The explosion-proof mark of the explosion-proof electric single beam suspension crane is ExdeibIICT4/DIP A21 TA, T4, which can be used in explosion-proof levels IIB, IIC, and dust environments. It is widely used in factories, warehouses, material yards, and other places in military, chemical, coal washing plants, pharmaceutical units, and can work in flammable, explosive, and corrosive media environments.This product is operated on the ground and is used in conjunction with HB (BCD) and HBS (BMD) explosion-proof electric hoists. It has a working level of A3-A5 and a working environment of -25~40 ℃. It has the characteristics of reasonable structure, beautiful appearance, and strong explosion-proof performance.

The LDY electric single beam crane (for lifting molten metal) is a product developed in accordance with the relevant provisions of the Notice on Relevant Opinions on the Rectification of Metallurgical Cranes issued by the Quality Inspection Office [2007] No. 375, the Notice on Relevant Issues Concerning the Special Rectification of Pressure Pipeline Components and Cranes issued by the Quality Inspection Office [2008] No. 347, and the TSGQ0002-2008 Safety Technical Supervision Regulations for Cranes - Bridge Cranes. It is a special single beam crane specifically designed for lifting molten metal in the metallurgical industry.LDY electric single beam crane (for lifting molten metal) (hereinafter referred to as crane) is a bridge type crane installed on an elevated track and running above the track. It is a crane used for lifting molten metal using a metallurgical electric hoist as the lifting mechanism. The rated lifting capacity is not more than 10t, and the working level of the electric hoist is not less than M6. It is a lifting equipment that allows the molten metal package hanging on the crane hook to achieve vertical lifting and horizontal movement in space.Its retrieval device is a hook.

The LDP type electric single beam crane belongs to the ultra-low clearance light and small crane. The electric hoist is located on one side of the main beam, which increases the service space of the hook and can reduce the height and cost of the factory building. This product is widely used in work environments ranging from -25 ℃ to 40 ℃, with low workshop clearance height, due to its advantages such as large wheelbase, smooth operation, compact structure, good rigidity, sensitive operation, low noise, comparable appearance, and beautiful appearance.The LDP electric single beam crane is a lightweight lifting equipment designed and manufactured in accordance with GB/T3811-2008 and JB/T1306-2008 standards, and is used in conjunction with CD1 and MD1 electric hoists. Its rated load is 3t~10t, with a span of 7.5m~22.5m, a working level of A4, and a lifting height of 6-12m. The main operating methods are ground operation (ground operation, remote control operation, ground+remote operation). If the span and lifting height exceed the range listed in the sample, we can also conduct non-standard design according to user needs.

The LDE electric single beam crane is designed and manufactured according to JB/T306-1994, using an electric hoist as the lifting mechanism. The entire machine runs on two tracks. The single beam bridge crane has compact dimensions, low static height of the building, light self weight, and small wheel pressure. Widely used in industrial and mining enterprises, warehouses, mechanical processing workshops, metallurgical plant auxiliary workshops, material yards, power stations, etc. for transportation, assembly, maintenance, and loading and unloading operations, it can also replace ordinary double beam bridge cranes and be used in production workshops in the light textile industry and instrument industry. His work level is light and intermediate.The product is a type of crane developed in recent years based on the LDA electric single beam crane according to the needs of the market and users.Compared with the ordinary LDA electric single beam crane, this type of product has two independent operating electric hoists. These two electric hoists can independently complete the lifting work of the workpiece and cooperate with each other to complete the flipping of the large workpiece. At the same time, each operating handle can independently control the shared crane operating mechanism, and the price is only slightly increased compared to the ordinary LDA electric single beam crane. Therefore, it is an economical new type of lifting machinery.The commonly used lifting capacity is 1-25t, with a span of 7.5m-22.5m, using a three-phase 380V, 50Hz power supply, and working environment temperature of -25 ℃ -40 ℃. It can also be designed separately according to user requirements. 

The LDA electric single beam crane is an improved design based on the LD model, which has the characteristics of reasonable structure and strong overall rigidity compared to the LD model. The whole machine is used in conjunction with CD1 and MD1 electric hoists, and is a light and small lifting machinery. Its lifting capacity ranges from 1T to 10T. The span is 7.5-22.5m, the working level is A3-A5, and the working environment temperature is -25 ℃~40 ℃.This product is widely used for lifting goods in different occasions such as factories, warehouses, and material yards. It is prohibited to use it in flammable, explosive, and corrosive media environments. This product has two operating forms: ground and control room, with open and closed control rooms available. According to the actual situation, it can be divided into two types of installation: left or right side installation, and two types of installation: right side and end face in the direction of entry. To meet the diverse needs of customers in making choices. All lubrication devices for manual single beam cranes. Inject lubricating oil (dry oil) every six months.
