2 Ton Overhead Crane

This article aims to highlight every single detail and consideration required prior to the installation of such equipment, as well as the buying criteria list that can assist anyone in the decision-making process.

What Is a 2 Ton Overhead Crane?

A 2 ton overhead crane is a material handling machine used to lift and move materials from one point to another using a bridge that runs along a fixed horizontal path. The bridge carries a hoist that lifts the load vertically. The crane lifts up to 2000 kilograms of weight and runs on rails attached to the walls or ceiling of a building. This equipment is also called the EOT crane (Electric Overhead Traveling crane) when it uses an electric motor to hoist materials, perform cross-travel, and long-travel functions.

Unlike floor equipment, an overhead crane keeps the floor clear. It is the main reason many procurement managers prefer an overhead crane to a forklift or mobile crane for repetitive lifting operations inside a building.

Main Components of a 2 Ton Overhead Crane

• Bridge girder – horizontal beam facing the working place
• Hoist and trolley – lifting device which moves along the horizontal bridge girder
• End trucks – wheels that allow the bridge to run on the runway rails
• Runway beams – rails, usually attached to building columns or other supports
• Circuit breaker panel – controls hoisting speeds, travel directions, and disconnection safety devices
• Pendant or radio control – device for controlling the crane by an operator

When maintaining, I have observed that almost all operational problems are caused by two of these overhead crane parts: the worn hoist brake lining and the misaligned end trucks. These can be detected during a walk-around inspection.

Single Girder vs Double Girder: Which One Do You Need?

This is the first real decision point for a 2 ton capacity, so let's settle it with a direct comparison.

For a 2 ton overhead crane specifically, a single girder overhead crane is practically always the right choice. Double girder models are designed to serve heavier duty and more intense duty cycles, and applying them to a 2 ton workload is typically an unwise expenditure of steel.

One consideration that many buyers fail to take into account is the fact that single girder EOT crane pricing structures tend to fall into a better value range for lighter capacity applications like 2 tons, due to the reduced amount of structural steel and smaller runway system.

If your facility involves standard single shift operations, a single girder overhead crane is able to fulfill all of your lifting needs without sacrificing safety or lifting capabilities.

Overhead Crane Types You Should Know About

Prior to purchasing our 2 ton crane, you should know where it fits in the hierarchy of overhead crane types:

• Single girder EOT crane – economical, lightweight, designed for medium and light lifting
• Double girder EOT crane – for medium and heavy lifting, with spans up to four meters
• Gantry crane – mounted on legs, not building pillars
• Jib crane – has a rotating arm mounted on the wall or building pillars, used in combination with other overhead cranes
• Top running crane – bridge on the top of the runway rails
• Under running (underhung) crane – bridge is hanging from the bottom flange of the runway beam

Thus, your 2 ton capacity will most probably be secured by a top running single girder EOT crane, but if your building has low-profiled walls, an under-running configuration may be a suitable option.

How Load Capacity Works

One of the most common misconceptions I come across is that buyers believe that a 2 ton is a capacity which can only carry 2000 kg. However, 2 ton means that the maximum safe working load is 2 tons. Each crane is designed with a safety factor over this capacity and is tested to 125% of the maximum safe working load at the factory.

This is why they are NOT designed to work at absolute maximum capacity every time they are used. Working beyond the safe working load, even if it is only occasionally, will dramatically shorten the life of the hoist motor and wire rope.

Industry Applications of a 2 Ton Overhead Crane

The 2 ton rating is found in a surprisingly wide range of industries, all related to the fact that it covers the weight of many items typically handled in light or medium manufacturing:

• Automobile ancillaries lifting engines, gearboxes, and bodies
• Electrical switchgear manufacturers
• Machine tool workshops performing job work and fixtures
• Warehousing and distribution centers for materials or goods in pallets or crates
• Textile mill machinery and spares
• Food processing plant equipment and installations

By being able to cope with these varied applications, the 2 ton crane has shown that it has earned its place in so many industries by being capable of handling not just the average load, but also the occasional heavier one.

