Forklift Impact Monitor
IM3-Defender Series
Reduce Damage Costs

Defender IM3  –  Managing Forklift Impacts in Real Time

Forklift On-board Impact Detection with RFID Card Reader for Authorized Operator Access Control and Real Time Reporting.

The Defender IM3 Impact Monitor provides lift trucks fleets of all sizes and location with a realistic approach to reducing damage costs and improving operator safety in ‘real time’ for as it happens response. 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.

IM3 Defender Forklift Impact Monitor

The system is engineered to provide information not ‘interruption’ and links operator usage to recorded impacts in ‘real time’. The IM3 is designed to provide wireless RF notifications of events as they happen and deliver them through emails that can be accessed on PDA devices, keeping management connected and informed regardless of location or proximity to equipment. In addition the IM3 provides reporting options that include event select automatic sends, daily, weekly or monthly. Also unique to the Defender IM3 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

• Rugged, Reliable, Accurate

The system is easily installed in 1 to 1.5 hours and connects to any lift truck. Once installed, a simple setup process includes programming operator IDs and setting the accelerometer to acknowledge the damage threshold of a specific application. The system is designed to be fully supportable by the end user to allow for complete versatility in any application fast and with little effort.

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.
