Abstract: A puller device has a body including a pulling assembly, a support set and a brace assembly pivotally coupled above the support set. The pulling assembly includes a cylinder affixed at one acting end thereof and hooks connected onto the cylinder. The pulling assembly is secured onto a movable bracket having a bulge extended downwardly therefrom. The hooks may be driven to expandably and retractably pull mechanical components out by a hydraulic control valve assembly. The support set may expand upwardly and retract downwardly for supporting the body to vertically move. The top of the support set is axially connected with the brace assembly, so as to support the combined movable bracket and pulling assembly as a whole. A micro-adjusting means is disposed onto the brace assembly for adjusting the lateral position of the body, and another micro-adjusting means is also mounted onto the brace assembly for vertically adjusting the tilted angle of the body.

Abstract: The present invention is a multiple pump transmission jack for use with removing and repairing transmissions. The jack has two hydraulic pumps mounted on a base which are connected with interrelated oil passages or conduits formed within the base, which is operated by a pedal connected with the two pumps for drawing hydraulic oil from a reservoir and into an oil pressure cylinder to easily and quickly raise a piston rod within the oil pressure cylinder saving the operator's effort and increasing the efficiency of operation. The jack also includes an overload system that prevents the operator from placing a load on the jack which is greater than its rated load, thus preventing danger.
