Since the introduction at the APWA show in August 2010, more than 1600 JackJaw sign post pullers have been put into service by cities, municipalities, and traffic sign contractors all over North America. Most of these units are examples of the JackJaw® 300 series pullers. The users love the 16 to 1 mechanical advantage (leverage) featured in these units, making easy work of pulling street signs in most parts of the country.
In some parts of the USA and Canada, heavy clay, rocky or frozen soils make it harder to pull the sign posts. In the southwest, in the states of AZ, CA, NM, and NV, kalichi clay or rock is prevalent in the soils. In GA, there is a lot of heavy red clay. In these tougher areas, the larger version, JackJaw® 500 series puller, with its 28 to 1 leverage, is becoming the tool of choice.
This mechanical advantage (leverage) means that when the operator pushes down on the handle with 100 lbs of force (easy for most operators) the JackJaw® sign post puller generates a massive upward force on the sign post of 2800 lbs!
Public works operators and contractors alike know that they can pull just about anything with the JackJaw 500 (or model 504 for square posts).
JackJaw® stake and post pullers are built in Ohio by Construction Accessories, Inc. The company currently offers 31 different models of extractors for 6 industries.
