What is claimed is: 1. A hydraulic shovel concurrently used for crane operations comprising: an implement including a boom, an arm, a bucket and a hook for enabling crane operations, a monitor device including a monitor screen having an alarm information display portion and a parameter display port
What is claimed is: 1. A hydraulic shovel concurrently used for crane operations comprising: an implement including a boom, an arm, a bucket and a hook for enabling crane operations, a monitor device including a monitor screen having an alarm information display portion and a parameter display portion, wherein said monitor screen displays parameters related to load factors of safe-working load and alarm information during said crane operations, wherein said alarm information display portion displays a plurality of display items, the display of said plurality of display items being sequentially switchable, and wherein at least one of said alarm display portion and said parameter display portion displays an alarm color when said load factor of a safe-working load is within a dangerous area. 2. The hydraulic shovel concurrently used for crane operations as claimed in claim 1, wherein said parameter display portion is disposed in a center of said monitor screen, and wherein the alarm information display portion is disposed around the parameter display portion and is smaller than the parameter display portion. 3. The hydraulic shovel concurrently used for crane operations as claimed in claim 1, wherein an alarm sound is generated when at least one of said parameter display portion and said alarm information display portion displays the alarm color. 4. The hydraulic shovel concurrently used for crane operations of claim 1, wherein at least one of the parameter display portion and the alarm information display portion displays an advanced notice color when in an advanced notice area that is close to the dangerous area and displays said alarm color when in said dangerous area. 5. The hydraulic shovel concurrently used for crane operations of claim 4, where in at least one of the parameter display portion and the alarm information display portion generates an advanced notice sound displaying the advanced notice color and generates an alarm sound that is different from said advanced notice sound displaying the alarm color. 6. The hydraulic shovel concurrently used for crane operations of claim 1, wherein an engine condition is displayed on said monitor screen. 7. The hydraulic shovel concurrently used for crane operations of claim 6, wherein said parameter display portion is disposed in a central portion of the monitor screen, and wherein an engine condition display portion for displaying said engine condition is disposed around said parameter display portion. 8. The hydraulic shovel concurrently used for crane operations of claim 1, wherein said parameters that are displayed on the parameter display portion are related to actual load, safe-working load, operating radius, operating height and load factor of a safe-working load and others, and wherein said parameter display portion performs multiple switched display among said parameters. 9. The hydraulic shovel concurrently used for crane operations comprising: an implement including a boom, an arm, a bucket and a hook for enabling crane operations, and a monitor device including a monitor screen, said monitor screen displaying parameters related to load factors of safe-working load and engine conditions during said crane operations, wherein a Parameter display portion for displaying parameters related to said load factors of safe-working load is disposed in a central portion of the monitor screen, wherein an engine condition display portion for displaying said engine conditions is disposed around the parameter display portion, and wherein at least one of said parameter display portion and said engine condition display portion displays an alarm color when said load factor of a safe-working load is within a dangerous area. 10. The hydraulic shovel concurrently used for crane operations of claim 9, wherein the parameters that are displayed on the parameter display portion are related to actual load, safe-working load, operating radius, operating height and load factor of safe-working load and others, and wherein said parameter display portion performs multiple switched display among the parameters.
