The HK-PTMS-FS-0807-47-A is a full-size, trailer-mounted portable changeable message sign with a 3156 × 1563 mm amber LED display, three-line text and graphic symbol capability, solar-powered off-grid operation, engineered for highway work zones, incident management and emergency traffic control.
Share：
The HK-PTMS-FS-0807-47-A is part of the HANKUN variable message sign range, built for road authorities, contractors and rental fleets that need a legible, power-autonomous message sign at the roadside. It is a full-size trailer-mounted portable changeable message sign (PCMS), and its published figures are taken from the released engineering drawings.
PCMS
The standard industry term used by DOTs, contractors and rental fleets across the United States and Canada for this class of roadside equipment.
Trailer VMS
In Australia the trailer-mounted version of this equipment is commonly specified as a trailer-mounted VMS board, per AS 4852.2 practice.
Trailer VMS
New Zealand road authorities and contractors likewise refer to the trailer-mounted version as a trailer-mounted VMS board in tenders and specs.
— Core Characteristics
01
Every model in this range is a full-matrix display — each pixel is individually addressed — so message text, left and right arrows and work-zone warning symbols can all be combined on the same panel. Models differ in pixel matrix, display colour and active display area, not in whether symbols can be shown. Symbol capability is stated as a display capability and is not tied to any compliance claim.
02
400.0 mm (15.75 in) with the 5 × 7 character matrix; up to 457 mm (18.0 in) with the 8-pixel-row character matrix. Character height depends on the character matrix selected, so the two are always published together.
03
56 × 28 pixels, 5 LEDs per pixel (5 mm through-hole LED, single colour).
04
3156 × 1563 mm (124.25 × 61.54 in) — the illuminated area, stated separately from the cabinet.
05
3 lines × 8 characters per line (variable format) — stated together with the number of characters per line.
06
Amber. A five-colour configuration of the same platform is available; it is linked from this page.
07
Cabinet 3356 × 1763 mm on a 100 mm border basis, depth 200–250 mm. Trailer-mounted with a road-tow configuration.
08
Display brightness and grey level are adjusted to ambient light conditions; a manual brightness setting is also available. The display therefore draws less power in low light, which extends the working time available from the solar array and battery bank.
09
Powder-coated and oven-baked finish. 2,000 lb (907 kg) capacity; 5-on-4.5 in. bolt-circle idler hub. Double-eye leaf spring group, 1.5 t (3,300 lb) gross capacity. Wheel track 1,800–2,200 mm matched to the active display area. Tires ST205/75 D15. Lifting: electro-hydraulic; manual winch (optional).
10
4G; GPS position reporting. Message management from phone, tablet or PC. Open API and SDK protocol provided, for integration into an existing fleet management platform.
11
This page states what is confirmed and what is not. Confirmed for this model: the 56 × 28 display matrix, the 3156 × 1563 mm active display area, the character height of 400 mm (15.75 in) and the pixel structure, together with the solar array, battery, chassis and lifting figures. The remaining items are listed as to be confirmed rather than estimated, so nothing on this page is a placeholder value.
12
Every published dimension — including the 56 × 28 matrix and the 3156 × 1563 mm (124.25 × 61.54 in) active display area — is taken from the released engineering drawings and is internally re-checkable, so the figures can be quoted in a project specification.
Continuous multi-week deployment on mainline approaches. This model carries 3 lines of 8 characters on a 56 × 28 matrix — 3156 × 1563 mm (124.25 × 61.54 in) of active display area at a 400 mm (15.75 in) character height — and the single amber output
Staged closures and narrow work areas. A 3356 × 1763 mm cabinet suits shoulder and bridge-deck placement, the 56 × 28 matrix holds the staged sequence, and a single-colour message means the closure line does not have to be abbreviated.
Diversion messages that need several lines at once. 3 lines × 8 characters per line (variable format) lets the closure, the speed and the direction stand together, and one message colour covers a diversion that runs over several days.
