Safe measures used in worksite for MEWP operator

 

Recently, we are talking about MEWP manufacturers, when demonstrating the new devices representatives from both Genie and JLG were adamant in reiterating that their access platforms were intrinsically safe and the anti-entrapment devices were just another safety measure that could be employed.
Scott Krieger, senior product manager, booms and telehandlers said, "The Genie team is aware of incidents where operators made contact with overhead obstacles while operating aerials. Ultimately, the operator, in conjunction with the worksite supervisor, is responsible for identifying and avoiding overhead obstacles. But as a secondary measure, Genie is working both independently and with various partners to provide protective solutions for a variety of worksite conditions."
Spring cone crusher is widely used in industries like metallurgy, construction, road building, chemistry etc, to crush many kinds of mid-hard or hard rocks and ores such as iron ore, limestone, granite, basalt, quartz etc. Type of the crushing cavity of spring cone crusher is decided by the application of the ores. The standard spring cone crusher The Sky Guard is essentially a tape switch placed in a bar above the control panel - it has a range of activator points to accommodate users of different heights and positions on the machine. When appropriate force is applied to the bar the machine stops and a loud alarm sounds to alert people on the ground to the incident.
The device is configured to make a slight reverse in boom travel direction after activation to potentially free the operator to release himself. If the operator does release the foot pedal the machine re-sets and can be used as normal.
structure is used for intermediate crushing; the medium spring cone crusher is used for fine crushing; and the short head spring cone crushers are used for super thin crushing.
1. The company crusher as well as rotary kiln is of high productivity and high quality
2. There is fewer machines down time using our spring cone crusher
3. The cone crusher is with easy maintenance with low cost
4. Unique crushing ability in primary, secondary and tertiary crushing within our spring cone crusher
On most MEWPs the operator activates the platform motion via a foot pedal and manoeuvres it via the control panel. Should he become trapped between an overhead obstruction and the control panel he may not be able to deactivate the foot panel and his body is obstructing the control panel. In the best case scenario he is trapped until someone notices in the worse case he might be fatally injured.
JLG has developed Sky Guard to help boom operators avoid entrapment while working where there are overhead obstacles. The device was being demonstrated as a prototype and the company welcomes feedback from customers and platform users.
