A vehicle, such as an extendible boom forklift, that includes a personnel work platform (PWP). The personnel work platform includes a shut-off switch that is connected to the electronic controls for the extendible boom forklift. The operational controls of the extendible boom forklift include a personnel work platform control system that modifies the operation of the extendible boom forklift when the forklift is in a PWP mode. The PWP control system receives inputs from the shut-off switch, a PWP system actuation switch, a service brake pressure switch and a level sensor/switch such that the control system enables the PWP mode only upon satisfying certain safety-related concerns. In the PWP mode, the control system engages the parking brake, declutches the transmission, locks the frame stabilizing cylinder, deactivates the auxiliary and tilt hydraulic functions and limits the frame leveling rate to slow speeds.

The spin cast die assembly of claim 2, wherein: the flyweight engagement surface is frustoconical and faces generally radially inwardly. 5. The spin cast die assembly of claim 2, wherein: the mounting member has an inner end for abutting against the casing, and the flyweight engagement surface faces generally radially outwardly and axially towards said inner end. 6. The spin cast die assembly of claim 1, wherein: each flyweight member includes a tool engaging portion for engaging a tool, each flyweight member cooperating with said tool to pivot out of engagement with the mounting member as the tool is moved with respect to the mounting member. 7. The spin cast die assembly of claim 6, wherein: each flyweight member includes an axially outer arm and an axially inner arm, the outer arm being engageable with the tool. 8. The spin cast die assembly of claim 1, wherein: each flyweight member includes a tool engaging portion for engaging a tool, each flyweight member cooperating with said tool to pivot out of engagement with the mounting member as the tool is rotated with respect to the mounting member. 9. The spin cast die assembly of claim 1, wherein: each flyweight member includes a tool engaging portion for engaging a tool, the tool comprising a cylindrical body having a plurality of tabs projecting outwardly therefrom, the tabs engaging the flyweight members and pivoting the flyweight members out of engagement with the mounting member upon rotation of the tool, so that the flyweight support member and the flyweight members can be axially withdrawn from or inserted into the assembly. 10. The end cap assembly of claim 1, wherein: a flyweight support member is received by the mounting member, and the flyweight members are pivotally coupled to the flyweight support member. 11. An end cap assembly for retaining an insert within a casing of a spin cast die assembly which rotates about a rotation axis, the end cap assembly having a mounting member for attaching to an end of the casing and a plurality of flyweight members which pivot when the assembly is spun and hold the insert within the casing, characterized by: a flyweight support member received by the mounting member, the flyweight members being pivotally supported on the flyweight support member, and the flyweight members being located radially internally with respect to the mounting member and being engagable with an internal surface of the mounting member, flyweight members urging the flyweight support member and the insert axially inwardly in a direction parallel to said rotation axis when the assembly is spun. 12. The end cap assembly of claim 11, wherein: a portion of the mounting member forms a flyweight engagement surface; and each flyweight having a mounting member engagement surface formed on an arm thereof for operatively engaging the flyweight engagement surface. 13. The end cap assembly of claim 11, wherein: the flyweight engagement surface extends from an outer edge radially inwardly and axially away from the shoulder to an inner edge. 14. The end cap assembly of claim 11, wherein: the flyweight engagement surface faces generally radially inwardly and towards the shoulder. 15. The end cap assembly of claim 11, wherein: each flyweight member includes a tool engaging portion for engaging a tool, and cooperating with said tool to pivot out of engagement with the mounting ring as the tool is moved with respect to the insert. 16. The spin cast die assembly of claim 11, wherein: each flyweight member includes a tool engaging portion for engaging a tool, each flyweight member cooperating with said tool to pivot out of engagement with the mounting member as the tool is rotated with respect to the mounting member. d a lid housing pivotally connected to the base housing. Operating heat from the microprocessor is transferred to the lid housing, for dissipation therefrom, via a specially designed thermosyphoning heat pipe structure formed from first and second heat pipes. The first heat pipe representatively has a rectangular cross-section, an evaporating portion thermally communicated with the microprocessor, and a coiled condensing portion centered about the lid hinge line and having a circularly cross-sectioned interior side surface portion defined by flat sides of the first heat pipe. The second heat pipe has a circular cross-section, an evaporating portion pivotally received within the coiled first heat pipe portion, and a condensing portion thermally communicated with the lid housing. When the lid housing is opened and closed, the evaporating portion of the second heat pipe is rotated within the coiled first heat pipe portion and slidably engages its circularly cross-sectioned interior side portion.
