VLG-4 (M30/K4) Engineered Crash-Rated Vertical Lift Gate & TYM-VSA Operator System
Product Notes
- Closes single clear opening widths up to 50 feet.
- Standard gate panel heights up to 10 feet (contact manufacturer regarding taller applications).
- Standard clear opening heights up to 15 feet (contact manufacturer regarding taller applications).
- *Engineered to meet ASTM F2656-07-M30-P1 for cleat opening widths up to 26’; ASTM F2656-07-M30-P2 for clear opening widths up to 50’.
Product Summary
The VLG-4 Engineered Crash-Rated Vertical Lift Gate incorporates all the functional features of the non-rated Vertical Lift Gate plus bi-directional crash impact protection (can withstand crash impact from either side of the opening). By virtue of design, the VLG-4 is fast and provides a high level of security. While capable of spanning larger clear opening widths up to 50’, a minimum amount of space is needed to each side of the clear opening.

Frequently Asked Questions
TYMETAL has been in the perimeter security solutions market since 1985. With more than three decades of experience designing, manufacturing and installing crash rated barriers, we have encountered many questions along the way. A few of the more common questions below. If you don’t find the answers you’re looking for, feel free to contact us at 888-978-4283 or online.
What crash rating defines the VLG-4 *Engineered Crash-Rated Vertical Lift Gate’s performance?
The VLG-4 Vertical Lift Gate is *Engineered to perform to ASTM F2656-07-M30-P1 for clear opening widths up to 26’ and to ASTM F2656-07-M30-P2 for clear opening widths up to 50’. See below:
- P1: Will stop a 15,000 lb. vehicle traveling @ 30 mph within 1 meter upon impact.
- P2: Will stop a 15,000 lb. vehicle traveling @ 30 mph within 1 to 7 meters upon impact.
* Engineered: The gate or barrier is designed to pass the crash test stated based on extrapolating previous test results, engineering calculations and/or modeling. It may not have undergone an actual test. A stamped certification (PE stamp) can be provided to ensure compliance.
How does a vertical lift gate conserve space compared to swing or slide gates?
The vertical lift gate rises straight up, requiring a minimum amount of space to each side of the clear opening width, and no back-clearance. It is highly efficient for space-constrained locations such as narrow access corridors, multi-lane checkpoints flanked by barriers, and building-integrated entries where swing or slide gate geometries are not feasible.
What operator system powers the lift system?
The VLG-4 vertical lift gate system is powered by TYMETAL’S TYM-VSA variable speed operator, which is integrated into the gate system’s unique design. It includes a soft start/stop feature; maximum gate speed is 1.5 feet per second. It’s particularly fast for larger openings, as it only needs to travel 15 feet (typical clear opening height) up or down. For example, a VLG-4 gate system having a clear opening width of 50 feet can open or close in approximately 10 seconds. In the event of a power outage a crank handle located in the motor box can open and close the gate panel.
Are there safety sensors or redundancy systems for obstruction detection?
The VLG-4 vertical lift gate system meets ASTM F2200 standards (Standard Specification for Automated Vehicular Gate Construction) and is UL 325, Classes III and IV compliant. The TYM-VSA operator incorporates inherent sensing and is compatible with loop detectors, photo eyes, reversing edges and presence sensors that detect obstructions in the gates travel path. A combination of sensor and detection devices can result in redundancy which, depending on the application, is often a deliberate choice.
What routine inspection or lubrication schedule maintains the systems reliability?
Refer to the Installation and Operations and Maintenance Manual. Depending on daily usage, Scheduled Maintenance is recommended at intervals between 1 and 6 months. See below:
| Cycles per Day | Scheduled Maintenance |
|---|---|
| Less than 25 | Every 6 months |
| 26 to 50 | Every 3 months |
| 51 to 100 | Once per month |
| More than 100 | Once per week |
