Traveling end beam is an important part of the electric traveling crane, which carries the lifting mechanism and load, and realizes the movement through the mechanism of speed reducer, electric motor and gear transmission. The following is a detailed introduction to the structural principle of traveling crane endcarriage movement:
Driving device: The driving device of traveling end beam usually consists of electric motor, reducer and coupling. The motor provides the power, the reducer converts the high speed rotation into low speed and high torque output, and the coupling transmits the speed and torque to the traveling end beam.
Gear transmission: The motion of the traveling end beam is mainly realized by gear transmission. Gear transmission can transfer the low-speed and high-torque torque output from the motor to the traveling end beam, and meet the high load and high-speed working requirements through the modulus and number of teeth design of the gear.
Braking device: In order to ensure the safety of traveling endcarriages during stopping, a braking device is usually provided. The braking device can hold the endcarriage in the desired position by means of electromagnetic suction or mechanical braking to prevent unwanted movement.
Guide rails and wheelsets: The movement of traveling endcarriages depends on guide rails and wheelsets. The guide rail is usually composed of steel rails or U-channels, which are used for the movement of the endcarriage beams; the wheelset is composed of wheels, bearings and support frames, etc., which enable the endcarriage beams to move along the guide rail.
Control system: In order to realize the precise control of the traveling end beam, a control system is usually set up. The control system can realize the monitoring and control of the parameters such as motor speed, travelling end beam position and lifting mechanism through PLC or computer, so as to realize the automated production process and precise material handling.
The motion structure of traveling endcarriage is a complex system engineering, which needs to consider the influence of several factors, including the output characteristics of the drive device, the design of gear transmission, the matching of the guide rail and wheel set and the stability of the control system. Through reasonable design and debugging, the traveling endcarriage can be made to meet the material handling requirements in different scenarios.
MH type electric hoist gantry crane is used together with CD MD model electric hoists.
L Type electric hoist gantry crane match with CD1/ MD1, HC type Electric Wire rope hoist, to lifting and transporting the heavy materials, mainly use indoors and outdoors.
BMH Type Semi Gantry Crane is a bridge-type crane whose bridge is supported on the ground track through outriggers on both sides.
A-type Double Beam Hook Gantry Crane, It is mainly composed of a gantry (main beam, outriggers, lower beam, etc.), a lifting mechanism, a running mechanism and an electronic control part.
The rail-mounted container gantry crane (English abbreviation RMG) is one of the special machines for container yards.
MZ Type Double-beam Grab Gantry Crane are mainly used in conjunction with bridge cranes, port cranes, and winches. They are widely used in ports, power plants, docks, chemical industries, etc. to grab various types of loose accumulations, such as ore, coal, slag, etc.
Winch Gantry Crane are used in open warehouses, windy areas, material stocks area, bridge building, concrete industry, cement plant, granite industry, construction industry, engineering industry, port, transportation, construction, dockyard, and other building sites for lifting and loading unloading objects.
U Type Subway Turn Slag Hook Gantry Crane also known as subway slag flipping machine, slag flipping gantry crane, slag flipping gantry crane, etc., is a specialized gantry crane used for excavation in subway and tunnel construction projects.
