Forklift Impact Detection
Reduce Forklift Damage

IM-2 Defender SeriesForklift Impact Detection

The Defender IM2 Impact Monitor provides small to medium lift truck fleets with a realistic approach to reducing damage costs and improving operator safety. Designed for easy integration and lasting success the system utilizes industry leading 16 G notification on the accelerometer with units of 0.5 to properly capture the weight per unit mass sensitivity of all applications. The system is engineered to provide information not ‘interruption’ and links operator usage to recorded impacts in real time.  System will provide management and safety stakeholders the ability to access that data when needed to investigate or promote safe driving. Also unique to the Defender IM series is the two-tier safety notification design that allows for companies to give warning thresholds to drivers in advance, providing a tool to eliminate damage or un-safe situations before they happen.

Forklift Impact Monitor - Defender IM-2

The RFID operator access HID card reader is integrated into digital indicator housing with IVDT Inc. proprietary software that allows self programming, deleting and management of authorized vehicles operators on IM3 SkidWeigh / Defender equipped with ProxPoint Plus RFID proximity card readers. There is no need for any additional programming devices.  When power is applied to the system HID reader LED will flash green 3 times while the beeper beeps simultaneously.
