The Trewhella monkey jack, invented to help land clearance in Australia during the 1880s by the Trewhella brothers was designed primarily for timber moving and as an aid for stump removal.
Two jacks were made, model C.D. 5 ton and model C.E. 10 ton, the larger jack having two spears or pointed extension bars, the longer spear for larger tree work, the small spear for general work and small trees. Model C.D. had one spear.
Both models had two lifting claws at different heights, the lower claw being useful for roots etc. The top claw was intended for going under loads the lower claw had raised to its limit. The bottom claw was especially useful for rolling timber.
Prices in 1929 were, 10 ton model, jack complete £13.10s and the 5 ton model, jack complete £ 8.15s. Catalogue address was Island Rd, Handsworth, Birmingham. See also the Trewhella monkey winch
