Second, our problems of electric wire rope hoist crane manufacturers in the domestic impact of foreign advanced products also have to take the road of technological lever hoist innovation , has made substantial progress in electric hoist control technology , but compared with foreign hoist control technology there is a large technological gap . CDl -type wire rope hoist can be widely used in the domestic market for nearly 40 years, its success , but in terms of its use of the process has also exposed some problems to improve deficiencies. Now the following main aspects: ( a ) fewer varieties , specifications missing our CDl electric hoist lifting capacity , only 0.5t, 1t, 2t, 3t, 5t, 10t6 species coverage lifting height of 6 -30m, lifting speed :1-5t single speed lever hoist as 8m/min, double speed as 8/0.8m/mini; 10t single speed 7m/min, double speed as 7/0.7m/min. While some domestic manufacturers on the basis of the development of the 10t 16t, 20t, expanding the range of large-tonnage electric hoist , but still can not form a more complete and reasonable wire rope hoist products , and abroad in the weight range from 0.25-80t and multi- kinds of lifting height and lifting speed combination compared to a big gap there .

Lifting personnel and equipment , the decentralization of large machinery equipment and materials . It is the underground mine production systems and ground- coupled industrial square hub is mine transport throat. Therefore , mine hoisting equipment occupies an extremely important position in the whole process of mine production , with the development of science and technology and production wire rope hoist mechanization and centralization , at present, the world economy is relatively developed countries . Running speed hoist has reached 20 ~ 25m / s, a promotion reached 50t, motor capacity exceeding Pat 10000kw, especially its safety and reliability . In the mine production process, if a fault lifting equipment , will inevitably result in production. Light , affecting coal production ; severe, it will endanger personal safety. In addition, mine hoisting equipment is a large comprehensive machinery - Electrical equipment , its cost and power consumption is relatively high , so the design in the design and reconstruction of new mines and old mines , determining a reasonable upgrade system, you must go through many the technical and economic comparison , combined with the specific conditions of the mine to ensure that lifting equipment in the selection wire rope hoist suppliers and operation of two aspects are reasonable , which requires economical mine hoisting equipment                                     View Details

The technical features of the domestic electric explosion-proof forklift: 1, communication control system with constant torque at low speed and high speed constant power control, make it has good dynamic performance, and has the function of energy recovery, ramp fall prevention, reduction, etc. 2, ac motor in structure does not use the contact and the carbon brush, so there's no need to clean up and replace carbon brush is free of maintenance, which makes the explosion-proof security improved. 3, by explosion-proof ac motor in two temperature sensing and control system of control, make the explosion-proof forklift heat up and heat drop two control operation condition, can not only improve the ability of explosion protection forklift truck temperature control, and greatly to ensure normal operation of the machine. 4, adopts hydraulic wet braking in brake form, avoids the production of brake spark and high temperature, explosion-proof performance of the engine. The above technical characteristics with high transmission efficiency, small current, low temperature, electrical maintenance free and braking performance is good, no spark, low rise, improve the performance of the whole machine, and relatively guarantee in explosion-proof environment for a long time on the machine work. To sum up, the development of domestic electric explosion-proof forklift has experienced three stages, and three stages of technology development are made by electric lift trucks in the technology development and the development of explosion protection technology, combining the present domestic electric explosion-proof forklift technology basically is still in the second stage, to enter the third stage of technical electric explosion-proof forklift manufacturer only caly, zhejiang science and technology co., LTD. In recent years, newly developed single motor explosion-proof ac hydraulic electric forklift and double motors explosion-proof ac electric forklift control system for hydraulic brake, not only created a domestic electric explosion-proof forklift way of independent research and development with independent intellectual property rights, and to fill the domestic no explosion-proof ac control technology of electric lift trucks in the blank.

My company in the fierce market competition continues to high-quality product quality, good lever hoist after-sales service. Bring rest assured quality products for the country lifting industry. For many years to high-quality product quality, good after-sales service management system, and well received by the masses of users. 1. When lifting heavy objects, it is strictly prohibited to workers to do any work or walk under the weight, so as to avoid personal accident. 2. In the process of lifting, regardless of the weight increase or decrease, drag hand chain, uniform force should be gentle, don't too hard, so as to avoid hand chain beating or snap ring. 3. The operator when hand pull is greater than the normal force is found, should immediately stop using it. To prevent the hand chain wear.                                     View Details
