The Spencer basket stretcher Shell, due to its robust form, has been studied to confront the most difficult emergency situations and is ideal for rescue operations in mines, at altitude and in water. Twin Shell is similar to the Shell stretcher; however, it can be divided transversally in half to improve storage and transport. To ensure perfect hold, four nylon cones and a security system protected by a protuberance have been inserted in the mound. Its specifications are as follows:- Length: 2150 mm [84.64 in] Divided length: 1180 mm [46.45 in] Width: 640 mm [25.19 in] Height: 190 mm [7.48 in] Load capacity: 280 kg [617 lbs] Weight: 17 kg [37 lbs]
