1. The parking brake of ordinary air brake can only be used when the forklift is stationary, because its braking torque acts on the drive shaft. If it is used in the self loading mixer, it is easy to cause damage to the drive shaft and rear axle. Serious overload, or possibly due to the locking of the differential case, causes the opposite rotation direction of the left and right wheels, which causes the self loading mixer to close or even rotate when braking.

但是，儲能彈簧制動器并不相同。相反，由于儲能彈簧駐車制動行程大于行車制動行程，儲能彈簧也可用于在行駛制動力不足的情況下輔助緊急制動。因此，儲能彈簧制動器不僅可以用作駐車制動器，還可以用作緊急制動器。因此，在制動穩(wěn)定性和安全性方面，空氣制動器制動系統(tǒng)優(yōu)于普通空氣制動器。

However, the energy storage spring brake is not the same. On the contrary, since the parking brake stroke of the energy storage spring is greater than the service brake stroke, the energy storage spring can also be used to assist the emergency braking in case of insufficient driving braking force. Therefore, the energy storage spring brake can be used not only as a parking brake, but also as an emergency brake. Therefore, in terms of braking stability and safety, air brake braking system is better than ordinary air brake.

2，液壓制動結(jié)構(gòu)簡單，安裝空間小，只需制動主缸，輔助泵，油杯和連接管，無需其他輔助設(shè)備;除制動主缸，輔助泵和制動器外，空氣制動器復(fù)雜。還有空氣泵，儲氣罐，高壓控制器，繼動閥等需要較大安裝空間和結(jié)構(gòu)復(fù)雜的部件。為確保安全，后制動缸現(xiàn)在是一個氣體制動器。

2. The hydraulic brake has simple structure and small installation space. It only needs the brake master cylinder, auxiliary pump, oil cup and connecting pipe, without other auxiliary equipment; In addition to the brake master cylinder, auxiliary pump and brake, the air brake is complex. There are also air pump, air tank, high pressure controller, relay valve and other components that need large installation space and complex structure. For safety, the rear brake cylinder is now a gas brake.

3，傳統(tǒng)的制動器是手動制動器，其鎖定驅(qū)動軸。當(dāng)施加制動時，壓縮空氣進入制動通風(fēng)系統(tǒng)以鎖定車輪。當(dāng)手制動器或驅(qū)動軸機械故障時，手制動器失靈;當(dāng)氣泵，管道，油箱或制動閥的任何部分發(fā)生故障時，腳制動器失效。空氣制動器可以有效地避免這些危險。

3. The traditional brake is a manual brake, which locks the drive shaft. When the brake is applied, compressed air enters the brake ventilation system to lock the wheels. When the hand brake or drive shaft mechanical failure, hand brake failure; When any part of the air pump, pipe, oil tank or brake valve fails, the foot brake fails. Air brake can effectively avoid these dangers.

4，空氣制動器的制動室有一個強大的彈簧。壓縮空氣會在行駛時抬起彈簧。手制動器是讓空氣流出并讓彈簧鎖定制動器。當(dāng)車輛中的氣壓太低時，還產(chǎn)生制動效果以確保安全性。

4. The brake chamber of the air brake has a strong spring. Compressed air will lift the spring while driving. The handbrake is to let the air out and let the spring lock the brake. When the air pressure in the vehicle is too low, it also produces braking effect to ensure safety.
