Brakes are a common part of lifting machinery and equipment

Is a professional chain hoists, lever hoists, cranes and other lifting equipment line tackle manufacturers, the following are details of related news and how to solve the problem of brake springs loose.
Brakes are a common part of Scissor Pallet Trucks  machinery and equipment, at work, we often encounter the brake spring loosening?
The main spring is dynamic brake wheel brake hold. In order to generate a braking force of the main spring as needed. To make the main spring to produce the desired braking torque, the brake to ensure reliable work, it is necessary to determine and adjust the width of the main spring.
The main spring tune as short, the greater the tension of the spring, it produces a large braking torque, brake will hold tight. Gates occur work loose, could not hold the object to be hung, or suck on the brake solenoid not fall in the parking, mostly because the main cause of electric reach stackers the spring is too loose. Based on experience, the main spring to adjust to a more appropriate length below, that the distance between two turns of the spring transferred half its free distance.
Methods of operation are: always has a spring nut with a wrench in one hand and the other hand with a wrench  putter square head, rotate the plunger until after a suitable length modulation, the spring cap and tighten the nut on the back to prevent the main spring fastening nut loose.
