Abstract

Transverse frame members (14, 16) extend across and are connected to longitudinal frame members (10, 12). Frame member (14) divides longitudinal frame members (10, 12) into major and minor parts (20, 22, 24, 26). The minor parts (24, 26) are braced by gussets (70, 72) which extend between the minor parts (24, 26) and a vertical web portion (68) of the transverse beam (14). The minor parts (24, 26) of the frame members (10, 12) and the central portion of the frame member (14) form a nook (76) in the cylinder components (80, 82, 84, 102, 104) are received. Piston rod portions (92, 94, 96) of the assembly of linear motors extend from the cylinder component portions to guide bearings (100) mounted in openings (56, 58, 60) formed in the vertical web (54) of the second transverse beam (16). Bolts are used to connect the inner corner portions of the assembly of linear hydraulic motors to mounting pads (34, 36). More bolts are used to connect the outer corner portion of the cylinder components to mounting lugs (38, 40).

Dependent claims

A mounting frame for an assembly of linear hydraulic motors, each having a cylinder component and a piston component, said cylinder component having a closed first end and an opposite second end, said piston component including a piston rod projecting out from the second end of its cylinder component, and said mounting frame comprising:

a pair of longitudinal frame members laterally outwardly bounding the linear hydraulic motors;
a transverse frame member extending perpendicular to the longitudinal frame members and dividing them into major and minor parts;
said transverse frame member being connected to the longitudinal frame members, with the minor parts of the longitudinal frame members extending in one direction from the transverse frame member and the major parts of the longitudinal frame members extend in the opposite direction from the transverse frame member;
said transverse frame member having a vertical portion that includes a downwardly opening recess in its extent between the longitudinal frame members;
said vertical portion of the transverse frame member having mounting pads for the second ends of said cylinder components at the ends of the recess, where the minor parts of the longitudinal frame members meet the transverse frame member;
said minor parts of the longitudinal frame members having outer ends and mounting lugs at the outer ends for the outer ends of the cylinder components;
wherein the mounting frame is adapted to receive the cylinder components of the plurality of linear hydraulic motors laterally between the minor parts of the longitudinal frame members and longitudinally between the mounting pads on the transverse frame member and the mounting lugs at the outer ends of the minor parts of the longitudinal frame members;
wherein the mounting pads are adapted to be connected to the second ends of the cylinder components;
and
wherein the mounting lugs are adapted to be connected to the first ends of the cylinder components.
