Shovel including a display device
First Claim
1. A shovel, comprising:
- a cabin in which a display monitor is provided;
an upper-part turnable body that includes the cabin;
an electric turning mechanism that causes the upper-part turnable body to turn;
a turning electric motor that drives the electric turning mechanism;
an inverter that controls an operation of the turning electric motor;
a current sensor provided in the inverter, the current sensor detecting a state of driving of the electric turning mechanism;
a processor; and
a memory storing a program that, when executed by the processor, causes the shovel tocalculate electric power pertaining to an operation of the turning electric motor based on a detection value of the current sensor, the electric power varying in accordance with an operation of turning the upper-part turnable body that is being performed by an operator of the shovel,generate turning operation display data for graphically representing the calculated electric power, andcause the display monitor to graphically display the generated turning operation display data on a multilevel scale.

Abstract
A shovel includes a cabin in which a display monitor is provided, an upper-part turnable body that includes the cabin, an electric turning mechanism that causes the upper-part turnable body to turn, a turning electric motor that drives the electric turning mechanism, a detector that detects the state of driving of the electric turning mechanism, and a display control part configured to generate information to be displayed on the display monitor and cause the display monitor to display the generated information. The display control part is configured to calculate a physical quantity pertaining to an operation of the turning electric motor based on a detection value of the detector, generate turning operation display data for graphically representing the calculated physical quantity, and cause the display monitor to graphically display the generated turning operation display data.
