发明名称 TOOL, SYSTEM AND METHOD FOR RAILCAR MAINTENANCE
摘要 Embodiments of a mechanical tool for railcar maintenance are disclosed, which are most suitable for handling heavy components during undercarriage operations. In one particular embodiment, the tool may include: a cantilever beam having a first end and a second end; a support element disposed between said first end and said second end for pivotally attaching said cantilever beam to a supporting device; a first attachment element configured to grip a first railcar component; a safety latch mechanism, at said first end, for securing said first attachment element, including when said first railcar component is gripped by said first attachment element, and for preventing disengagement of said first attachment element unless said cantilever beam is in a substantially level position; and a weight element adjustably disposed between said support element and said second end, wherein said weight element, when positioned at a first predetermined stop location marked along said cantilever beam, substantially counterbalances said first railcar component gripped by said first attachment element at said first end.
