Hydraulic Drives

The drive is made up of a pawl and ratchet mechanism that is beneficial to convert rotary motion into unidirectional or linear motion. The pawl and ratchet mechanism is custom designed to change the unidirectional motion of the ratched into an oscillatory motion, between the teeth of the ratchet. This enables the shaft to rotate in a step by step way to control the linear motion of the travelling grate. The raw material entering into the boiler is fed from the top and by the time it reaches the travelling grate, it is completely burnt and the energy is consumed by the boiler. The leftover ash travels down to the travelling grate and the step by step rotation of the shaft allows it to be evenly distributed on the travelling grate and is carried away from the boiler

The travelling grate also is specially designed and developed to cater to the industries dealing with boiler applications to efficiently handle the ash being sent out of the boiler. It can be applied in the food processing industry, steel mills, sugar industry, paper industry and many such engineering verticals where boilers are used. The pulsating grate drive is similar in operation as compared to a travelling grate but it consists of a step design along with the grate. It is also used for similar applications as well as sorting out materials in certain cases. ii. Product Features: a. Drive designed for reverse motion of the travelling grate to prevent jamming b.
