Electric Hoist For Double Girder Crane
Overview
Crane trolley and crane has the features of lightweight, modular design, concept and advanced manufacturing process, compact structure, smooth operation, high lifting height, and energy saving. So it greatly reduce the user's crane construction costs and crane operating costs, and improve the crane's overall quality and performance.
Advantage:
1. Three-in-One structure, Stable and reliable operation, small volume
2. High efficient electric motor with hard tooth surface reducer, to achieve the low energy consumption and large output torque
3. The electromagnetic brake can adjust itself automatically with high precision, to achieve fast and reliable braking with low noise.
4. The steel wire rope with high strength and high flexibility, to achieve greater and safer lifting.
5. High strength nylon rope guide and pulley, its self-lubricating help to achieve a longer service life of the steel wire rope
6. High strength alloy wheel assembly achieves a long service life for the wheels.
7. Modular design to realize the flexible combination url:http://www.fwcranes.com
Description Double girder overhead crane is composed of box type bridge frame, lifting trolley, crane traveling mechanism, and electrical system. It is rely on the bridge frame along the workshop orbital direction moving longitudinal, the trolley along the main beam direction moving transverse and the hook lifting movement to work. It could be classified into several working duties, e.g. A5, A6, A7 according to the working frequency and pure working time. Double girder overhead crane allocation hook used in machining, assembly workshop, metal workshop, metallurgy and casting workshop and warehouse handling work; allocation of grab is suitable for metallurgy, cement, chemical or open fixed span in bulk material handling. Features Reasonable structure and favorable performance. Smooth starting and stopping. Safe and reliable traveling, long life. Low noise, commodious cabin with good view. High quality automatic welding and NDT inspection. Crane drive: IP54 or IP44, level F insulation. Designed according to your required.
Item Specification Capacity T 0.25~32 or as required Lifting height m 3~30 or as required Lifting speed m/min 0.35/3.5, 0.7/7, 7, 0.8/8, 8 or as required Travelling speed m/min 20/30 or as required Wire rope type 6x37+1 Dia. 3.6/4.7/7.7/11/13/15.5/17.5/22.5/25.5 Working system FC=25%(Intermediate) Power source 380V50Hz, 3-phase AC or as required
Description of product as follows: 1. Lifting electric motor cover It made of high strength and light aluminum alloy but hard and fit for the use in the terrible work environment with a high heat dissipation rate and all tightness design. 2. Inverse phase sequence protecting device: It is the special electrical installation, which control the circuit not to work in case of wiring error in the power supply. 3. Limit switch: The limit switch device is installed where the weight is lifted on and off to make the motor to stop automatically so as to prohibit the chains from exceeding for safety. 4. 24V/36V device: It is used to prohibit the emergencies from occurring in case of the leakage in the switch. 5. Side magnetic braking device: This device shall realize the instant brake in case of the power dump. 6. Chain bag: It shall be light, handsome and durable. 7. Chain: The chain shall be adopted the imported FEC80 ultra heat-treatable steel alloy. 8. ISO: M5/FEM: 2AM, insulation grade: F, protection class(hoist and push button):IP65 9. Special features: It is typical of unique optimal structure in shortening the distance between the machine body and the beam tracks, applicable to operations in side fairy low buildings, especially suitable for use in temporarily erected plant buildings or on the sites where expansion of effective hoisting spaces inside the buildings is required The product attribute Lifting Speed 4.4m/min Limit Switch yes Phases 3 Rotation speed 1400r/min Frequency 50hz/s Voltage 200v-600v Power 3Kw

Gear:they are innovated symmetrical arrayed highspeed synchronous gears,and are made from international standard gear steel. Compared with common gears,they are more wearable and steadier,and more laborsaving. Chain:adopts high strong chain and high precision welding technology,meet ISO3077-1984 international standard;fits for gusty overload work conditions;takes your hands a better feeling;multi-angle operation(with 45¡ã). Hook:made of high-class alloy steel,it has high strength and high security;by using newy desing,weight will never escape. Limit Switch:using limit switch component in designation to protect chain and ensure security. Components:main components are all made of high-class alloy steel,with high precision and security. Framework:slight design and more beautiful;with less weight and smaller work area. Plastic Plating:by adopting advanced plastic plating technology inside and outside,it lookslike a new one after years of operation. Encloser:made of high-classed steel,more firmly and dexterous.
