Tower crane 3-in-1 visual safety system

▌ 01 PRODUCT OVERVIEW · ZNAQ-DG2

Tower crane 3-in-1 visual safety system

One kit covers three jobs: hook vision, multi-crane anti-collision and driver identity.

A single 11.6-inch screen in the cabin shows the live hook picture and the working data — height, amplitude, slewing, load, inclination and wind speed. Every sensor is fitted to the structure the crane already has, with no structural change, and one host in the cabin does the calculation and the communication for the whole crane.

The system is modular by function: hook vision only, hook vision plus multi-crane anti-collision, or the same hardware with face recognition added — the difference is configuration, not equipment.

KEY POINTS

● Modular by function — one kit per tower crane

● Height and amplitude range 0–300 m

● 1080P hook picture to the cabin screen and the site office

● Several anti-collision modes run at the same time

● Face recognition is optional

▌ 02 SYSTEM COMPOSITION · STANDARD CONFIGURATION

What goes on the crane

The standard configuration is one unbroken chain from sensor to cloud.

▌ SENSORS Two absolute encoders read height and amplitude; a Beidou rotation and tilt module covers slewing and inclination; load goes through real nylon wheels on a thickened bracket; wind speed uses ABS cups.

▌ VISION & HOST The lens tracking kit rides the trolley with the hook, and the host in the cabin collects every camera, sensor and alarm, does the calculation and drives both the cabin display and the 4G link.

▌ POWER The battery mechanism, battery management module, contact charging mechanism, charging pad and charge lamp keep the kit powered — the crane picks up power as soon as it slews.

Every number on the drawing matches one mounting position in the assembly view: sensors and vision first, then host, cabin display and lens tracking kit, then the power and charging parts.

KEY DATA

▌ HEIGHT / AMPLITUDE absolute encoder 0–300 m, 0.1 m, IP65

▌ SLEWING / INCLINATION Beidou module 360° / 1°, 0–15° / 0.01°

▌ LOAD 0–10 t ±5% accuracy, 0.01 t resolution

▌ WIND SPEED 0–60 m/s start-up 0.2 m/s

▌ HOST 4G link drives the cabin display and the cloud platform

▌ THREE STEPS mount the sensors → one host → screen, cloud, site

▌ 03 CORE HARDWARE

One host, one screen, one camera, five sensors

Every unit comes from our own production.

▌ THE HOST The centre of the system: cameras, sensors and alarms all report to it, and it does the calculation and the 4G communication.

▌ THE CABIN DISPLAY An 11.6-inch, 1920×1080 tempered glass panel running on AC 220 V at no more than 20 W, expandable to four screens in a long cabin.

▌ THE LENS TRACKING KIT A trolley-mounted bullet camera with a 2 MP, 23× optical zoom, IP65 and DC 12 V — it moves with the trolley and the hook, so there is no blind zone.

Five sensors turn every movement of the crane into a readable figure: height, amplitude, slewing and inclination, load, and wind speed. All of them are IP65 and maintenance-free once fitted.

KEY DATA

▌ MAX HEIGHT 0–300 m 0.1 m resolution

▌ MAX AMPLITUDE 0–300 m 0.1 m resolution

▌ SLEWING / INCLINATION 360° / 1° 0–15° / 0.01°

▌ RATED LOAD 0–10 t ±5%, 0.01 t resolution

▌ WIND SPEED 0–60 m/s start-up 0.2 m/s

▌ HOOK PICTURE 1080P 2 MP · 23× zoom

▌ POWER SUPPLY AC 220 V / 50 Hz ≤ 20 W in total

▌ 04 CORE FUNCTIONS

See the hook, keep the cranes apart, know who is driving

▌ HOOK VISION The first line of defence on every tower crane: the camera rides the trolley and puts the hook and the landing area straight into the cabin, so the operator is never lifting blind.

▌ MULTI-CRANE ANTI-COLLISION Sets slow-down, warning and stop zones per crane; each tower sends its own angle and position to its neighbours over 4G, so an alarm comes before two jibs can reach into each other’s working area.

▌ FACE RECOGNITION · OPTIONAL If the face on the seat does not match a registered identity, the equipment will not release control — cards can be handed over and keys shared, but a face cannot, and every unlock is tied to a named driver.

The right-hand side of the page is the screen the operator watches: height 42.6 m, amplitude 28.4 m, slewing 137°, load 3.20 t, moment 136 t·m, inclination 0.42°, wind 5.4 m/s — plus the 1080P hook picture. Every figure refreshes with the picture, so the crew can judge the working condition at a glance.

KEY POINTS

● Hook vision and anti-collision are standard; face recognition is optional

● Slow-down, warning and stop zones configured per crane, per site

● Unlocks are tied to a named driver and can be traced

● The same stream reaches the site office and the cloud over 4G

▌ 05 THE SITE · LIVE PROJECTS

What the site actually sees

One system on a real site, seen four ways.

▌ ON THE PLAN The slewing envelope of every crane is drawn together with the site obstacles, so the overlapping working zones between neighbouring towers are obvious.

▌ CLOUD PLATFORM Puts every crane, every reading and every alarm on one dashboard, at the site office or on a phone.

▌ IN THE CABIN A tower crane in Bontang, Indonesia — the live hook picture and the working data on the same screen.

▌ THE TOWER GROUP Where the kit earns its keep: the cranes exchange position and angle over 4G, and the system knows which jib will enter whose zone before the operators do.

Software language, logo and hardware configuration can be customized for your market. Tell us the site, the crane model and how many towers — we will configure the kit and quote it.

KEY POINTS

● Plan / cloud platform / cabin / tower group — four site views

● Software language and logo customizable

● Hardware configuration built per project, sensor to cloud as standard

● Several anti-collision modes run at the same time, not one or the other