Fast deployment where a clear message matters more than message volume. Road-tow trailer mounting with an independent solar array puts the sign in position from one movement, the 56 × 28 matrix lets the warning be reshaped as the incident develops
Staged traffic management over several days. 3156 × 1563 mm of display area is what a venue approach is read against, and the amber output, which needs no colour decision from the operator, lets the operator separate the instruction that matters from the supporting lines.
Long-term or semi-permanent mounting at a fixed point. The 56 × 28 matrix and the 3356 × 1763 mm cabinet can be specified against the viewing position, and single-colour text on a full-matrix panel carries routine notices without a redesign.
§ MUTCD Part 6 (Chapter 6F)
§ MUTCD Table 2E-4
US practice sets letter height from the posted approach speed. MUTCD Part 6 (Chapter 6F) gives 18 in (457 mm) as the minimum letter height for a portable changeable message sign and permits shorter letters on low-speed facilities; Table 2E-4 adds that 450 mm (18 in) should be used where speeds are greater than 90 km/h (55 mph), in persistently poor weather, or where the driving task is complex. Messages are limited to two phases, and animation, flashing and scrolling are not used.
This model reaches 457 mm characters, which is the 18 in class the US guidance names for approaches above 55 mph (90 km/h), carried as 3 lines of 8 characters in the single amber output.
§ AS 1742.3:2019
§ State roadworks guidance
AS 1742.3:2019 and the state roadworks guidance size characters to the approach speed, at roughly 120 mm for 60 km/h approaches and 160–200 mm for 80 km/h approaches, with the larger alphabet series applied to high-speed and multi-lane works. The sign face is confirmed with the road authority for each project.
This model’s 457 mm characters are at or above the 160–200 mm band used for 80 km/h approaches, and the single amber output carries 3 lines of 8 characters on the 56 × 28 matrix.
§ NZTA CoP for Temporary Traffic Management
§ Published NZ figures for LED message signs
The NZTA Code of Practice for Temporary Traffic Management sets a temporary speed limit at least 20 km/h below the normal limit, gated across the carriageway, with repeat signs at 400 m intervals. The published NZ figures for LED message signs set characters at not smaller than 300 mm inside a 50 km/h area and not smaller than 400 mm elsewhere.
This model’s 457 mm characters are at or above the 400 mm figure used for LED message signs outside 50 km/h areas, with a 56 × 28 matrix in the single amber output carrying 3 lines of 8 characters.
§ Traffic Signs Manual Ch. 8, Table A1.2
§ TSRGD 2016
The UK sizes characters by x-height rather than cap height. Traffic Signs Manual Chapter 8 (Table A1.2) runs from 62.5 mm at 30 mph to 200 mm on dual carriageways at the national speed limit, and TSRGD 2016 sets the legal x-height limits at 35 mm to 400 mm, so a cap-height figure has to be converted before it can be placed in that table.
A cap height of 457 mm in the single amber output converts to about 326 mm x-height on the 1.4 cap-to-x ratio used internally for comparison only, which sits at or above the 200 mm band used on dual carriageways at the national speed limit.
§ EN 12966:2014+A1:2018
EN 12966:2014+A1:2018 classifies a variable message sign on luminance, beam width, colour and luminance ratio, with a temperature class. The class required follows the road type, the viewing geometry and the climate at the site, and it is stated per configuration rather than as a single figure.
At motorway viewing geometry the beam width and luminance class carry most of the weight, because the sign is read from the far end of a long approach. For this 56 × 28 amber configuration the specification is stated as designed to meet the clauses relevant to the destination market, with CE marking and Declaration of Conformity documentation available and testing available on request.
The 56 × 28 matrix and 400 mm (15.75 in) characters are the two figures an agency can put against the posted approach speed, and the compliance path for the market is stated on this page rather than left for the tender.
3 lines of 8 characters at 400 mm (15.75 in) keeps one message phase readable while the closure moves, and the 3156 × 1563 mm display area is the figure used to place it against the advance warning arrangement. The same platform is also published in five-colour if a second scheme needs a priority colour line.
