Guardian Instruments has introduced a new crane safe load indicator, the Model G4. It can be configured as a single-line display or as a multi-line display, and features stainless steel buttons and bright red alphanumeric characters. It contains a “built-in-manual” which contains instructions that scroll across the display telling the operator how to use its many features. It can be mated with wired sensors and/or radio sensors.
In many cases, customers can use their existing sensors with the G4. Guardian Instruments provides wired and wireless sensors, such as load cells, wind speed, boom angle, two-block switches, cable payout, cable speed. These can be interfaced directly to the G4 without the use of dipswitches. All Guardian’s wireless/radio sensors are fully sealed, and equipped with five-year lithium batteries. Standard sensor-mounting hardware and function cut-out relay are provided at no charge.
