Маставы кран з аднабалкавым захопам LDZ: магутныя рашэнні для апрацоўкі сыпкіх матэрыялаў

LDZ single girder grab overhead crane is largely the same as the LD electric single girder overhead crane, only the захапіць вядро mechanism is different. The crane is equipped with a grab lifting trolley and is suitable for handling almost all loose and bulk materials such as garbage, industrial materials and sand. The lifting capacity of the overhead crane ranges from 2 to 10 tons and the working class is A4. This crane cannot be used in flammable, explosive or corrosive environments. It is ideal for lifting in mining, waste treatment plants, steel mills and power plants.

LDZ single beam grab bridge crane Structure

• Grab bridge cranes are composed of main parts such as bridge, grab hoisting trolley, crane operating mechanism and electrical control system.
• Bridge: This metal structure consists of main girder and end girder. The main girder adopts box structure composed of U-channel and I-beam group.
• Crane trolley: lifting goods as well as the unit running horizontally along the bridge. Two sets of electric hoists are generally installed on the trolley, one set for lifting goods up and down, and the other set for opening and closing the grapple. The electric hoist is mainly divided into two categories: wire rope hoist and hand-pulled hoist, and the former is more widely used.
• Crane running mechanism: drives the whole crane to move back and forth along the runway beam. The running mechanism adopts separate drive mode, which is completed by conical rotor with brake motor or electromagnetic brake solid rotor motor. The running speed can be 20, 30, 45 m/min.
• Electrical control system: It is the unit that provides electricity for the function of the crane. The electrical system design should consider some matters such as reliability, durability and safety precautions for lifting.

• У параўнанні з ручной працай, зварныя швы, утвораныя робатам, маюць цудоўную форму, шырыня зварнага шва раўнамерная, паверхня роўная і дэфект у асноўным роўны нулю.
• З-за раўнамернай шырыні зварнага шва пашкоджанне, выкліканае канцэнтрацыяй напружання на зварным шве, значна памяншаецца, а сярэдняя вышыня зварнага шва вышэй, чым у штучнага зварнага шва, што значна паляпшае трываласць вырабу.
