Davit systems are commonly used to raise, lower, and suspend personnel performing routine maintenance inside confined spaces such as vaults, manholes, and pump stations.  Davits take two main forms:  portable davit arm systems, which feature wheels, and permanent davit arm systems, which attach to the floor.  Diversified Fall Protection has engineered a new product called the Portable Davit Base which offers the portability found in portable systems combined with a secure connection associated with permanent davit installations.
