Of interest is the Type H Bomb Trolley also used with different adapters for the 22,000 pound bomb Grand Slam.
The trolley has rear wheel steering and hydraulic brakes. A bucket seat at the rear allowed an operator to cling on and operate brakes and steering.
The lifting cradle has a 4000 pound capacity bomb hoist on each corner. These consisted of a winding mechanism and a wire steel flexible cable wound around an internal drum. The mechanism was low geared with a planetary system internally so many turns of the handle had to be made to wind in the cable and lift the bomb.
Post war, some bright spark, seeing a surplus of 2000 and 4000 pound capacity bomb hoists decided to adopt them for installing and removing engines from the HP Victor aircraft. The engine tradesmen, being wimps, had bolt-on electrical motors with octopus umbilical s to plug into adjacent electrical supplies but the poor old armourer still had to service the things and it was a pain!
