Product Feature And Application
Core Advantages & Design Highlights
Space-Efficient & Lightweight Structure
The compact single girder overhead crane design boasts a lightweight build and minimized wheel loads. Its low headroom requirement makes it an optimal workshop lifting equipment for standard factory buildings.It rarely demands structural reinforcement of the existing building, keeping retrofitting and installation expenses to a minimum.
User-Friendly Operation
This top running bridge crane supports both ground-based pendant control and wireless radio remote control. The intuitive operating system ensures that operators can quickly master the handling of medium to light-duty loads.
Cost-Effective Upkeep
All critical components are highly standardized, and consumable spare parts feature excellent interchangeability. Routine maintenance requires only basic lubrication and periodic fastener tightening. This economical maintenance profile makes the LD type crane significantly cheaper to run over its lifecycle compared to double-girder systems.
Comprehensive Safety Features
To guarantee maximum workplace safety, the crane comes standard with robust protection systems, including lifting height limiters, cross-travel and long-travel limit switches, overload protection devices, and safety latches on the lifting hooks.
Primary Application Scenarios
Manufacturing & Assembly Lines: Perfect for lifting machine parts, assisting with equipment assembly, and transferring molds in general fabrication shops.
Logistics & Storage Centers: Ideal for loading, unloading, stacking, and moving raw materials and finished goods in warehouse environments.
Repair & Maintenance Facilities: Acts as a reliable auxiliary lifting tool for disassembling heavy machinery, performing overhaul work, and replacing industrial components.
Light Industry, Electronics & Building Materials: Frequently applied in production line material handling and offline product handling, meeting the requirements of light-to-medium capacity lifting tasks.
Production details
Main Girder (Single Beam)
Typically features a welded box-girder construction fabricated from U-channel steel and I-beams. The standard material is Q235B carbon steel. For applications involving larger spans or heavier lifting capacities, Q345B low-alloy high-strength steel is utilized to ensure optimal structural rigidity.
End Carriages (End Trucks)
Constructed with a box-type structure made of high-strength rectangular steel tubes or welded U-shaped steel plates. It is equipped with rubber buffers and travel limit switches to effectively prevent derailment and accidental collisions.
Crane Wheels (Travel Wheels)
Manufactured from ZG35CrMo cast steel or 45# forged steel. The wheel treads undergo induction quenching, delivering exceptional surface hardness and outstanding abrasion resistance.
Hoisting Mechanism (Electric Hoist)
Equipped with either the CD1 type electric hoist (single-speed lifting) or the MD1 type electric hoist (dual-speed lifting) to meet different precision requirements for lifting operations.
Certification
All our products are strictly tested and certified to meet international standards
FAQ
Q: What information is required to get an accurate quotation for an LD type single girder bridge crane?
A: It is recommended to provide the following core parameters:
1.Rated lifting capacity
2.Workshop span (center-to-center distance of the crane rails)
3.Required lifting height
4.Control mode (pendant control / wireless remote control)
5.Working scenario and operation frequency The more complete the information, the more accurately the quotation and solution will match your needs.
Q: Can the lifting capacity, span length and lifting height of the single girder crane be customized according to actual workshop conditions?
A: Yes. Standard tonnages and spans cover most conventional scenarios. For workshops with special dimensions or special lifting height requirements, you can provide workshop drawings and working condition details. Our factory will provide non-standard customized solutions, and all parameters comply with crane design specifications and industry standards.
Q: What is the warranty policy for the single girder bridge crane?
A: We provide a 12-month warranty for the whole machine, starting from the date of installation, commissioning and acceptance. Wear parts (such as wire ropes, brake pads, push buttons, etc.) are covered by a 3-month warranty. During the warranty period, parts damaged by non-human factors will be replaced free of charge. We also offer lifelong technical support and spare parts supply.
Q: Can the crane be adapted to local power supply standards?
A: We support customization of global mainstream power parameters, including voltages of 220V, 415V, 440V, 460V, etc., and frequencies of 50Hz/60Hz, to match the grid standards of different countries and regions. We can also provide export certification documents such as CE certification.
Q: What is the delivery lead time for an LD type single girder crane?
A: The production cycle for standard configuration models is 15–20 working days; for non-standard customized models, it is 25–30 working days. The exact delivery time will be confirmed based on order quantity, customization requirements and the factory's production schedule.
