Jointech - JT802

The Jointech JT802 is an intelligent tank truck valve slave lock engineered for safe, low-power control of multi-valve tanker installations. Designed to operate alongside Jointech master locks (such as the JT701D and JT701L), the JT802 adds secure, remotely managed valve control and event reporting to Green-Gps compatible fleets and telemetry stacks. Its intrinsic safety certification and compatibility with intrinsically safe handheld terminals make it suitable for hazardous environments like fuel and oil transportation.

As a Green-Gps compatible device, the JT802 complements GPS tracker solutions and real-time tracking platforms by delivering valve lock status, alarm events, and route playback data that integrate with fleet management, anti-theft workflows, and fuel monitoring processes. It supports both remote online unlocking through the master lock and Bluetooth-based offline unlocking for field crews, giving tanker operators flexible, auditable access control for everyday operations and emergency response.

Key Highlights

• Green-Gps compatible slave valve lock that works with Jointech master locks (JT701D / JT701L) to scale multi-valve tank truck deployments.
• Remote online unlocking plus on-site Bluetooth offline unlocking for flexible access control across field and central operations.
• Low-power, long-term operation powered by a disposable lithium manganese battery for reliable service life in remote fleets.
• Intrinsic safety (explosion-proof) certification and compatibility with intrinsically safe handheld terminals for safe use in hazardous fuel and oil environments.
• Real-time monitoring and historical route playback on supported platforms for faster incident response and clear audit trails.
• Remote configuration of product parameters to simplify fleet rollouts and reduce field service visits.
• Combines master lock data and mobile phone positioning to provide precise asset timing and location context without assuming an onboard GNSS unit.

How It Works with Green-Gps

The JT802 integrates into Green-Gps-compatible workflows by reporting valve status, alarms, and timing data collected in cooperation with a Jointech master lock and handheld devices. When paired with a Green-Gps-enabled fleet, the JT802’s events and status updates are surfaced alongside GPS tracker position data and other telemetry to create a unified operational view.

• Real-time location and telemetry updates: Valve events and timing are linked with master lock and mobile phone positioning for situational awareness on Green-Gps dashboards.
• Remote online unlocking: Central operators can unlock valves remotely via the master lock pathway when permitted.
• Bluetooth offline unlocking: Field crews can perform on-site unlocking using a Bluetooth-capable intrinsically safe handheld terminal even when network connectivity is unavailable.
• Alarm and status reporting: Valve lock status and alarm events are transmitted to allow timely response and automated notifications in Green-Gps.
• Simultaneous control: Cloud platform and handheld terminal can both manage the JT802, enabling coordinated workflows and audit logging.

Technical Overview

Use Cases

• Fuel distribution management — coordinate valve access, delivery timing, and audit trails across multi-stop routes when used with Green-Gps and GPS trackers.
• Anti-theft protection — detect and report unauthorized valve activity or alarm events in real time to reduce fuel loss and support rapid intervention.
• Tanker transportation monitoring — link valve events and route playback for compliance, dispatching, and incident investigation.
• Secure oil logistics operations — deploy in hazardous environments with intrinsic safety certification and interoperable handheld control for safe field workflows.

Why Choose This Tracker with Green-Gps

Although the JT802 is a valve lock rather than a standalone GPS tracker, it is built to integrate tightly with Green-Gps-compatible fleets and telemetry systems. By pairing valve status and alarm events with GPS tracker location feeds and fleet management data, JT802 extends real-time tracking and telemetry into the access-control layer of tanker operations. This combined visibility helps operators reduce risk, streamline fuel monitoring and anti-theft processes, and maintain regulatory and safety compliance.

The JT802’s low-power design and disposable lithium manganese battery reduce maintenance overheads, while remote configuration and simultaneous cloud/handheld control speed deployments and lower total cost of ownership. Intrinsic safety certification and Bluetooth offline unlocking via safe handheld terminals ensure the device can be deployed across high-risk routes and facilities with confidence. For tanker operators looking to enhance fleet management, telemetry, and security workflows on Green-Gps, the JT802 is a practical, interoperable component that complements GPS trackers, ignition/immobilizer datasets, fuel monitoring systems, and Bluetooth sensors already in use.
