MB型半門式起重機(jī)

MB型半門式起重機(jī)依據(jù)GB/T14406-2011標(biāo)準(zhǔn)所設(shè)計(jì)、制造；本產(chǎn)品的運(yùn)行軌道一條鋪設(shè)在車間吊車梁上，另一條鋪設(shè)在地面上的半門式起重機(jī)；適用于加工車間、貨場、港口碼頭等貨區(qū)裝卸和搬運(yùn)物料。
本產(chǎn)品可根據(jù)用戶對起重量、跨度、上下軌道高低差要求進(jìn)行設(shè)計(jì)制造，起重機(jī)工作級別一般為A3～A6級。

主要特點(diǎn)：
1.本機(jī)主要由兩主梁、兩支腿，上下橫梁，大車運(yùn)行機(jī)構(gòu)、小車及電氣設(shè)備所組成，主梁、上下橫梁、支腿均采用箱型焊接板結(jié)構(gòu)。

2.小車導(dǎo)電采用異形槽或工字鋼扁電纜滑車導(dǎo)電，整機(jī)供電般采用? 安全滑線或軟電纜供電。

3.大車運(yùn)行機(jī)構(gòu)采用“三合一”分別驅(qū)動方式。

4.各機(jī)構(gòu)可采用電阻器調(diào)速或變頻調(diào)速．

5.操縱方式可地面按鈕把操縱、地面遙控操縱或司機(jī)室操縱三種形式可選用。

????Different from MG and ME crane, MB semi-gantry crane has two tracks with different height.? One track is on the crane beam of workshop, the other is on the ground. It is applicable to work in processing workshops，storage yards and ports. Performance parameters, such as lifting capacity,span and lifting height，is flexible，customers may point out these data in accordance with actual situations by themselves.?Crane’s classification group is up to A5-A6

Main features：
??? 1. The machine is composed of two main girders,two legs,upper travelling mechanism ,low travelling mechanism,trolley and electrical system . Main frames are box-welded.
??? 2. Cable pulley with Slot-shaped or I-beam track is for?electrical conduct of crane trolley and circular-coppered?slip- line or cable drum is for the whole crane’s.
??? 3. Travelling mechanism adopts “three-in-one” respective?drive with hardened reducer.
??? 4. Resistor or variable frequency is applied for speed?adjustment in each mechanism.
??? 5. There are three kind of manipulation types：ground wired?button control ,remote control or cab’s.
