INTRODUCTIONS

DHP electric chain hoists are new type lifting equipments with the advantages of light weight, small volume high hardness, low wear and slow lifting speed, which are also small lifting equipments including the electric chain hoists and manual chain hoists. DHP electric chain hoists are either easy to carry as the chain blocks and improve the disadvantage of manual operation and low speed, which retain the convenience of hand chain hoist and electric hoist automatic function. They are also improved from chain hoists, which can avoid limited insufficient electric hoist lifting tonnage. What’s more, This types of electric chain hoists are ideal facilities for lifting, transportation, loading and unloading goods at low speed, which is enjoying high popularity in the world for saving labor and improving efficiency.

DHP electric chain hoists are newly designed on the basis of HSZ type block, which are driven by the plate braking motor and decelerated by the reducer. They adopt electromechanical integration design, replace different molds, and can suppress different specifications of wire rope which is simple and safe. DHP electric chain hoists make up the shortcomings of the bulky weight of wire rope electric hoists, which are composed of an electric motor, a transmission mechanism and a sprocket. Besides, the wire rope is changed into a chain with the biggest difference between the wire rope and the electric hoist. In addition, the lifting weight is generally 0.5 to 60 tons and the lifting height is 3~120  meters. The length of chain also can be customized, which has the purpose of completely meeting the customers’ different requirements.

DHP electric chain hoists will not be affected when the building is more than ten layers or dozens of layers, as long as it is built  with an external wall scaffold. And they are greatly used as the elevator and the electronic control box are used as the operation control center system, the construction requirements of the frame structure, the shear wall structure and the cabinet shear structure can be fully satisfied. The advantage is that the existing materials in the construction unit are used and the traditional method is used. They can be safe, reliable, easy to operate, reduce the yard, save material and improve the efficiency and so on. In all, DHP electric chain hoists are the most characteristic of a dozen or dozens of synchronized up and down, low speed and balanced speed, highly reaching the exact designated position.

DHP electric chain hoists are applicable to the hanging, climbing frame high-rise building in the outer scaffolding overall upgrade, welding storage tank with a number of crane. They are also extensively used in factories, mines, bridges, machining workshops, warehouses, terminals, storehouse, medicine and healthy service, installing equipment, engineering construction, harbours, docks and other working places for material handling, equipment installation, especially being applied in narrow working places, they are exceptionally flexible, convenient and of high efficiency. What’s more, it is very suitable for loading and unloading at low speed, engineering construction, installing equipment and mine. Besides, it is also especially appropriate for welding storage tank and high-rise building construction with a number of crane.

DHP electric chain hoists are also called DHP type low speed electric chain hoists, DHP series low speed endless chain motor lifting blocks, DHP-type hanging electric hoists, DHP durable electric chain hoists, DHP electric group hoists, electric chain hoist DHP type, DHP wireless remote control electric chain hoists, DHP series lifting endless chain electric hoists, electric chain hoists with hook DHP type, DHP electric chain hoists for construction lifting, DHP type mini electric chain hoists, DHP electric pull lifting chain hoists, lifting DHP electric chain hoists with trolley, DHP suspension electric hoists and top quality latest arrival DHP durable chain hoists.
