What a 360-Degree Panoramic View and an 11.6-Inch Host Change for a Truck Crane Crew

A truck crane works from wherever the site allows, and the operator often works from memory. The load, the ground crew, the stored material, the swing path of the boom and the point where the hook will land all sit outside the narrow window of the cab. A 360-degree panoramic camera and a dedicated in-cab host give the crew a single, always-on picture of the machine and the space around it, turning the routine of a mobile crane shift from looking out of a window into reading one screen.

This application note describes the CR-MON-TRUCK truck crane monitoring system, a split-modular package built for mobile truck cranes. At its centre is an 11.6-inch 1080P IPS host, 285 by 181 mm, that shows load, moment percentage, boom length, radius, height, tilt and wind alongside a 360-degree view. Around the host sit a hook-tracking camera, a 360-degree panoramic camera on the chassis, a cab face-ID camera, millimeter-wave radar for personnel and obstacle intrusion warning, and an industrial wireless bridge carrying HD video across the telescoping boom.

01  THE VIEW FROM THE CAB HAS A LIMIT

A truck crane is not a tower crane. It moves between jobs, it sets up where the access allows, and it lifts in whatever space the site can spare. On a typical steel or precast job the machine may stand with its outriggers on a road, its chassis in a lane of traffic and its boom reaching over a fence, a trench or a building line. The operator sees the load, the boom and the ground ahead, but the area behind the counterweight, the blind side of the carrier and the far end of the boom stay outside the window.

The usual answer is people. A rigger watches one side, a banksman watches another, and the operator follows voice commands. That works, and it will keep working, but it spends attention. Every blind movement becomes a conversation, and every conversation adds a pause to the cycle of the lift.

A 360-degree panoramic camera on the chassis changes the geometry of that conversation. It gives the operator a continuous view of the machine surroundings on the host display, rather than a series of spoken reports arriving from people standing in different places, each with a different angle and a different opinion about what is close and what is clear.

▌  BLIND SIDES  The counterweight side, the carrier behind the cab and the far side of the chassis are the classic blind spots on a mobile crane.

▌  ATTENTION BUDGET  Every blind movement handled by radio spends attention that the operator would otherwise give to the load and the landing point.

02  THE 11.6-INCH HOST AND WHAT IT SHOWS

The host is an 11.6-inch 1080P IPS panel measuring 285 by 181 mm. IPS matters in a cab because the operator is often looking at the screen from an angle, and because cab glazing throws reflections and glare that a poor panel cannot survive. A bright, wide-viewing screen is what makes a camera feed usable rather than decorative.

On the same screen the host shows the machine data a truck crane crew actually uses: load, moment percentage, boom length, radius, height, tilt and wind. Those are the numbers behind a capacity chart. Having them live on one display, next to the 360-degree view, means the operator does not have to look away from the picture to check where the load sits relative to the chart the lift was planned against.

The host is also where the operator switches between camera channels and plays back recorded video, using a wired mouse. A wired mouse sounds like a small detail; in practice it is the difference between a display that is only watched and a display that is actually operated. Screen switching and playback become as ordinary as using a desk computer, and the operator can move between the wide view and the hook view without leaving the seat or reaching for a menu.

▌  ONE PANEL  Load, moment percentage, boom length, radius, height, tilt and wind share the screen with the 360-degree view.

▌  IPS DISPLAY  An 11.6-inch 1080P IPS host at 285 by 181 mm stays readable from an angle and in cab glare.

▌  WIRED MOUSE  A wired mouse handles screen switching and playback, so the host is operated rather than only watched.

03  HOOK TRACKING AND THE WIDE VIEW TOGETHER

A 360-degree panoramic view and a hook-tracking camera answer two different questions. The panoramic camera answers what is around the machine: the ground crew, the stored steel, the edge of an excavation, the traffic lane behind the carrier. The hook-tracking camera answers where the hook and the load are as the boom telescopes in and out.

Put them on the same host and the operator can follow a lift from the chassis to the landing point without changing posture. The wide view sets the scene; the hook view confirms the exact position of the rigging and the load. During a blind placement the two views together remove a good deal of the guesswork that a single camera cannot resolve on its own.

