Reaching the load from the available parking position
A load beside the parked truck is the kind of access problem that makes a rotator worth considering. The boom can turn towards working positions around the truck when the available approach does not put the target behind it. KEEYAK lists 360° rotation for the Rotator Wrecker family; the load permitted at any one position depends on the chart and support conditions for the truck in the quotation. KEEYAK Rotator Wrecker
The next question is the onward tow. KEEYAK's Integrated Wrecker reference lists towing and wheel-lift ratings alongside the recovery boom, making it a starting point for that comparison. For either family, highway towing suitability depends on the assembly actually installed and the target load it supports. KEEYAK Integrated Wrecker
Lift ratings and towing ratings answer different questions
A boom lifting figure describes work done by the boom. A towing figure concerns the towed vehicle, whereas the wheel-lift figure concerns the load that the wheel lift supports. All use tonnes, so comparing the largest number on each product page can conceal a difference in function. The catalog labels below keep those functions visible.

| Equipment duty | Rotator Wrecker catalog entry | Integrated Wrecker catalog entry |
|---|---|---|
| Lifting with the boom | Rotator Lifting Capacity: 30 to 50 t | Boom Lifting Capacity: 3 to 20 t |
| Turning and extending the boom | Rotation: 360°; Boom Extension: 3 to 10 m | Boom Extension: 1.2 to 3 m; rotation is unspecified in this table |
| Towing and supporting the lifted wheels | This table gives no separate towing or wheel-lift values | Towing Capacity: 3 to 40 t; Wheel Lift Capacity: 3 to 10 t |
| Pulling with the winches | Winch Capacity: 15 to 25 t (dual) | Winch Capacity: 4 to 15 t (dual) |
| Space occupied by the supports | Outrigger Span: 5 to 8 m | This table gives no support span |

These are family ranges, so their upper endpoints are not a specification for one truck. The source does not confirm a build combining maximum lift with maximum extension and support span. The word dual leaves the load represented by the winch figure unspecified; it gives no authority to add winch capacities.
The quoted truck needs its own working limits
Jerr-Dan publishes an operational load chart for its JD35/40 rotator and separate underlift material. That separation shows why a buyer needs documents for each duty. Those documents describe Jerr-Dan equipment and cannot rate a KEEYAK truck. Jerr-Dan JD35/40 rotator
The boom assessment is useful for comparison only when the supplier identifies the working position and the supports that will be deployed. The towing assembly and winches need separate entries. Axle loads on the completed truck require assessment for both travel and towing: a large boom rating alone cannot establish either arrangement. KEEYAK Rotator Wrecker KEEYAK Integrated Wrecker
Daily rear-access towing with occasional side-access jobs
Suppose, for an illustrative fleet brief, that most calls involve towing a vehicle with a clear rear approach. On a smaller group of jobs, the only parking position leaves the target beside the truck. The integrated wrecker is the starting point for the routine workload; the side-access jobs explain why the fleet would also assess a rotator. Their frequency helps frame the purchase decision, but their existence alone cannot establish that a particular model can perform them.
A proposed configuration comes off the shortlist if its required supports cannot fit the representative site. Where they fit, the supplier still needs to assess the actual target and boom positions. This hypothetical brief provides neither target mass nor load-chart values, and it gives no incident procedure. It is not a KEEYAK project result.
A purchase brief covering recovery and the onward tow
The supplier needs to understand the vehicles the fleet commonly recovers and the sites where it works. Actual masses and axle loads connect the target vehicles to the equipment ratings; a representative sketch connects the target position to the truck's parking position. Together, they support an answer about reaching the load and a separate answer about the equipment needed to tow it onward.
- Routine towing and jobs needing another boom approach are described separately.
- Site sketches identify access restrictions and the space available for supports.
- The quotation includes charts for the proposed model and ratings for its towing equipment.
- Unresolved ground and traffic conditions, along with attachment questions, go to the qualified recovery team.
