Davit Crane for simple
down-hole handling!
The new Davit Crane has been developed by Penny Hydraulics to make it easier and safer for utility and ground engineers to handle heavy items such as pumps up and down access shafts
at remote sites. The unit is designed to replace traditional lifting tools such as block and tackle
and eliminate manual handling. Light weight, robust construction and ease of use combine to
provide users with a versatile and effective load handling tool.
Penny Hydraulics responded to a request from one of the UK’s major utility businesses for a simple, effective and reliable solution for lifting and lowering sewage pumps in and out of deep access shafts. The customer’s existing block and tackle davit equipment was proving to be unreliable and prone to damage under load. It also required engineers to complete each lift in stages by hand which was tiring, cumbersome and inefficient. Although the customer has vehicle mounted cranes it is not always possible to use these if the access shaft is in a difficult position. Penny Hydraulics’ new, portable crane offers an ideal solution.
Penny Hydraulics developed the Davit Crane to be lightweight and portable. It is manufactured in two pieces from durable aluminium for the best possible combination of low weight and high strength. The whole crane, including winch, weighs 47kg when fully assembled. The unit is mounted into an existing socket adjacent to the access shaft and can be disassembled for easy carrying and transport when not in use. The largest sub-assembly weighs just 24kg, which means all components can be carried within the existing manual handling regulations.
The Davit Crane incorporates a powerful electric winch mounted at the end of the longer boom which allows loads of up to 500kg to be lowered as much as 16m (50ft) below ground level. Power is supplied from any vehicle using jump leads or a standard electric service socket. A wander lead enables remote control so that operatives can stand clear of moving parts during lifting operations for the best possible safety.
