Electric Overhead Traveling Crane (EOT Cranes)

EOT stands for Electric Overhead Traveling. Unlike mobile cranes or tower cranes that are floor-based, an EOT crane runs on elevated runway rails fixed to your building, also known as bridge cranes. Basically, they help keep your floor clear and offer full coverage of the working area below the runway.

Start with your heaviest single lift requirement and add a 20–25% safety margin. Also consider your lift frequency, a crane that lifts 10 times a day needs a higher duty class than one used 10 times a week. We help you calculate the right specification during the consultation phase.

Yes, you can safely use EOT cranes indoors near workers. Our experts ensure proper installation, operator training, and check on safety systems. In fact, modern EOT cranes feature overload protection, limit switches, anti-collision devices, load displays, and emergency stop systems.

It might depend on your requirement, i.e, whether you are looking for standard cranes (1T–20T single girder), heavy-duty or custom cranes.

At Reva cranes, our products do not involve cheap components. Our gearboxes are manufactured in-house using low-carbon alloy steel pinions hardened to 55-60 HRC in our own heat-treatment plant, a process most crane manufacturers outsource or skip entirely. We use VVFD drives as standard across our range, which extends motor life and reduces energy costs. These choices increase the manufacturing cost but reduce your total cost of ownership over the crane's 20–30 year operating life. Remember, a crane that costs 15% more upfront but runs without major intervention for 25 years is significantly cheaper than a cheaper crane that requires a gearbox replacement at year seven.

Yes. After an initial technical consultation to establish your specifications, load capacity, span, duty class, lift height, and building details, our engineers produce a detailed commercial proposal that itemises the major cost components. We do not issue indicative prices without understanding the application, because an EOT crane is not a commodity product: a 10T crane for a light engineering workshop and a 10T crane for a hot metal foundry are fundamentally different machines.

Total cost of ownership for an industrial crane includes the purchase price, installation, energy consumption, annual maintenance, spare parts, and unplanned downtime costs. Reva's in-house design approach specifically targets the three highest ongoing costs: energy (through VVFD drives that consume proportional to actual load), maintenance (through robust gearboxes, sealed components, and predictive maintenance support), and downtime (through multiple safety interlocks and rapid spare parts availability). While we can share application-specific data during consultation, well-maintained Reva cranes in medium-duty applications consistently operate for 20+ years with minimal major component replacement.

Our PAN-India service network is structured for rapid response. For customers on a preventive maintenance agreement, our team is already familiar with your crane and can typically diagnose issues remotely before a site visit is needed. Because Reva manufactures critical components in-house, including gearboxes, which are the most common failure point in long-service cranes, spare parts are available from our Faridabad plant without the lead times associated with imported or third-party components. For emergency breakdowns, please contact our service helpline directly for current response time commitments in your region.

Reva cranes are specified with multiple overlapping protection systems: VVFD motor protection (single-phasing, phase-sequence fault, overcurrent, and impact sensing), overload protection via load cells, hoisting and travel limit switches, anti-collision devices where multiple cranes share a bay, and emergency stop systems. The drive system's built-in motor protection means many potential fault conditions are detected and the crane is safely stopped before damage occurs, which is very different from an older contactor-based crane that may run to failure. We also offer remote diagnostics and predictive maintenance support as part of our after-sales programme.

Chronic maintenance issues in EOT cranes typically trace back to three root causes: undersized or inappropriate duty class for the application, low-quality gearboxes or motors, or deferred maintenance accumulating into structural problems. When customers come to us with a crane that has become unreliable, we start by understanding the application, what it's lifting, how many cycles per day, what the environment is like. If we're replacing an existing crane, we engineer the new crane to the actual duty class the application demands, not a lower class that reduces the initial price. We also offer crane modernisation and refurbishment services if the existing structure is sound but components need upgrading.

Lead time depends on three variables: crane type and capacity, degree of customisation, and the current production schedule at our plant. As a general reference: standard single-girder cranes in the 1T-20T range have shorter lead times than heavy-duty double-girder or special-purpose cranes. During the proposal stage, our project team issues a formal schedule with manufacturing milestones, factory acceptance test date, and installation timeline. We build to that schedule with dedicated project management, delays caused by scope changes are flagged early so decisions can be made before they affect the delivery date.

We take production commitments seriously, and our track record with industrial customers in time-critical projects, including railway workshops and steel plant startups, reflects this. When a hard deadline is established at order stage, it drives the manufacturing schedule, not the other way around. We recommend involving our engineers early in the civil/structural design phase, as crane runway beam specifications must be finalised before building construction progresses, and late changes at that stage are the most common source of project delays.

Reva cranes are designed and manufactured in compliance with the relevant Bureau of Indian Standards (BIS) codes, including IS 3177 (Code of Practice for EOT Cranes and Gantry Cranes), IS 807 (Design, Erection and Testing of Cranes and Hoists), and applicable FEM standards for duty class classification. All cranes are load-tested at 125% of rated capacity before despatch, and third-party certification is available and provided as standard on all our cranes. Compliance documentation is included in the delivery package.

Yes. Our Flame Proof Cranes and Hoists range is engineered for use in potentially explosive atmospheres, chemical plants, paint shops, solvent storage areas, and similar environments. All electrical components in a flame-proof crane are rated for the relevant zone classification, and the crane is designed and tested to meet the applicable ATEX or IS standards for your application. Specify your zone classification and hazardous substance category when enquiring.

The energy saving depends on the duty cycle of your crane, how often it lifts, at what percentage of rated load, and over what distances. A VVFD (Variable Voltage Variable Frequency Drive) system consumes energy proportional to the actual load being lifted and the actual speed of operation, rather than drawing full motor current at every start. In a medium-to-heavy duty application with multiple lifts per hour, energy savings of 25-40% compared to slip-ring motor systems are commonly observed. Beyond energy, VVFD systems eliminate the mechanical wear on resistors and contactors that make older cranes expensive to maintain, and they provide smoother load handling that reduces stress on the structure and the hook load.
