged connection, having a backlog of, when the car is close to ensure the necessary flexibility, softness; 2. drainage system top: top of the housing as a top of the door frame inclined surface, so as to drain the top; 3. steel protection: to protect the cover against the door and loading and unloading from a loading and unloading during a collision, reduce maintenance, increase of the steel protection; 4. corner pad bottom: bottom corner pad ensure housing door curtain in a vertical state, while ensuring a better sealing performance; 5. rigid frame structure: prevent the side frames under the weight of outwardly flared; 6. plurality size: door cover it can be designed into a variety of standard size for all models, various tonnage of heavy goods vehicles;
