This invention relates with the development of a simple device at Central Plantation Crops Research Institute (CPCRI) by scientists of Central Institute of Agricultural Engineering (CIAE), Bhopal. Safety attachment is required for the climbers climbing on tall palms. Harvesting and crown operation are carried out at about 15 m height from the ground. Presently, Coconut growing states are facing acute shortage of traditional climbers. Coconut Development Board (CDB) is promoting locally available devices by providing training to the youths of Kerala with the assistance of KVKs and other organizations. These devices are fast but not having any safety arrangement in case of slipping from the device, the climber is not safe. Now a day, youths who want to adopt harvesting or climbing as a profession not having experience of traditional harvesting or climbing having height phobia. This concept of safety is also reduces the height fear /height phobia and eliminate the risk of falling down. This safety features will attract more youngsters towards adoption of coconut climbing devices for harvesting of coconut as a profession for earning their livelihood. The device consists of an attachment to the climbing device, which positively locks the climbing machine to the coconut tree if the climber looses balance and slips as it is attached to the body harness worn by the climber. A positive locking device in the machine at very close interval is required. The climber will hang secured in the body harness and regain his/her position in a few second without assistance of any other person. The attachment provides full safety to the climber during climbing and harvesting operations, which helps in reducing fear and increase efficiency/capacity. The safety attachment can be incorporated with the coconut climbing devices with simple modification/ refinement.
