7. Boom Lifts (Aerial Work Platforms)

• Description: Boom lifts are hydraulic lifts with extendable arms that can reach great heights. These lifts can move vertically and horizontally, offering greater flexibility in accessing areas that are difficult to reach.

• Applications: Construction, maintenance, tree trimming, and exterior building work.

8. Hydraulic Jacks

• Description: Hydraulic jacks are smaller, portable devices used to lift heavy objects such as vehicles or machinery. They use hydraulic force to lift loads with minimal effort from the user.

• Applications: Vehicle lifting for maintenance, heavy equipment repair, and industrial applications.

9. Warehouse Lifts (Goods Lifts)

• Description: These lifts are designed to transport goods vertically between different levels of a warehouse or manufacturing facility. They typically use hydraulic systems to lift heavy goods or products.

• Applications: Warehouse operations, goods transportation, and manufacturing plants.

10. Elevated Platforms (Hydraulic Lifts for Construction)

• Description: These lifts are used in construction sites for lifting materials or equipment to higher levels. They can be vertical lifts or mobile platforms that can be moved around the construction area.

• Applications: Construction, building repairs, or installation work.

11. Vertical Reciprocating Conveyor (VRC)

• Description: These are vertical lifts used for material handling, often in industrial and commercial applications. VRCs use hydraulic or mechanical systems to lift and lower materials between floors.

• Applications: Industrial material handling, manufacturing plants, warehouses.

12. Hydraulic Cylinders Lifts

• Description: These lifts use hydraulic cylinders to lift heavy loads. They are often used in specialized applications where vertical lifting is needed with high force.

• Applications: Heavy machinery, construction, and mining.

Each type of hydraulic lift has a specific design suited for its unique application, whether for personal use, material handling, or construction purposes.
