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，储能弹簧制动器并不相同。相反，由于储能弹簧驻车制动行程大于行车制动行程，储能弹簧也可用于在行驶制动力不足的情况下辅助紧急制动。因此，储能弹簧制动器不仅可以用作驻车制动器，还可以用作紧急制动器。因此，在制动稳定性和性方面，空气制动器制动系统优于普通空气制动器。

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，液压制动结构简单，安装空间小，只需制动主缸，辅助泵，油杯和连接管，无需其他辅助设备;除制动主缸，辅助泵和制动器外，空气制动器复杂。还有空气泵，储气罐，高压控制器，继动阀等需要较大安装空间和结构复杂的部件。为确保，后制动缸现在是一个气体制动器。

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，传统的制动器是手动制动器，其锁定驱动轴。当施加制动时，压缩空气进入制动通风系统以锁定车轮。当手制动器或驱动轴机械故障时，手制动器失灵;当气泵，管道，油箱或制动阀的任何部分发生故障时，脚制动器失效。空气制动器可以有效地避免这些危险。

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，空气制动器的制动室有一个强大的弹簧。压缩空气会在行驶时抬起弹簧。手制动器是让空气流出并让弹簧锁定制动器。当车辆中的气压太低时，还产生制动效果以确保性。

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.
