The mechanical Yato lifting and installation tool is designed for precise lifting, positioning, and leveling of heavy objects such as plasterboards, doors, windows, and furniture in industrial environments. The device operates with a lever and ratchet mechanism, which converts the movement of the handgrip into a controlled vertical lifting force. Its operating range of 10–160 mm allows components to be lifted from almost floor level to the desired installation height without additional tools.

The tool's body and lifting mechanism are made of hardened steel, ensuring structural rigidity and a long lifespan in demanding professional use. The steel lifting foot is thin to allow it to be inserted into narrow gaps, yet wide enough to ensure stable support. The handle is padded with thick cellular rubber and ergonomically designed to reduce strain on the user's hand during repetitive lifting tasks, and a mechanical release lever allows for controlled and safe lowering of the load.

The device's 45 kg static lifting capacity is optimized for one-handed installation work, where the other hand needs to remain free to guide the object being installed. This feature makes the tool essential, for example, for installing kitchen cabinets and washing machines, fitting door leaves to hinges, or supporting the bottom edge of plasterboard walls. By using multiple devices simultaneously, lifting capacity and load stability can be significantly increased.

This mechanical hand jack is maintenance-free and operates without electricity or hydraulics, which increases its reliability on construction sites. The tolerances of the steel structure are designed with minimal wear in mind, and the lifting mechanism is better protected from dust and dirt than its hydraulic counterparts. Objectively evaluated, the device offers a cost-effective and ergonomic solution for replacing heavy physical lifting in installation work.

Intended Use and Suitability:

The product is intended for construction, installation, and logistics sectors where precise load control and ergonomic working methods are required.

• Construction and Interior Installations: Precise positioning and support of plasterboards, partition elements, doors, and windows during installation. The thin lifting foot allows access under the board without clearance.
• Furniture Installations: Lifting and leveling heavy cabinets, worktops, and furniture at the installation site.
• Tiling Work: Support and fine adjustment of the bottom row of tiles in wall tiling, ensuring a perfect horizontal level.
• Logistics and Maintenance: Fine-tuned lifting of machines, equipment, or heavy boxes for transfer or maintenance in confined spaces.

• Lifting foot thickness: < 5 mm (estimated, allows access into narrow gaps).

Yato Lifting and Installation Tool User Manual:

Follow these steps to ensure safe and efficient use of the device:

1. Preparation: Ensure there is sufficient clearance (at least 10 mm) between the object to be installed and the floor to place the lifting foot. Inspect the tool for damage before use.

2. Positioning: Insert the steel lifting foot of the tool completely under the object to be lifted. Ensure the device is vertical and on a stable surface.

3. Lifting: Squeeze the tool's handles repeatedly. The ratchet mechanism lifts the object steplessly with each squeeze. Continue until the desired height is reached. Monitor load stability during lifting.

4. Lowering: Support the load if necessary and press the mechanical release lever in a controlled manner. The load will lower under its own weight. Release the foot from under the object after lifting.

Warnings:

Read and understand the following safety warnings:

• Do not exceed the maximum load: The maximum static load of the device is 45 kg. Overloading can lead to mechanical failure and the load falling.
• Use only on a flat surface: Ensure the device is firmly on a stable and non-slip surface.
• Do not use for unstable loads: Ensure that the object being lifted is balanced and will not tip over during lifting. Use multiple tools if necessary.
• Keep hands away from pinch and lowering areas: A falling load can cause severe injuries.

Frequently Asked Questions, FAQ:

Answers to technical questions from professionals:

Question: Can this tool lift full-size plasterboards when installing them on a wall?

Answer: Yes, the device is excellent for lifting and supporting the bottom edge of a plasterboard. When the board is supported from the top edge by hand, the 45 kg lifting capacity is typically sufficient to manage the weight of one plasterboard during installation.

Question: How precisely can the lift be performed?

Answer: Lifting is done steplessly using the ratchet mechanism. Each squeeze of the handle lifts the load a few millimeters at a time, allowing for very precise positioning, such as leveling kitchen cabinets.

Question: Can multiple tools be used simultaneously to lift a heavier load?

Answer: Yes, by using, for example, two tools, the lifting capacity theoretically increases to 90 kg. However, it must be ensured that the load is evenly distributed between both devices.