One 3356 × 1763 mm cabinet and one controller across the fleet means one spare-part set and one training path, and the 56 × 28 matrix is the figure to quote when a client asks what the unit can display.
Lane status, speed and diversion messages on a 56 × 28 display, with the remote arrangement described as an open API and SDK so the sign can be tied into an existing traffic management platform.
One matrix · two layouts
56 × 28 matrix→3 lines × 8→
400 mm⇄regrouped rows→457 mm
Character height and line count are the same decision, and this platform answers it with its matrix rather than with a menu: a 56 × 28 grid laid out for 3 lines of 8 characters, giving 400 mm (15.75 in). The same rows can also be grouped into a taller character, which is how this model reaches 457 mm. The trade is height against the number of lines
Pixel → stroke → character
5 LEDs / pixel→5 mm through-hole
→clean strokes→400 mm character
The pixel structure is published as: 5 LEDs per pixel (5 mm through-hole LED, single colour). That is what lets a 400 mm (15.75 in) character be assembled from a character matrix rather than drawn as a single line of block letters, because the pixels are large enough to build a character without crowding the strokes at this height.
Power on board · site off the brief
Solar + battery→no generator / cabling→
towable 3356 × 1763 mm
The platform carries its own power, which takes the site out of the design brief: no generator, no cabling and no mains connection has to be arranged before the sign can work. What is left to design is a 3356 × 1763 mm cabinet that tows between long-duration sites behind vehicles the customer already runs

We reply with the configuration that matches your market, duty and message set — amber on this platform, or the five-colour model if Q4 says so.
Colour branch
Identical display geometry, only the colour configuration changes.
This is a colour choice, not a selection branch: it does not change resolution, character size or message format.
Size branch
Taller matrix: up to 513 mm (20.2 in) characters, or four lines.
Choose the extended model when the road speed or the message structure requires it.
Mounting branch
The same display class in the other mounting configuration.
Trailer-mounted suits long-duration deployment and towing; truck-mounted suits vehicle-integrated operation.
If the viewing distance or the message volume is beyond what a 3156 × 1563 mm active display area can serve, the HK-PTMS-FS-0807-48-A is the next step up in the amber trailer-mounted range, with a 56 × 32 matrix and a 3163 × 1788 mm active display area.
If the sign can be placed closer to the traffic, the HK-PTMS-MS-0809-37-A covers the same message format at a smaller footprint, with a 56 × 27 matrix and a 2619.1 × 1321 mm active display area.
→Confirmed per project
The other mounting platform is confirmed per project, because no directly equivalent model is published in this size class.

The HK-PTMS-FS-0807-47-A is one of 19 catalogued models — 15 of them published and available for specification — and it is the 13th by active display area among the published models. Within the full-size amber trailer group it is the 6th of 7. It carries a 56 × 28 pixel matrix — 56 pixels across and 28 down — over 3156 × 1563 mm (124.25 × 61.54 in) of active display area, with a character height of 400 mm (15.75 in) extending to 457 mm (18.0 in) with the 8-pixel-row character matrix.
Those five figures are the whole basis on which this model is chosen: the rest of the range differs in matrix, colour and display area, not in what a full-matrix display can do.

— Procurement Case
01
A 56 × 28 display over 3156 × 1563 mm of active display area deploys on a road-tow trailer with its own power, so the site needs no generator and no cabling for the duration of the works.
02
The five published figures — 3156 × 1563 mm active display area, 400 mm (15.75 in) character height, 56 × 28 matrix, amber display colour and a 3356 × 1763 mm cabinet — can be quoted straight into a project specification, because each one is traceable to the engineering record.
03
The amber output carries one message layer on this 56 × 28 display, so a crew is briefed once and there is no colour decision to make in service — and the same-platform options mean one spare-part set and one training path across a mixed fleet.
04
At 3156 × 1563 mm this model is the 13th largest active display area among the 15 published models, and the 6th of 7 in the full-size amber trailer group — so it can be placed against the other models on published figures rather than on a sales description.
