Brief Introduction of LH Electric Hoist Double Girder Overhead Crane

The electric hoist double girder overhead crane is a kind of lifting equipment, and it is a kind of machinery that performs cyclic and intermittent movements. A working cycle includes: the pick-up device lifts the item, then moves horizontally to the designated place to lower the item, and then performs a reverse movement to return the pick-up device to its original position for the next cycle.

LH model double girder overhead crane with hoist trolley consists of box type main girder, end carriages, lifting trolley, long crane traveling system and electrical system. It employs fixed electric wire rope hoist, which is fitted on trolley frame as the hoisting mechanism. LH model double girder overhead crane can make full use of the space below the bridge to lift materials. It has the advantages of compact size, low building clearance height, light self-weight, small wheel pressure, etc.

Advantages of Electric Hoist Double Girder Overhead Crane

  • Compact size, light weight, low energy consumption.
    The whole crane adopts modular design, and the structure from hoist, end beam to main beam is more reasonable, which makes the crane's dead weight much lighter than traditional cranes. The track wheel pressure is small, less requirements are placed on the factory building, the application range is wide, and the cost of the factory building is saved.
  • Low building clearance height, small space occupation.
    The low headroom design enables very efficient use of plant space. It is more friendly to the layout planning of the available working space of the existing factory. New factories can be planned even smaller.
  • High operating efficiency.
    The frequency conversion technology is used to make the loading positioning faster and more accurate while maintaining the stable operation of the crane, which greatly reduces the shaking of the loading. It also reduces mechanical forces between the crane and the plant structure.


Technical Specifications of LH Electric Hoist Overhead Crane

The capacity is from 5 tons to 32 tons. The span is 7.5~31.5m. The lifting height is 6~30 meters. It has two kinds of classification, that is, light and medium. We also design and manufacture the nonstandard crane according to user’s requirements. The working temperature is generally -20°C to 40°C.It is forbidden to work in environment with combustible, explosive or corrosive media.
This product has three control modes: ground operation, remote control operation and cab operation, which depends on the different user's requirements.

Components of LH Electric Hoist Overhead Crane

Bridge (Crane span structure), Crane traveling mechanism, Electric hoist trolley (equipped with lifting mechanism and cross traveling mechanism), electrical and other components.

  • Bridge includes Main beam, End carriages, trolley running track, handrail, walking platform, etc.
    Main beam: It is the basic component of the whole crane, bearing all kinds of loads, with sufficient rigidity and strength. (Strength is the ability to resist fracture and rigidity is the ability to resist deformation.)
    Main beam material is Q235B. Q345B can also be selected upon client’s request.
    Its structure is box girder type. This design has many advantages, such as large overall rigidity, good manufacturing, assembly, transportation and maintenance conditions.
    The main beam is generally made into a uniform upward arch shape to reduce the trolley hoist climbing and sliding, and enhance the bearing capacity of the main beam.
  • Crane traveling mechanism includes wheel, motor, reducer, brake, etc.
    It is to provide driving force for the driving wheel, so that the whole crane can move front and back along the fixed track.
  • Electric hoist trolley
    It is installed on the bridge and consists of lifting mechanism,trolley running mechanism and lifting trolley frame, which can move left, right, up and down.
    When the lifting capacity is more than 10t, there can be main and auxiliary hooks.
    The trolley can be equipped with Fixed CD hoist (Single lifting speed), MD hoist (double lifting speed) and variable speed (Frequency converter) according to the speed requirements from customers.
  • Electrical parts: Electric control box (Chint or Schneider Brand), Frequency converter (Optional), Power system with Trolley power supply cable, Crane traveling power line (Slip wire such as mono pole slide, Seamless type bus bar, collector)
  • Protection equipment includes Phase protection system; Anti-collision system; Overload protection system; No-voltage protection system; Over-current protection system; Lifting limit protection system; Traveling limit protection system; Ground protection system; Emergency stop protection system; buffer system, which can ensure safe operation of crane.
  • Control method: Pendant control, remote control or cab control.

Application of Electric Hoist Double Girder Overhead Crane

Double Girder Overhead Crane is erected on the track of fixed span pillars of buildings. It is widely used in workshops and warehouses, such as machining workshop, product storage and dispatch warehouse, goods yard, power station, plastic injection molds changing, finished steel product industries. It is applicable to the transfer, assembly, maintenance and repair as well as loading and unloading indoors or in open air.

Our LH double girder overhead cranes have been exported to many countries and regions, such as Maldives, Oman, Uzbekistan, Tajikistan, Philippines, Pakistan, Cambodia, Kenya, Ethiopia, Algeria, Honduras etc. We provide professional design scheme according to customer's working condition, help them to solve the problems of height limit and steel structure. We received good comments and repeated orders from them.

 
 


Why Custom a Crane Solution?

At Yuantai, we know that there is no "one size fits all" in the lifting field. Universal cranes are suitable for general occasions, such as factories, warehouses, etc.

European overhead cranes are further upgraded in technology and are suitable for working conditions that need smaller crane structures, high positioning accuracy, and low noise.

Besides, different applications have different needs for cranes. So, we provide customized cranes according to the special needs of our customers. For example, steel and machinery industries often lift billets, steel plates, and other magnetic items, so need electromagnetic overhead cranes. Ports and docks often need to load ore, gravel, and other bulk goods, so need grab bucket cranes. Chemical and other dangerous places often need to carry flammable and explosive materials, so need explosion proof cranes. In short, you need to choose a suitable crane according to your actual situation.

  • Double Girder Cranes:
    Double girder overhead cranes are designed for heavy-duty loads. And double girder eot cranes can be customized to meet specific needs, including load capacity, span, and lift height.
  • Single Girder Cranes:
    Single girder cranes are designed for lighter lifting applications.
  • Top Running Cranes:
    Top running cranes are designed to travel along the top of the building.
  • Underslung Cranes:
    Under running cranes are designed to travel along the bottom flange of the crane runway.
