LHX Type European Standard Electric Hoist Double-Girder Crane

The LHX European Standard Electric Hoist Double-Girder Bridge Crane is a high-performance double girder overhead crane designed and manufactured by Kelude Heavy Industry in accordance with FEM/DIN European standards. The crane features a lightweight box-type main girder design, paired with a European standard two-speed/full variable-frequency drive electric hoist (FEM 2m~4m work duty). With a lifting capacity range of 5~80t and spans from 10.5~31.5m, both the crane bridge and trolley travel come standard with inverter drive. Compared to conventional QD Type double-girder cranes, the dead weight is reduced by 20~35%, resulting in lower wheel loads and significantly reduced factory building foundation costs. This series is widely used for heavy-duty material handling in industries such as machinery manufacturing, steel & metallurgy, automotive assembly, and warehousing & logistics.

Q: How do I choose between the LHX and the QD Type double-girder crane?

A: The core decision should be based on Total Cost of Ownership (TCO), not just the purchase price: ① The LHX typically costs 10–20% more upfront than the QD, but its lighter dead weight reduces steel structure requirements for the factory building, saving over 30% on civil construction costs — making the LHX more cost-effective overall for new facilities; ② The LHX's full variable-frequency drive saves 25–40% energy compared to the QD's resistance-based speed control. For a 20t double-girder crane running 6 hours a day, this translates to annual electricity savings of approximately ¥12,000–20,000; ③ For export projects — the LHX is designed to FEM/DIN standards, eliminating the need for secondary modification and re-certification. In short: choose the LHX for new high-standard facilities or export projects; choose the QD for retrofitting existing plants where budget is a primary concern.

Q: Is there a significant reliability gap between European standard electric hoists and domestic hoists?

A: The European standard electric hoist (FEM 2m–4m) standard on the LHX differs fundamentally from domestic CD/MD Type hoists in three key indicators: ① Gear life — European hoists use carburized and quenched hardened tooth flank gears (HRC58–62) with a design life of ≥10,000 hours, while domestic hoists typically use quenched and tempered soft tooth flank gears (HB220–280) lasting approximately 3,000–5,000 hours under equivalent conditions; ② Brake — The European standard disc brake delivers braking torque ≥1.5× rated torque, whereas domestic conical rotor brakes rely on motor axial force, which degrades noticeably under sustained heavy loads; ③ Duty Cycle — European hoists are designed for 60% ED (suited to frequent start-stop operation), while domestic units are typically rated at 25–40% ED. For workshops operating at Work Duty A5 and Above, the European standard hoist is recommended.

Q: Can the LHX be operated from a cab?

A: Yes. The LHX comes standard with dual-mode operation via a floor pendant and wireless remote control, but cab operation is available as a custom option. Cab choices include: ① Fixed Operator Cabin — mounted beneath one end of the main girder, suitable for single-station fixed operations; ② Mobile Operator Cabin — travels with the trolley for better visibility, ideal for large-span, multi-point operations. The cab comes standard with air conditioning/heating, ergonomic seating, and a Joystick Console (Master switch + Touch Screen (HMI)). For metallurgy workshops with high-temperature, dusty, or hazardous atmospheres, a pressurized explosion-proof cab can also be specified.

Q: What is the Lead Time and installation service?

A: Standard models have a Lead Time of 25–35 days (including design, manufacturing, and in-house testing); non-standard customization adds 10–20 days. Kelude Heavy Industry provides: ① Free design proposal — including factory building load analysis, Foundation drawing, and power supply capacity calculation; ② Nationwide Installation & Commissioning — professional installation teams with Certified Operation, covering crane rail installation, electrical wiring, PLC commissioning, and load testing; ③ One-year Full Machine Warranty plus a two-year warranty on key components (hoist, Reducer/Gearbox, Frequency Inverter/VFD); ④ Lifetime technical support with 24-hour after-sales response. The LHX series has delivered over 500 units cumulatively across domestic markets and Southeast Asia, the Middle East, Africa, and other regions.
