How, by Utilizing a Few Scrap Components, a Really Serviceable Engine Hoist was Constructed
THOSE operators who are in need of an engine crane and who have by them. the necessary material and, scrap components, may find that one, as here described, and which has been made. by a reader, will meet their needs, The base member is an 8-ft.. length of 3-in. by 4-in; H-section girder. ThiS is cut 'away at one end to. take .the banjo housing of an old Morris 11.9 h.p. axle, which is welded in position.
. To the top end of the tbrque tube' is welded a short length of channel iron, to which is pivoted the lifting arni. The latter is a 5-ft. 4-in, length. of 3-in. diameter steel tubing, to which a piede of channel ironis • welded at a
• point 1 ft, 10 ins, from one end, as shown.
Brake drams provide tivo points of support, with a suitablewheel arranged at the end of the base niernber forming the third, If necessary,thie. third wheel could he arranged to give a castor action, and should be small enough to go under the front axle of a vehi.cle.
For operating the crane either screw tackle or blocks can be used. We understand that a crane made substantially. as described is giving entire satisfaction, but the: builder suggests that, before using for engine removal, it should be tested with a load almost double that whidh it will be called upon to lift in the ordinary way.
The drum indicated is 10 ins long and 3i ins. diameter. We are informed by the builder that, with a pair of rope blocks, one man can quite easily remove Or replace an engine, and that the appliance is quite stable under load.
In view of the nature 'of the loads which such a hoist is called upon to carry,. It , is imperative that care be exercised in making perfect welded joints. No liberties should be taken in respect of the dimensions of the main components, it being wiser to err on the heavy side.
