Full-life impact-resistant, vibration- and noise-reducing telescopic device
Description
It is mainly composed of double S-shaped panel steel, vertical plates, stainless steel U-shaped drainage channels, anchor plates and anchor rings.
◆All-steel structure with long service life: The telescopic device adopts an all-steel structure with no rubber parts to avoid rubber aging defects. It is durable in use, has strong vitality, and achieves a full lifespan;
◆Good impact resistance: using double S-shaped steel, the wheels do not pass through the telescopic device at the same time, forming an oblique movement of the wheel and the telescopic device, reducing the direct impact of the vehicle on the telescopic device (the impact force can be reduced by up to 50%), improving the Durability of product structure and driving comfort;
◆Good noise reduction effect: Actual measurement shows that compared with the straight-slit type telescopic device, the full-life impact-resistant and noise-reducing telescopic device reduces noise by about 10 decibels, and the noise reduction effect is good;
◆Blocking and absorption: The bottom is designed with a sound-insulating stainless steel drainage channel to block the transmission path of noise to the bottom and avoid the concentration effect of noise;
◆Low cost: simple structure, no wearing parts, low maintenance cost during the maintenance period;
◆The installation accuracy is easy to control: it can overcome the defects left by the bridge construction unit's failure to comply with the specifications (such as irregular notches, different depths, etc.), and the accuracy is easy to control.
◆Beautiful appearance: a straight line is replaced by a straight line, and the double S resembles auspicious clouds. It is graceful and has a good meaning.
