Height-Adjustable Power Toolbox with Hydraulic Lift and Built-in Charging

The problem

Mechanics and technicians often spend hours bending over or reaching up because their tool storage does not match their working posture. Fixed-height toolboxes cause physical strain, while adding separate lifting equipment is cumbersome and takes up floor space. Additionally, traditional boxes lack integrated power solutions, forcing workers to run extension cords across the shop floor, which creates trip hazards and disorganized cable management. Small tools also tend to get lost in unpartitioned trays, slowing down retrieval time during critical repairs.

The solution

The patent describes a toolbox where the main body is elevated by hydraulic cylinders (3) located at the four corners of the lower end. Each cylinder connects to a cushion block (4), allowing the operator to adjust the height of the entire unit smoothly. The base rests on universal wheels (2) equipped with brake devices for stability during use.

Inside the bottom cavity, a battery component (5) stores energy, managed by an electromagnetic valve (6). A control box (7) on the outer wall houses the controller, which electrically connects to the battery, valve, and internal sockets (11). The upper section contains storage drawers (8) with a specialized tool storage area (9). This area features an instrument storage groove (91), a first storage trough (92) divided by a partition board (10), and a second storage trough (93). The box lid (12) is hinged and includes hooks (13) for extension tools, a collection bag (14), and an LED illumination lamp (15).

Who it is for

• Automotive Repair Shops: Mechanics who need to access engine bays at varying heights without using jack stands for their tools.
• Industrial Maintenance Teams: Technicians requiring mobile power sources and organized storage for frequent machine inspections.
• Field Service Engineers: Professionals who need a self-contained workstation with lighting and charging capabilities for remote sites.
• DIY Enthusiasts: Homeowners looking for a premium, ergonomic garage setup that reduces clutter and improves workflow efficiency.

How it works

The main parts

Operating Steps

1. Positioning: Roll the toolbox to the work site and engage the wheel brakes.
2. Height Adjustment: Activate the hydraulic system via the control box to raise the box body to the desired ergonomic height using the corner cylinders.
3. Access Tools: Open the storage drawer to retrieve tools from the partitioned troughs and instrument grooves.
4. Power Up: Plug cordless tools or devices into the internal sockets powered by the battery component.
5. Lighting: Switch on the LED lamp on the lid if working in dim conditions.
6. Stowage: Return tools to their specific slots; hang extensions on the lid hooks. Lower the unit and move to the next location.

Applications

Automotive Engine Bays

Technicians can raise the toolbox to align with open hoods, keeping heavy wrenches and diagnostic tablets within arm’s reach without bending, reducing fatigue during long repair sessions.

Industrial Machine Inspection

In factories where maintenance crews move between machines of different heights, this unit adjusts to the specific access point, providing immediate power for sensors and lighting for dark crevices.

Field Electrical Work

Electricians benefit from the integrated sockets to charge multimeters or power temporary lights, while the organized drawers prevent losing small fuses or connectors amidst dust and debris.

Garage Workshops

For home mechanics, the unit serves as a central hub. The LED light aids in visibility under cars, and the push-pull bar allows easy movement around tight garage spaces.

Where it is less suitable

• Heavy-Duty Construction Sites: The hydraulic and electronic components may be vulnerable to extreme impacts and mud common in rough construction environments compared to rugged steel carts.
• Static Storage Only: If height adjustment is never needed, standard fixed tool chests are more cost-effective and have fewer mechanical parts to maintain.
• High-Capacity Tooling: The partitioned drawers are designed for organization; very large tools like sledgehammers or long pry bars may not fit in the specified grooves.