This is also where the industrial wireless bridge earns its place. The camera on the hook side has to send HD video back across a boom that is extending and retracting, which is an awkward path for any cable and a hard environment for any signal. A dedicated bridge for transmit and receive keeps the picture stable as the boom moves, so the operator is not chasing a feed that drops every time the machine changes shape.

▌  WIDE THEN CLOSE  The panoramic camera frames the site while the hook-tracking camera confirms the load and the rigging.

▌  ACROSS THE BOOM  An industrial wireless bridge carries HD video along a moving telescoping boom where cabling is awkward.

04  FITTING IT TO A WORKING TRUCK CRANE

Mobile cranes are busy machines and downtime is expensive, so how a monitoring system is fitted matters as much as what it shows. The CR-MON-TRUCK package is split-modular and uses magnetic wireless sensors. That combination is deliberate: sensors attach without cutting into the machine body and without modifying its circuits.

For a fleet owner this changes the risk of the installation. There is no body cutting that invites corrosion, no splicing into looms that a manufacturer's warranty or a local inspector may object to, and no long stretch of the machine out of service while panels are opened and wiring is run. The cab power transformer gives a stable 12 volts for the host and cameras, which keeps the supply clean in a vehicle whose electrical system is anything but steady.

The hardware is IP67 and rated from minus 30 degrees Celsius to plus 70 degrees Celsius, so it is built for the range a truck crane actually meets: a cold morning on an early start and a hot afternoon on a site with no shade. The package also arrives with qualification documents for special-equipment inspection and smart-site acceptance, which are often the paperwork that decides when a machine can go back to work.

▌  NO BODY CUTTING  Magnetic wireless sensors avoid cutting the machine body, so there is no new place for corrosion to begin.

▌  NO CIRCUIT CHANGES  The fit avoids splicing into the machine circuits, so the factory wiring stays as it was built.

▌  STABLE SUPPLY  A cab power transformer gives a stable 12 volts to the host and the cameras.

05  WHAT CHANGES IN THE DAILY ROUTINE

The first change is at set-up. Instead of walking the machine to identify blind spots and posting a person at each one, the crew can confirm the surroundings on the host before the first lift. The pre-lift check gains a step in which the operator switches through the camera channels and confirms that each view is clean and live.

The second change is during the cycle. Lowering into a blind position is steadier when the operator can see the landing zone and the hook together, so the descent can be continuous rather than a series of halted commands. Radio traffic drops because less of it is needed to describe what the operator can now see directly.

The third change is after the fact. Because the host supports playback, an awkward approach can be reviewed at the end of the shift, either as a training aid or to settle a question about how a load was set. A crew that can see its own lifts tends to brief them differently the next time.

None of this replaces the lift plan, the rigging check or the exclusion zone. It changes how much of the routine is done by eye and how much by radio, and it gives the operator better information on which to exercise judgement.

▌  FASTER SET-UP  The crew confirms the blind spots of the machine on the host instead of walking around the whole machine.

▌  STEADIER CYCLES  A continuous view of the landing zone turns hesitant lowering into a steady descent.

▌  REVIEWABLE  Playback supports briefings and end-of-shift review of how a load was placed.

PROCUREMENT IMPACT

●  If a truck crane regularly works over a fence, a trench or a traffic lane, a 360-degree panoramic view targets the blind spots that hand signals cannot cover.

●  Treat the 11.6-inch host as the decision point, because it is where the panoramic view, the hook view and the live machine data meet.

●  Favour a split-modular package that avoids body cutting and circuit modification, because a cleaner fit protects the machine and the paperwork around it.

●  Confirm the 12-volt supply arrangement and the cab power transformer as part of the quotation, not as an afterthought.

●  Ask for the qualification documents for special-equipment inspection and smart-site acceptance early, because acceptance timing can decide when the machine returns to work.

●  Weigh the IP67 rating and the minus 30 to plus 70 degrees Celsius range against the climate the fleet actually works in.

WHAT TO WATCH

●  Watch for blind-spot lifts that recur job after job, because a repeated blind lift is a routine problem rather than a one-off.

●  Watch the position of the display in the cab. A good host in a bad position is one the operator will not read.

●  Watch the pre-lift check, because a camera that is not confirmed live may be showing a frozen frame.

●  Watch how the installation is approved locally, and keep the qualification documents with the machine records.

●  Watch the software path, because lifetime free software upgrades matter only if the fleet actually applies them.
