Product Description

The LH electric hoist bridge crane is designed and manufactured according to the standard JB/T3695-1994. It is used with fixed electric hoists in the form of CD1, MD1, etc. The double main beam structure bridge crane with the trolley running on the track laid by the main beam , Its applicable lifting weight is 1-32t, the applicable span is 7.5-31.5 meters, and the working environment temperature is in the range of -25-+40℃. This product is a general purpose crane, which is mostly used in places where the frequency of application is low or the number of times of rated lifting is small, such as machinery manufacturing, assembly, and warehouses. Advantages: good stability in use, full utilization of the workshop headroom to obtain a higher effective lifting height, moderate price; Disadvantages: low work level, not suitable for heavy workshops. The crane is equipped with three control modes: bottom surface, control room and remote control. The control room is also equipped with two types of door opening and side opening for users to choose and use. Note: (The local factory supplies 10% below the market price, free on-site surveys, fast customized production and installation, if there are any quality problems in the later use of the product, including human factors, 30-60 minutes to start the emergency maintenance program).

 

Features:

This series of products consists of four main parts: bridge, trolley, cart operation and electrical. A fixed electric wire rope hoist is used as the lifting mechanism. The crane assembly test should meet the requirements of "GB/T3695-1994". When installing the crane, it must be installed in accordance with the provisions of the attached drawings.

When the crane is disassembled, transported and installed, the connection of the end beam must be disassembled and assembled according to the drawings.

The lifting capacity of this series of products is divided into two types: cab control and ground control. When operating the cab, there are six tonnages of 5t, 10t, 16t, 20t, and 32t, of which three tonnages of 16t, 20t, and 32t are equipped with 3.2t, 5t, and 10t as auxiliary hooks.

means: 16/3.2t, 20/5t, 32/10t; during ground control, there are only three tonnages of 5t, 10t, and 16t, with a span of 10.5-25.5m.

(1) Bridge

The bridge frame is composed of main beam, end beam, walking platform, conductive frame, maintenance cage, driver's cab, railing and ladder.

This series uses a four-beam structure, and the main beam and end beams are connected by bolts. The feeder of the trolley adopts a flexible cable power supply system. This series has designed two types of driver's cabs, open and closed. The walking platform on the non-conductive side is widened at both ends for maintenance and placement of electrical equipment. There is a standard section in the middle and a section of 3 meters. The number varies with the span. It is easy to manufacture and install. The other side of the bridge frame is provided with a conductive frame for the trolley, which is installed on the walking platform for hoisting the flexible cable power supply system. In order to facilitate the maintenance of the conductive system of the cart, a maintenance cage is provided on the power supply side of the bridge frame. The cab is equipped with two types of closed and open. The shell structure is formed by stamping, and the whole is connected by bolts to reduce welding deformation. The field of view of the cab is greater than 280 degrees. It uses aluminum alloy window frames and all glass uses tempered glass (or Laminated glass).

The lifting mechanism on this series of trolleys adopts the CD (MD) electric hoist with good performance produced by our company.

The trolley frame is composed of beams and longitudinal beams. The longitudinal beams and cross beams are welded by channel steel and steel plates, and the beams are connected by welding.

(three) cart

The operating mechanism of the cart is driven separately, and the number of driving wheels is 1/2 of the total number of wheels.

(four) electrical system
