05 · CHASSIS FITMENT REFERENCE
Fitment is reviewed before supply.
The image below is an illustrative chassis-fitment reference, not a customer installation case. AOZI checks available mounting space, chassis drawings, bracket layout and required stroke before confirming the supply configuration.

Replace the manual jack at its existing mounting position.
On most compatible trailer and caravan chassis, the manual jack can be removed and the AOZI electric leg fitted at the original position using the existing bolt pattern—without drilling, cutting or welding. A small number of chassis designs require confirmation or a model-specific bracket before supply.
- Existing mounting position
- Bolt-on mechanical replacement for most compatible chassis
- Special chassis reviewed before supply
Real workshop installation photographs. Electrical connection and controller setup must follow AOZI installation instructions.
07 · PATENT DOCUMENTATION
Two Chinese utility model patents support the product design.
Both patents were granted to DE ZHOU AO ZI CAMPING EQUIPMENTS CO., LTD. Patent certificates are available for review.

CN 216184744 U · 05 Apr 202208 · TECHNICAL FAQ
Questions buyers usually confirm before quotation.
Is this a four-leg system?
Yes. The reference configuration is one complete system with four coordinated electric legs.
Can it level a caravan automatically?
The controller uses sensor feedback to coordinate the legs for automatic leveling and stabilization.
What is the rated load?
The confirmed rated load is 800 kg per leg and 3,200 kg combined for the four-leg system.
Does it fit every chassis?
It fits most common chassis layouts. On compatible models, the original manual jack is removed and the electric leg is bolted into the existing position without drilling, cutting or welding. A small number of chassis designs require confirmation or a model-specific bracket.
Can the system lift the whole vehicle?
The system is specified for leveling and stabilization. It is not presented as a whole-vehicle lifting or wheel-lifting system.
What information is needed for a fitment review?
Send the vehicle model, maximum vehicle mass, chassis drawing or available mounting-space dimensions, required stroke, annual quantity, destination country and OEM-branding requirement.