Benefits of Installing a 2 Ton Overhead Crane

There are several benefits of installing a 2 ton overhead crane including:

• It creates more floor space by removing the need for mobile lifting equipment
• It reduces manual handling-related injuries and downtime
• It has faster cycles for repetitive lifts
• It has reduced power consumption over larger capacity cranes
• It is simpler to install since it imposes less loading on building structure runways.
• They have a long service life span of up to 15 to 20 years if properly maintained.

Challenges when considering the purchase and installation of a 2 ton overhead crane

• The building structure’s ability to support the overhead crane runway beams should be evaluated before installation.
• The headroom and hook height must be physically measured to clear the tallest object being lifted.
• Operator training is required and should not be overlooked since most states require training for factory safety audits.
• Periodic third-party load tests are required by most states.
• Spares are not often interchangeable among different manufacturers.

Buying Guide: Checklist

Refer below before finalizing your overhead crane manufacturer and specification sheet

• Confirm exact span (bay width) of your building
• Measure available headroom and hook approach clearance
• Single girder or double girder?
• Duty class (this shows how many lifts per hour is sustainable)
• Pendant, radio remote or cabin operated?
• Is it compliant to Indian BIS standards?
• Ask about the response time for after-sales service and spares stocking
• Written confirmation of load test results, structural design calculations etc

I have seen many clients skip step 8 above and then during factory inspection a year later have compliance issues due to lack of adequate documentation.

Common Mistakes Buyers Make

• Prioritizing quoted overhead crane prices over duty class, steel grade and headroom requirements specifications leading to redesigns
• Incorrect duty cycle computations resulting in motor burnout during high-frequency operations
• Neglecting operator training posing significant safety and legal implications
• Failure to confirm whether the overhead and gantry crane manufacturer in India has a manufacturing unit or operates as a trading agent

Maintenance Practices For Longevity

• Quarterly inspection of wire rope for fraying and kinking
• Lubrication of girder rails, trolley wheels, and roller bearings per the recommended maintenance schedule
• Testing limit switches and safety brakes every three months
• Keeping the electrical panel free from dust, especially in harsh environments
• Annual load testing by an independent agency and statutory compliance audits.

Expert Tips From the Field

When I've done duty cycle comparisons for different plant types for clients in the past, I've noticed that facilities that run two shifts require a higher duty class than is spec'ed, even on the same 2 ton capacity.

You don't want to get talked into the base duty class by the vendor because they want the lower cost option. Industrial engineering references (and those that follow ISO crane design standards) suggest you base the purchase on the frequency of lifts rather than the most basic specification.

This will impact the life of the gears in the gearbox, more than almost any other consideration mentioned in the specifications list.

Times Krane: Manufacturing You Can Rely On

Times Krane has been in the business of building overhead crane manufacturers across Indian industrial belts for years. The company provides single girder and double girder EOT cranes that are manufactured to match the exact duty cycles specified by the customer instead of following generic catalogues. Each unit that is shipped from the Faridabad facility has its structure and load tested before delivery.

With regard to 2 ton overhead crane, it is always a good idea to consult a professional manufacturer that can take care of your requirements at the design stage instead of having to rework the whole project at a later stage.

Key Takeaways

• A 2 ton overhead crane presents the most common lifting capacity for small and medium-sized Indian factories
• Therefore, a single girder configuration is usually sufficient for the task
• The duty of the overhead crane should always correlate with the anticipated usage (frequency of lifting), and not only the lifting mass
• The headroom, span, and building structure must be considered prior to ordering the equipment.
• Periodic maintenance and third-party load testing are crucial for the continuous conformity of the overhead crane
• Moreover, choosing an overhead crane manufacturer with proven experience and in-house fabrication facilities is vital for reducing risks.
