4t Foldable Leveling Jack

The 4T foldable leveling jack produced by Homall manufacturer has a single-point rated load capacity of up to 4000KG. It also supports customized lightweight load specifications as needed, and is compatible with the vast majority of small and medium-sized modified vehicles on the market. Different from fixed legs, this product adopts a foldable storage structure and is equipped with 12V/24V universal vehicle DC power supply. It features full mechanical and electrical lifting, without hydraulic oil circuit configuration. The overall structure is simple and the installation adaptability is wide. It perfectly solves the industry pain points of traditional leveling equipment being bulky, prone to oil leakage, and having poor versatility. It is a lightweight upgrade solution for outdoor parking and special operation vehicles.

Product Function

1. Correct the vehicle's levelness to ensure the precise operation of precision vehicle-mounted equipment.

In outdoor operation areas, the ground is often uneven and the slope is inconsistent. When the vehicle parks, it is prone to tilt and shift, which directly leads to deviation in satellite antenna alignment, distorted environmental monitoring data, and failure of command equipment calibration. This folding leveling leg can quickly complete multi-point balanced support, fine-tune the vehicle's level angle, firmly lock the equipment's working benchmark, and ensure that communication, monitoring, and command equipment operate with zero error and stability.

2. Foldable and compact for easy storage without blocking the chassis, preserving the vehicle's driving performance.

Compared to vertical fixed legs, the folding structure of the 4T foldable leveling jack can be fully retracted and stored against the chassis during driving, without reducing the ground clearance and not affecting the vehicle's ability to travel on mountain roads and uneven surfaces, achieving the dual effects of "unobstructed driving and stable parking".

3. Oil-free and clean operation, suitable for various professional special vehicles.

The pure electric mechanical lifting structure completely eliminates the problems of hydraulic oil leakage and oil splashing, and will not contaminate the vehicle chassis or the operation site. It is suitable for medical rescue vehicles, environmental monitoring vehicles, integrated command vehicles, and other professional models with strict requirements for operation cleanliness.

Application purposes

1. Leveling for outdoor parking of recreational vehicles and camper vans

2. Stable parking for small and medium-sized special operation vehicles

3. Stable support for mobile service equipment platforms

4. Auxiliary support for vehicle maintenance and repair scenarios

5. Auxiliary operation for temporary outdoor projects in the wild

Actual performance tests

1. Rated load static load-bearing test

A single leg is loaded with 4000KG and subjected to static pressure for 72 hours. The leg shows no bending deformation, the gear transmission has no slipping, and the body does not sink or shift. The folding structure is firmly locked, the load-bearing structure is stable and reliable, fully meeting the long-term parking load requirements. For special lightweight models, a customized load version also passes continuous load-bearing tests and is suitable for various niche modified chassis.

2. High and low voltage compatibility test

Continuous up and down tests of 500 times under 12V, 24V vehicle standard voltage and slight voltage fluctuation conditions. The equipment starts and stops smoothly, the up and down movement is uniform without lag, the motor does not overheat or report faults, and it is compatible with unstable vehicle voltages in complex outdoor power supply environments.

3. Folding opening and closing durability test

Repeated folding and storage, and unfolding and supporting cycle tests for 1000 times. The folding shaft shows no loosening, the locking structure is precise. The storage fitment and unfolding support angle remain consistent. The mechanical structure durability meets the requirements for long-term high-frequency usage scenarios.

4. Outdoor environmental adaptability test

Continuous operation tests in humid, dusty, and alternating high and low temperature outdoor environments. The transmission components of the body have stable dust-proof and moisture-proof performance, no jamming, no rusting, and will not experience lift-up failure due to the harsh outdoor environment. It is suitable for all-weather outdoor parking operations.

5. Sloping ground leveling accuracy test

Simulate parking on 3°-8° uneven slopes in the wild. The 4T foldable leveling jack can quickly complete multi-point adaptive leveling. The body's inclination error is controlled within the industry standard range, effectively correcting the body's deviation, ensuring the antenna and monitoring equipment work accurately, and fully meeting the precision requirements for special vehicle operations.
