Product Description

Product Description

European standard low headroom overhead crane with electric wire rope hoist

Single girder low headroom overhead cranes are designed to aid with a range of hoisting and moving operations.
When properly designed, they will enhance daily production and provide an ideal solution for facilities and operations with limited floor and overhead space that need a light to medium duty crane.

They can be integrated into the building design, saving costs on the runway structure. The hoist trolley can go underneath the runway, providing the best end approach, and the low headroom design, especially with notched bridge beams, takes advantage of the runway depth.

Single girder bridge cranes are one of the most cost-effective lifting solutions because they are easier to install and maintain. Because they only require one bridge beam, they are more compact and lighter than a double girder crane, saving you money on materials, freight, installation, and maintenance.

Design Code:
Our Single girder standard room hoist overhead crane follows the design code of FEM, ISO EN, GB standard.
Low headroom Hoist:
C-shaped design, compact structure, smooth operation, accurate positioning, high Safety reliability, and Maintenance-friendly.
Girder:
Compact Design and low weight, use Q235B steel material welding specification follows ISO 15614, AWS D14.1, deflection can from 1/700 ~ 1/1000, MT or PT is requested for Fillet welding and UT is requested for joint welding.
End Carriage:
Direct Driving design with high transmission efficiency. Using hollow tube for the steel housing. Wheel material is alloy steel with proper heat treatment which is more stable and durable.    
Gear Motor:
Worldwide top brand gear motor to make sure the quality, IP55, F insulation class, overheat protection, manual release bar, and equipped with electro-magnetic brake.
Control Panel:
Follow IEC standard, IP55 powder coating high quality enclosure, socket plug-in for easy connection, DIN standard terminal, international brand for the inverter, MCB, Contact and electrical devices on the panel

Festoon System:
Double line Galvanized C track system with flexible flat cable, one line for hoist power and signal transmission, one line for the pendent control trolley movement. No-welding claw is design for the brackets of the festoon system fixing.
Safety Protection Functions:
Demarco single girder overhead crane include a lot of protection functions, like Overheat protection for the lifting, load cell type overload limit switch, up&down position limit switch, cross limit switch for the cross travel and long travel. Phase sequence relay, and other optional functions, like crane monitoring system, LED load displayer.
Controls:
Demarco single girder overhead crane can offer both options of remote control and pendent control
Anti-corrosive Treatment:
Shoot Blasting follow ISO8501-1 SA2.5 class, roughness follow ISO 8503 G class, clearness follow 8502-3 Level II. Use top brand's Rich zinc epoxy painting for the prime, middle layer coating. Use polyurethane topcoat for the finished layer coating. All DEMARCO painters are trained or inspected by NACE or FROSIO level II Inspector

New types of Cranes

Based on bringing in and assimilating foreign advanced technology, this type of crane takes modular design theories as guidance, uses modern computer technology as means, introduces optimized and reliable design methods, which is new type of crane made by employing import configuration, new material and technology and has features in light-weight, generalizing, energy-conservation and environmental protection, maintenance free and high technology content.
Design, production and inspection carry out the last issued relevant national standard, equivalently dopts some foreign criteria including FEM, DIN and IEC. Compared with the general QD bridge crane, its weight is reduced by about 15~ 30%, the maximum wheel pressure is reduced by about 10~ 35%, which can the requirements of crane for factory building structure and reduce production cost. As the core component of driving mechanism, reducer gear pair with hard tooth surface and high accuracy, together with steel reel, forged wheel and variable-frequency speed regulating system, which makes this type of crane become renewal product of traditional general bridge crane and applied in industry of machinery production, assembling, petrochemicals, warehouse logistics, electric power construction, papermaking and railways.
