Installation and Facility Requirements

"The LX series European-standard electric single-girder overhead crane offers clear advantages in export projects. Take the 16 units of LX5-12 delivered to a steel plant in Indonesia in 2025 as an example — the customer required the entire machine to comply with EN 15011 and carry CE certification. We supplied a complete set of CE technical documentation (including FEA structural calculation reports and EN ISO 12100 risk assessments), and the equipment passed SGS inspection on the first attempt. This model's corrosion protection performance stood out particularly during ocean freight — the three-layer protective system of epoxy zinc-rich primer plus polyurethane topcoat (total film thickness ≥180μm) withstood 30 days of salt-spray exposure during sea transport, with zero rust found at the port upon container opening and inspection."

Streamlined Structural Design

Main girder: Fabricated with European-standard optimized box section or H-beam section, the design undergoes iterative refinement through FEM finite element analysis and field-test verification, achieving minimal self-weight while maintaining a 1.5x static load safety factor. The camber is controlled per EN 1993-6, with mid-span upward deflection at no-load set between 1/800 and 1/1000 of the span. The bottom flange features pre-machined rail mounting slots to ensure straight-line travel of the electric hoist wheels.

End carriages: Fabricated as a single welded structure from high-strength structural steel (S355JR per European standard), equipped with polyurethane bumpers and mechanical limit stops. The wheel assemblies utilize double-flanged deep-groove ball bearing wheels with tread hardness of HB300~380 and a service life exceeding 5 years. Anti-derailment plates are fitted at both ends of the end carriages to ensure the crane remains on track under extreme operating conditions.

Suspended Connection: Equipped with dedicated adjustable suspension connectors, secured to the bottom chord of the roof truss via high-strength bolts. The connectors feature adjustment bolts that allow fine-tuning of the track levelness within a range of ±20 mm, significantly minimizing the impact of plant installation tolerances on crane operation.

FAQ

Q: What is the difference between the LX European Standard and the LX European Style?

A: The core difference lies in the standard system. The LX model European Standard strictly complies with EN 13001/FEM design standards, with key components requiring CE certification, and a complete set of CE technical documentation is available for export customs clearance and EU market access. The LX model European Style follows European design principles but is manufactured to GB/T 3811 standards, targeting the domestic market. In short: European Standard is for export, European Style is for domestic sales. Krund Heavy Industry can supply both models.

Q: What are the requirements for the plant suspension points of the LX-type European standard suspension crane?

A: Answer: The suspension points must be mounted on the existing roof truss structure of the workshop, requiring no additional column support. Kelude Heavy Industry offers a free roof truss load-bearing capacity verification service (roof truss structural drawings required), ensuring a safety factor of ≥1.5 at the suspension points. Track installation accuracy requirements: straightness ≤1mm/m, joint height difference ≤0.5mm, span deviation ≤±3mm. Headroom must satisfy: lifting height + hoist mechanism height + spreader height + safety margin ≥300mm.

Q: What are the lead time and warranty period for this model?

A: Answer: Standard specifications (rated capacity ≤10t, span ≤18m) have a delivery lead time of 15–20 working days. Export projects require additional time for CE documentation preparation, and we recommend placing orders 45–60 days in advance. The complete machine comes with a 12-month warranty (extendable to 18 months per contract terms for export projects), covering free repair or replacement for non-artificial damage during the warranty period. After-sales service includes remote diagnostics plus on-site support, with a 24-hour response time domestically and a 48-hour technical support proposal for export projects.

Q: Are there additional fees for CE certification for export?

A: The LX Series European Standard models come standard with CE certification technical documentation, included in the product price at no additional cost. The documentation includes: complete machine structural calculation report (FEA finite element analysis), risk assessment report (EN ISO 12100:2010), EC Declaration of Conformity, operation and maintenance manual (multi-language versions available), and a list of CE certification documents for key components. If third-party certification body (such as SGS/TÜV) plant inspection is required, fees shall be negotiated separately.
