Single Girder Semi-Gantry Crane

Henan Mine Crane electric hoist semi-portal cranes use European electric hoist as the hoisting mechanism, using a single outrigger + the other side of the plant rail semi-portal structure operation, can complete the vertical lifting of the material, longitudinal and lateral movement, the fetch device to support hooks, grabs, electromagnetic suction cups a variety of configurations, the outrigger can be cantilevered to expand the scope of operation, Henan Mine Crane is the integration of frequency conversion speed control, energy saving and lightweight, high-strength transmission Technology to create a new generation of semi-portal lifting explosive products.

This new electric hoist semi-portal crane for the workshop single side of the track, site constraints scene to do a comprehensive upgrade, support for the driver’s room, handle, wireless remote control, PLC linkage multi-mode operation. Lightweight design of the whole machine, self-weight compared with traditional models to reduce 15%-30%, the maximum wheel pressure reduced by 20%-35%, energy consumption reduced by 10%-20%, is a small site, low-cost material handling, the first choice of upgraded models of semi-portal lifting equipment.

1. Product core positioning and design standards

Core positioning of electric hoist semi-portal cranes: to provide frequency conversion and energy saving, lightweight, high transmission efficiency semi-portal lifting solutions for global single-side track, site constraints.

2. Core structure and functional design

1. Frequency conversion speed control and energy saving system: the hoisting and running mechanism adopts frequency conversion speed control, with a speed range of 1:10, realizing slow speed for heavy load and fast speed for light load, smooth and shockless operation, low noise, energy consumption is reduced by 10%-20% compared with the traditional model, which has an outstanding effect of energy saving and consumption reduction.
2. High-strength hardened gear reducer: the reducer adopts tooth hardness ≥ 60HRC hardened gear + integrated case design, transmission efficiency of more than 95%, the service life is 2-3 times longer than the traditional soft gear reducer, more stable transmission, less wear.
3. Three-in-one direct-connected drive mechanism: large and small car operation adopts three-in-one direct-connected drive, integrated motor, reducer, brake, high transmission efficiency, compact structure, no intermediate transmission loss, equipment failure rate is greatly reduced.
4. Lightweight and high-strength structure: lightweight optimization of the machine design, self-weight reduction of 15%-30% compared with traditional cranes, the maximum wheel pressure reduction of 20%-35%, the ground and plant track load-bearing requirements are lower, suitable for the transformation of the old workshop.
5. Multi-mode intelligent control: support the driver’s room operation, handle control, wireless remote control, PLC linkage control four modes, which can meet the different needs of a single person close control, multi-person cooperation, remote automation operations.
6. Multi-purpose pick-up device: flexible selection of hooks, grabs, electromagnetic suction cups, hooks for lifting miscellaneous goods, grabs for loading and unloading bulk materials, electromagnetic suction cups for handling steel, a machine to adapt to the whole range of conventional material operations.
7. Flexible cantilever configuration: the outboard side of the outrigger can be configured with cantilever structure, realizing trans-inside to trans-external operation and expanding the handling range; the cantilever can also be canceled, adapting to a narrower working space, with stronger adaptability to the site.

3. Core product advantages

1. Smoother frequency conversion speed control: 1:10 wide range frequency conversion speed control, heavy load stable, light load fast, no impact shaking, protect materials and equipment, operation safety greatly improved.
2. Transmission efficiency and long life: hardened gear reducer + three-in-one drive, transmission efficiency of more than 95%, the core components to extend the life of 2-3 times, long-term use of the failure rate is extremely low.
3. Lightweight and cost-effective: light weight and low wheel pressure reduce the cost of track laying and workshop infrastructure, reduce energy consumption by 10%-20%, and save a lot of electricity cost in long-term use.
4. Wide adaptability of multiple control modes: four control modes can be selected, adapting to different operation modes such as manual operation and automated workshop, with a high degree of flexibility.
5. Strong adaptability to half-door site: single-side outrigger design, no need for double-side ground track, perfectly adapted to the workshop one side of the existing track, the site is narrow and special working conditions.
6. Global adaptability and easy to export: support international certification, global power grid customization, European upgrade design compatible with global habits, can be directly exported around the world.
   

4. Global Adaptation and Application Scenarios

• Application Scenario: Global machining workshop, logistics and storage park, building materials processing plant, small freight yard, steel market and other one-side track restricted scenarios, used for loading, unloading, handling and shifting of conventional materials such as steel, components, packing boxes, bulk materials, finished equipment and so on.
• Standard adaptation: support CE, ISO9000, GOST, FEM and other international certifications, power supply 220V-660V/50-60Hz is fully customized, adapted to global power grid standards.
