Ten backhoe loaders were made available immediately to the Nepalese Army and are now at work in the areas worst hit by the disaster, which has left more than 5,000 people dead and 10,000 injured.
"It is shocking to see the devastation caused by this earthquake and the resulting widespread damage and destruction," said JCB Chairman Lord Bamford. "On behalf of JCB, I express my heartfelt condolences to everyone affected by this natural disaster. JCB will continue to help the Nepalese government in every possible way."
JCB supplied the backhoes through its dealer, MAW Enterprises Pvt Ltd, in Nepal. The electrical power generators are also en route from JCB India's factory in Delhi to help stricken communities caught up in the quake.
The JCB backhoe-loaders have been deployed to help ground relief efforts in the aftermath of the earthquake, which measured 7.8 on the Richter Scale. In the coming weeks and months, the donated machines will be used in reconstruction efforts.
