overhead gantry cranes Manufacturing

explosion proof electric hoist Manufacturing units shall have obtained the lifting machinery manufacturing license, before engaging in a corresponding manufacturing activities.
Lifting machinery manufacturing licensee classification management, manufacturing units made manufacturing license shall have appropriate conditions for the implementation of the specific requirements of technical specifications in accordance with the relevant safety and other regulations.
Lifting machinery manufacturing license is valid for four years.
Manufacturing license period shall expire on the renewal application written six months ago; after examination, licensing authorities should make the decision to grant the license or not to license before the expiry date.
Hoisting Machinery Manufacturing expiry without renewal of the license, shall continue in lifting machinery manufacturing activities.
Manufacturing units shall adopt technical specifications meet the safety requirements of the lifting machinery design files.gantry crane manufacturerIn accordance with the requirements of safety specifications, type tests should be lifting products, lifting machinery parts or trial of new products, new parts, must be the whole or part of the type test.
Lifting machinery manufacturing process should be in accordance with the scope of the technical specifications and other safety regulations, and requirements of the project, from the manufacturing location of inspection and testing institutions supervision and inspection.Manufacturing units manufactured in the workplace should be permitted lifting machinery; but the structure can not be split and transport overrun, you can use the on-site manufacturing, from the location of the manufacturing site inspection agency supervision and inspection in accordance with safety specifications and other requirements.
Manufacturing units shall be the main force structure (the main beam, main boom, the main support legs, standard section, the same below) for all orders processed or purchased and used in lifting machinery.
The main part of the force structure required to purchase or commission processing, manufacturing units should be entrusted to obtain the appropriate type and level of qualification of lifting machinery manufacturing units processed or purchased mainly by the force structure of its processing and for lifting machinery.
When lifting machinery factory, it should be accompanied by the design documents (including the total figure, mainly due to the force structure diagrams, mechanical drawings and electrical transmission, hydraulic system schematics), product quality certification, installation and use and maintenance instructions, supervision and inspection certificate, about the type test certificate and other documents.

electromagnet overhead crane control system in the crane size vehicle control principle

This article will introduce the electromagnet overhead crane control system in the crane size car control principle:
SCM central processing system, real-time status and position information gathering work of the master switch, the central processor via the control unit for information processing, the use of 485 to achieve information from the control unit to the execution unit of transmission, thus completing the electromagnet overhead crane size car motor control, and then realize shipbuilding gantry crane left and front right information and the car stalls, control, rear and gear information.The size of the vehicle control system panel is shown in two shows:
Mute switch: turn on the switch, turn off the sound travels carts; turn off the switch, turn on the sound travels carts;
Hammer instructions: Tips reached the limit height;
Hammer Reset: height when it reaches the limit, use the hammer reset button in special circumstances can lift limit increase;
Operating lever: front push each car five stalls, each pushing carts around five stalls, to the execution unit can transmit different instructions;
Phase voltage switch: Turn the switch can adjust voltmeter shows AB, AC, BC, the voltage value of any two phases.

industrial overhead cranes control system replacement parts

industrial overhead cranes control system contains a large number of components, parts are all life, and therefore industrial overhead cranes control system after long-term use will inevitably need to replace some parts. This article is to explain the replacement double girder overhead travelling crane control system components.
If the component fails, the need to pay attention to the compatibility of the replacement parts.
If the solid state relay failure, you need to pay attention to:Solid-state relays are key components, the first wife of marine science and technology solid state relays have to undergo rigorous testing and screening, the technical indicators on the market for sale than ordinary solid state relays; and products from different manufacturers, pin locations are often different arrangement, user error take the case of repeated occurrence, in order to ensure reliable operation of the controller, it is recommended to buy spares from my company.
Need special tools to install a solid state relay replacement. To ensure reliable recommends that users install the control system will fail to return the company to repair.
Note: You must replace the parts by professionals. Do the leads or metal objects left in the machine to avoid fire;
Danger Never remodel JH-DSC, Otherwise, electric shock, accidents; after replacing the motherboard, you must run before the corresponding parameter settings, otherwise there is a risk of damaging the JH-DSC
