  • Patent number: 6655486
    Abstract: An engine enclosure for a construction vehicle which is simply constructed and small-sized, while improving the cooling efficiency and lowering the noise. The engine enclosure including: an engine hood 15 having an ambient air inlet port 24; and engine side covers 16 having ambient air inlet ports 38. The engine enclosure is constructed to include an ambient air screening wall around a muffler 5 so that the cooling ambient air taken from the ambient air inlet ports 24 and 38 may flow to a fan without contacting with the muffler 5. With this construction, the air around the muffler and especially at a high temperature in the engine room and the cooling ambient air taken from the engine hood and the engine side covers can be screened from each other so that the temperature rise in the cooling ambient air to be fed to a heat exchanger such as a radiator can be reduced to improve the cooling efficiency.

  • Patent number: 4099449
    Abstract: An electromagnetic bucket positioner having an electromagnet disposed to selectively latch, when energized, a directional control valve of a bucket positioning system. The electromagnet is arranged in such a manner that only when a manually operable control lever is shifted to a rack-back position, the electromagnet serves to latch the control lever in the rack-back position. A normally-closed electric switch is provided and is adapted to be opened upon selected movement of the piston rod of a hydraluic cylinder associated therewith, so as to interrupt electric current flow to the electromagnet, de-energize the same and release the control lever. A loose spring device is provided in the system to facilitate movement of the control lever from the rack-back position if and when desired.
