Single girder grab crane

Henan Mine Crane LDZ type electric single girder grab crane is based on the standard electric single girder crane designed to improve the design of special lifting equipment for bulk materials, the core hoisting mechanism for the customized electric hoist, pickup device carrying a special grab, with vertical lift, longitudinal and lateral three-dimensional movement, can be used in general industrial operating environment to achieve sand and gravel, coal, ore, grain and other types of bulk materials intermittent, repetitive loading and unloading and handling.

Can be realized in the general industrial operating environment of gravel, coal, ore, grain and other types of bulk materials, intermittent, repetitive loading and unloading and handling, is the preferred equipment for overseas bulk material handling scenarios, but also Henan Mine Crane in the field of bulk material lifting core products.

1. Core structure design

LDZ type electric single girder grab crane with electric single girder crane main girder, end girder as the basic framework, the core consists of three key parts, the structure of the synergistic cooperation to protect the stability and efficiency of bulk material lifting:

1.1 Main bearing structure: the use of high-quality steel welding molding of the single main girder and end beams, compact structure and light weight, low requirements for plant load-bearing, track foundation, no need for overseas small and medium-sized plant to do additional structural reinforcement, adaptability is very strong;

1.2 Lifting mechanism: equipped with customized dual electric hoist lifting mechanism, providing stable power for the grapple, different from the single rope drive of single hoist, dual hoist with four rope grabs, completely avoiding the problem of tilting of grabs and leakage of bulk materials;

1.3 Fetching device: four-rope special grapple is equipped as standard, with flexible opening and closing of the grapple, uniform gripping strength, which can be adapted to the lifting of bulk materials of different grain sizes, and at the same time, the grapple is easy to dismantle and replaceable, and the specification of the grapple can be customized according to the type of bulk materials.

2. Core Product Advantages

As a double hoist four-rope grab single girder crane specially designed for bulk material lifting, its core advantages are centered on stability and efficiency, high reliability, low cost and easy maintenance, which perfectly fit the pain points of overseas customers’ operation and procurement, and are also its core highlights distinguishing it from grab double girder cranes and ordinary single girder cranes:

2.1 Dual hoist + four-rope grab, stable and more efficient operation:

the core configuration of dual hoist lifting mechanism with four-rope grab, balanced power output, grab opening and closing and lifting process is smooth and tilt-free, effectively avoiding leakage problems in the process of bulk material lifting, and the efficiency of grasping and unloading is more than 30% higher than that of the traditional single-rope grab, which meets the intermittent and high-frequency operation needs of overseas bulk material scenarios;

2.2 High-quality components, equipment reliability
the core components of the whole machine are selected from high-end quality models, forged wheels with strong load bearing and wear resistance, Nanjing special drive system runs smoothly and has low failure rate, and all the accessories have gone through strict fatigue testing and quality inspection, so that the stability of the equipment operation is far more than the industry average under the common environment of overseas high temperature, high dust and other bulk material operation, which significantly reduces unplanned downtime. The unplanned downtime is greatly reduced;

2.3 Low procurement costs, cost-effective overall use

as a single girder grab crane, its procurement costs are reduced by more than 40% compared with grab double girder cranes, while the equipment is lightweight, low operating energy consumption, significant savings in electricity costs, suitable for overseas small and medium-sized bulk material enterprises cost control needs, is a cost-effective alternative to bulk material lifting scenarios;

2.4 Simple structure and easy maintenance, suitable for overseas maintenance environment

the whole machine continues the simple structure of electric single girder crane, no complex precision parts, simple maintenance process, and wearing parts are international standardized specifications, replacement without special tools, ordinary workers can complete daily maintenance after simple training, completely solve the pain point of the lack of professional maintenance personnel of overseas customers.

3. Adaptation Scenarios and Overseas Adaptability

3.1 Core adaptable scenes

This bulk material lifting grab single girder crane is widely used in overseas bulk material handling scenes, including gravel quarries, coal warehouses, grain warehouses, ore processing plants, building materials factories, small ports / wharves, etc., and can be responsible for loading and unloading of all kinds of bulk materials, transfer, stacking, etc., and it is suitable for all kinds of bulk material lifting of particle size 0.5mm-500mm;

3.2 Adaptation to overseas standards

the product complies with China’s national crane industry standards, the core accessories are compatible with international common specifications, and can be adapted to the needs of overseas customers to meet the operational specifications of different countries, and can be put into use without additional modifications;

3.3 Power supply customization

power supply parameters support customization (220V-660V/50Hz/60Hz), can be perfectly adapted to North America, Europe, Southeast Asia, the Middle East and other overseas regions of the power grid requirements, to completely solve the problem of power supply incompatibility;

3.4 Environment-adapted design

the surface of the whole machine is professionally treated with anti-rust, anti-corrosion and anti-dust treatment, which can be adapted to the harsh environments commonly found in bulk material operations such as high dust, high humidity, coastal salt spray, etc. overseas, and greatly enhance the service life of the equipment.

4. Overseas exclusive supporting services

Henan Mine Crane, as a professional grab crane manufacturer, for overseas customers to provide a full range of ancillary services, completely eliminating overseas procurement concerns, so that customers can buy with confidence, with peace of mind: 4.1 Data support: to provide a full set of technical data in English, including installation drawings, operation manuals, maintenance manuals, spare parts manuals, all materials are labeled in English and Chinese bilingual, easy for overseas customers to access and use;
