The aluminum alloy hand pulls the gourd is a light and small lifting equipment. Although the aluminum alloy hand pulls the gourd, although the brake is sensitive, it also requires our careful inspection and maintenance to ensure that its performance is not affected. For example: If the oil droplets are dripped between the friction tablet and the spiny wheels, it will reduce the friction coefficient and reduce the braking performance. A good brake performance of aluminum alloy handle can help us complete the hanging operation very well. We should pay attention to the maintenance and use of brakes to prevent the performance from being damaged and affect our future work.
