Frequently asked questions
Looking for a quick, clear answer? Here you’ll find the most common questions about E-Crane® technology, applications, service and ownership.
For your convenience we’ve split up all questions into categories.
General
All E-Cranes are equipped with an electric main motor. If shore power is not available (for example at remote quays or on crawler-mounted units), a diesel generator can be integrated as an onboard power source. The generator can be supplied by E-Crane or by the customer.
No. E-Crane offers a wide range of stationary and mobile configurations, including fixed pedestal installations, free-standing units on outriggers, rail-mounted cranes, crawler-mounted solutions and floating installations on barges, dredgers and ships.
Yes. Every E-Crane ever sold has been assembled, commissioned and delivered by E-Crane’s own experienced service and installation teams.
Steel structures are manufactured in Poland at E-Crane’s steel construction facility. Final assembly, testing and commissioning take place in Belgium. Cranes are typically shipped via the ports of Antwerp or Zeenrugge
Technical specifications
The smallest E-Cranes are in the 700B Series. Depending on the model and configuration, their outreach ranges from 24.8 m to 31.7 m.
Maximum outreach depends on the crane series:
- 700 Series: up to 31.7 m
- 1000 Series: up to 38.2 m
- 1500 Series: up to 38.2 m
- 1800 Series: up to 42.1 m
- 2000 Series: up to 42.1 m
- 3000 Series: up to 45.0 m
- 4000 Series: up to 47.8 m
Installed power depends on the crane series. Within a given series, all cranes use the same electric main motor:
- 700 Series: 132 kW / 180 hp
- 1000 Series: 200 kW / 270 hp
- 1500 Series: 250 kW / 335 hp
- 1800 Series: 450 kW / 600 hp
- 2000 Series: 450 kW / 600 hp
- 3000 Series: 630 kW / 845 hp
- 4000 Series: 750 kW / 1006 hp
The “sweet spot” is the part of the crane’s working range where it operates during most cycles (typically more than 90%). In this zone, the crane delivers its highest Safe Working Load (SWL) and the best loading and unloading efficiency.
Energy & power
The crane’s electric main motor typically runs on 400 VAC / 50 Hz or 480 VAC / 60 Hz. If your site provides a different supply (such as medium or high voltage), E-Crane can include the appropriate transformer as part of the solution.
Mounting & mobility
No. E-Crane cranes are available on crawlers, rails, pedestals, and barges. Rubber-tyred configurations are not part of the E-Crane product range.
For new installations, E-Crane recommends true crane rails (A100 or an equivalent profile). If you already have rails on site, E-Crane can adapt the travel wheels to match the existing rail profile.
- Rail-mounted cranes typically travel 30–60 m/min (standard speed: around 40 m/min).
- Crawler-mounted cranes typically travel around 0.5–1.2 km/h, depending on crane size and configuration.
There is no single fixed value. The maximum slope depends on crane size, ground conditions and safety margins. The exact limit is defined per project during the engineering phase.
Standards & compliance
E-Crane’s steel structure is manufactured under an ISO 9001 certified quality system. The crane design and structural calculations follow the ISO 13001 series for crane design.
There is no direct one-to-one U.S. equivalent of EN 13001. Functionally, however, comparable requirements are achieved by combining several U.S. standards.
Europe:
- EN 13001: design and structural calculations
- EN 15011 / EN 60204-32: safety, inspection, and maintenance
United States:
- CMAA 70 / 74: crane design, classification, and calculations
- ASME B30.2 and AISC standards: safety, inspection, and maintenance
Service & maintenance
E-Crane offers service contracts tailored to your operation. Options range from Full Maintenance Contracts (FMC) to periodic inspection programs and on-demand support, including remote assistance, to help keep uptime predictable.
Yes. Regular oil sampling is recommended as part of preventive maintenance. It helps monitor oil condition, detect early wear, and reduce the risk of unexpected component failures.
This depends on the specific component:
- Main hydraulic pumps: recommended overhaul after approximately 15,000 to 20,000 operating hours. E-Crane also performs regular pump leak tests that help in better planning a sheduled pump overhaul.
- Boom cylinder seals: typically 5,000 to 8,000 hours.
- Counterweight cylinder seals: typically 10,000 to 12,000 hours.
Yes. Depending on crane size, a service crane is included as standard equipment or can be added as an option.
Attachments & interfaces
Yes. E-Crane offers mechanical quick-release systems for all series. Fully automatic quick-release systems are currently available for the 700 to 2000 Series, depending on crane size and application requirements.
E-Crane can supply a wide range of attachments, such as buckets, grabs, grapples, rotators, spreaders, lift beams, big-bag spreaders, hooks, magnets, and quick-disconnect systems. If an attachment can be integrated safely, it can usually be delivered as part of the solution.
No. You can source attachments from your preferred suppliers. E-Crane will provide the necessary interface specifications to ensure compatibility and safe operation.
Digital tools
An E-CARE App account is provided free of charge. There are no costs associated with creating or using an E-CARE account.
Transport & safety
The outrigger feet are secured with clamps that are welded to the deck. Additional lashings are then applied to keep the crane safely restrained during marine transport.
Yes. For rail-mounted cranes, dedicated tie-down points are provided and aligned with the quay infrastructure. Storm pins can also be included as part of the system. For barge-mounted cranes, E-Crane typically supplies a deck-welded stowage construction that allows the crane to be secured using the quick-disconnect device.
No. E-Cranes have a heavy, compact design with limited wind-catching surface, which helps reduce the risk of overturning or wind-related structural damage in extreme conditions.
Coating & corrosion protection
E-Crane uses industrial coating systems that are selected to match the operating environment, including marine and highly corrosive conditions. For example, a C5-M coating system (ISO 12944) typically uses a durable multi-coat build-up with a zinc-rich primer, an epoxy intermediate layer, and a UV-resistant polyurethane topcoat, with total dry film thickness specified for the project. With the right specification and routine maintenance, the coating can protect reliably for many years. References from port and offshore environments are available on request.
Custom paint pricing depends on the selected coating system, required layer thickness, color scheme, and environmental class. Costs are defined per project and can be confirmed during the quotation phase.
Business case
Typical ROI for E-Crane customers ranges between 15% and 30%, depending on the application, duty cycle, energy costs, and operational efficiency gains achieved by using E-Crane technology.
