Good Practice: Taking Loader Air Drain Valve Outside
Date: 26 Mar, 2018
How to pull the drain valve without ergonomic hazards?
Can feeder processes be safer and simpler?
Can there be a consistent solution?
In Readymix business wheel loaders are used for feeding the raw materials to the hopper through the Aggregate conveyors. A standard checklist was provided to the operator to check the loader daily before starting the machine. One of the activities in the check list was draining the air and water from the air tank
which is located below the loader rear side.
For carrying out this activity the major pain points were:
– the operator has to go under the loader to pull the drain valve
– ergonomics hazards are involved in the process
– approaching the valve itself was very difficult and not as per safety standard.
Our Ready Mix Solution:
To overcome thees problems, the team from RMX Jogeshwari plant obtained a simple and easy way to drain the air and water from outside of the loader. An extension unit was fixed on the air tank valve and the pipe was taken outside the loader near rear tyres. The unit which has been fixed has an elbow, barrel nipple
and brass ball valve. By using this method the air can be drained from the outside of the loader by operating the ball valve which was provided at end of the unit. No need to go under the loader. It was the safest method and will reduce the checking time as well. Anyone can easily approach the air drain point
of tank without going under the loader.
Currently this practice has been started in Mumbai commercial area. In future the team is planning to install the same at all other plants across India.
