Handling heavy metallic loads has always been a challenge across industries. Traditional lifting methods often demand more time, labour, and safety precautions. However, with the introduction of Permanent Magnet with Dolly systems, moving and handling ferrous materials has become safer, faster, and far more efficient. These innovative tools combine the power of magnetic lifting with the mobility of wheels, creating an easy-to-use solution for warehouses, factories, and workshops.

This guide will take you through everything you need to know about magnetic lifters with wheels for lifting manhole covers, their benefits, working mechanisms, applications, and why they are becoming a trusted choice for material handling.

What is a Permanent Magnet Dolly?

A Permanent Magnet Dolly is a hybrid lifting and moving device designed to make handling heavy metal loads easier. It integrates a permanent magnet with a wheeled dolly, enabling workers to lift and transport ferrous materials such as steel sheets, plates, manhole covers etc. with minimal effort.

Unlike traditional lifters that need electricity or hydraulics, these devices rely on the permanent magnet’s strong magnetic field to grip materials securely. With the dolly mechanism, you can simply tilt and move the load smoothly without straining.

Why Choose a Magnetic Lifter with Wheels for lifting manhole covers?

A magnetic lifter with wheels offers both stability and convenience. Here’s why industries are switching to this modern solution:

Safety First – Using a permanent magnet dolly minimises injuries caused by heavy manual lifting. Workers stay safe as the device securely grips and moves the load without strain.
Efficient Handling – This tool lifts and transports manhole covers in one smooth action. There is no need to find the right key that fits into the key slot since the magnet attaches directly onto the cover’s surface. It saves time and effort
No Power Source Needed – The dolly uses strong permanent magnets that don’t need power to function. This makes it reliable even in areas without electricity or during power cuts.
Durability – Made with tough magnets and heavy-duty wheels, it can handle regular industrial use. The design ensures consistent performance over many years.
Cost-Effective – By combining lifting and moving in one unit, it lowers the need for extra workers or machines. This results in long-term cost savings for businesses.
Portability - The wheeled lever / dolly can be easily folded for easy transport

How Does a Permanent Magnet Dolly Work?

The mechanism is simple yet effective:

The permanent magnet creates a strong magnetic field to grip metal surfaces.
Once attached, the wheeled dolly allows workers to tilt or push the load to the desired location.
Many models come with a release switch, which makes detaching the magnet quick and safe.

This smart design combines lifting, gripping, and moving in a single step, making it ideal for busy industrial settings.

Key Benefits of Using a Permanent Magnet with Dolly

1. Improved Safety Standards

Workers no longer need to strain their backs or risk injuries when moving heavy loads. The dolly does the heavy lifting.

2. Increased Productivity

By reducing the handling time, companies can complete more tasks in less time.

3. Reduced Operational Costs

No need for complex lifting machinery or extra manpower.

4. Versatility

Besides manhole covers, it can also be used for handling steel plates, beams, and other ferrous components in workshops, construction sites, and warehouses.

5. Eco-Friendly

Since it doesn’t require electricity or fuel, it is energy-saving and sustainable.

Permanent Magnet Dolly vs manual Lifting Methods

Feature	Permanent Magnet Dolly	Manual Lifting w/ keys
Power Source	None needed	None needed
Safety	High	Low
Efficiency	High – lift & move	Moderate – needs more than one person to lift most covers
Mobility	Easy with wheels	Limited

Clearly, the Permanent Magnet with Dolly offers better overall handling, especially in fast-paced industrial environments.

Maintenance and Care Tips

To ensure longevity and safe operation, follow these tips:

Keep the magnet clean – Avoid dust, oil, or rust build-up.
Inspect wheels regularly – Ensure smooth rolling and no damage.
Check lifting capacity – Always use within the recommended load limit.
Store properly – Keep it in a dry, clean place when not in use.

Hydraulic Manhole Lifter UAE

Along with magnetic handling solutions, industries also rely on tools like the hydraulic manhole lifter UAE for safe and efficient lifting of heavy covers. Combining such specialised equipment ensures a well-rounded approach to workplace safety and efficiency.

Key Takeaways:

A Permanent Magnet with Dolly is a powerful tool that combines magnetic lifting and wheeled mobility.
It eliminates the need for electricity or hydraulics, making it cost-effective and eco-friendly.
Industries like construction, warehousing, and manufacturing greatly benefit from its use.
It enhances safety, productivity, and efficiency while reducing labour costs.
Proper care and maintenance ensure long-term durability and reliable performance.

FAQs:

Q1: What is the weight capacity of a Permanent Magnet Dolly?

Techniche supplies permanent magnets with capacity from 400-1000kg and wheeled levers / dollies with capacity of 600kg. These are sufficient to lift most of the commonly found manhole covers

Q2: Can it be used on non-metallic surfaces?

No, it works only with ferrous metals like steel and iron.

Q3: Does it require electricity to operate?

No, it works with permanent magnets and doesn’t need electricity.

Q4: Is it safe for long-term use in industries?

Yes, when used within its load limit and with proper care, it is extremely safe.

Q5: How is it different from a hydraulic manhole lifter?

A hydraulic manhole lifter is designed for lifting manhole covers, while a magnetic lifter with wheels is for handling ferrous materials. Both serve specific lifting needs.
