Claims21
Loading apparatus comprising a mobile chassis, telescopic boom means mounted adjacent one end thereof to said chassis for pivotal movement about a horizontal axis, first power means for pivotally moving said boom means to thereby cause the other end of said boom means to be raised and lowered, first support means mounted on said other end of said boom means, second support means mounted on said first support means for pivotal movement about a second horizontal axis parallel to said first axis, second power means connected to said second support means for pivotally moving said second support means about said second axis, fork means, and third support means carried on said second support means mounting said fork means to said second support means for reciprocal movement relative to said second support means, whereby said fork means can be extended and retracted relative to said boom means.
Loading apparatus comprising a mobile chassis, a turntable on said chassis, a pair of upright standards on said turntable, a horizontal shaft extending between said standards to provide a first pivotal axis, a telescopic boom assembly mounted adjacent one end thereof to said shaft for pivotal movement about said axis, a boom head fixedly attached to the free or other end of said boom assembly, a carriage head pivotally mounted on said boom head, a fork carriage, and means reciprocably mounting said fork carriage to said carriage head so that said fork carriage can be extended and retracted with respect to said boom assembly.
Loading apparatus comprising a mobile chassis, telescopic boom means mounted adjacent one end thereof to said chassis for pivotal movement about a horizontal axis to thereby permit the other end of said boom means to be raised and lowered, means pivotally attached to the other end of said boom means, a reciprocal means mounted on said pivotal means, and a forklift mounted on said reciprocal means so that said forklift can be tilted into various angular positions relative to said other end of the boom means as determined by the angular position of said pivotal means and can also be extended and retracted into various positions relative to the other end of said boom means as determined by said reciprocal means.
Loading apparatus comprising a mobile chassis, telescopic boom means supported adjacent one end for pivotal movement about a generally horizontal axis, power means connected to said boom means for causing pivotal movement of said boom means about said horizontal axis to raise and lower the other end of said boom means, generally vertical support means pivotally mounted adjacent said other end of said boom means for pivotal movement about a second generally horizontal axis, power means connected to said support means for causing pivotal movement of said support means about said second axis relative to said boom means, additional support means mounted on said generally vertical support means, said additional support means projecting generally horizontally from said generally vertical support means when said generally vertical support means has been pivoted into a vertical position by said last-mentioned power means, said additional support means including a member having a free end reciprocally movable with respect to said generally vertical support means, and a forklift fixedly mounted on the free end of said reciprocally movable member.
Loading apparatus comprising a mobile chassis, a pair of standards extending in an upright direction from said chassis, a horizontal shaft extending between said standards to provide a first pivotal axis, a telescopic boom assembly mounted adjacent one end thereof to said shaft for pivotal movement about said axis, a boom head fixedly attached to the free or other end of said boom assembly, a carriage head pivotally mounted on said boom head, a fork carriage, and means reciprocably mounting said fork carriage to said carriage head so that said fork carriage can be extended and retracted with respect to said boom assembly.
