  • a material handling vehicle for use in an underground mine, comprising a mobile body, a boom assembly extending from said mobile body, said boom assembly having a first end portion adjacent said mobile body and a second end portion spaced from said first end portion and extending from said mobile body, a pivot pin secured to said mobile body and extending upwardly therefrom, said boom assembly first end portion being pivotally connected to said upwardly extending pivot pin to allow a lateral swinging movement of said boom assembly relative to said mobile body, a first actuating means mounted on said mobile body and connected to said pivot pin for pivoting said boom assembly laterally relative to said mobile body, first connecting means for securing said boom assembly first end portion to said mobile body, said first connecting means including a horizontal pivot pin forming a horizontal axis to effect upward and downward movement of said boom assembly relative to said mobile body and to pivotally connect said boom assembly first end portion to said vertical pivot pin, second actuating means being connected at one end to said upwardly extending pivot pin and connected at the other end to said boom assembly first
  • the boom assembly first end portion is preferably formed by an elongated channel-shaped member that is pivotally secured by the connecting apparatus to the pivot arrangement.
  • the channel-shaped member is pivotal through a vertical plane about a horizontal axis formed by the pivot arrangement.
  • the boom channel-shaped first end portion has an open end opposite the end that is pivotally connected to the pivot arrangement.
  • the boom assembly second end portion extends through this open end in a manner to permit slidable movement of the boom assembly second end portion relative to the boom assembly first end portion.
  • the boom assembly second end portion preferably also has an elongated channel-shaped configuration similar to the boom assembly first end portion.
  • the cross-sectional area of the boom assembly first end portion is greater than that of the boom assembly second end portion to permit extension and retraction of the second end portion relative to the first end portion.
  • a piston and cylinder assembly is disposed within the boom assembly second end portion and is secured at its end portions to the respective portions of the boom assembly. With this arrangement actuation of the piston and cylinder assembly is operable to move the boom assembly second end portion in a telescoping manner relative to the boom assembly first end portion and thereby change the effective length of the boom member.
  • the material engaging device is securely engaged to the outer end portion of the boom assembly second end portion.
