A Grúa pórtico de una sola viga consists of a bridge frame, a trolley equipped with a lifting mechanism, a trolley operating mechanism and a control room:
Gantry crane is a variant of Fabricante de grúas pórtico de una sola viga, also called gantry crane. It is mainly used for loading and unloading operations in outdoor cargo yards, material yards, and bulk cargoes. Its metal structure is like a door-shaped frame, with two legs installed under the main beam, which can walk directly on the track on the ground. Both ends of the main beam can have outstretched cantilever beams. Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port cargo yards.
1. El Fábrica de grúas pórtico de una sola viga Sevencrane frame is the basic component of the bridge crane, which is composed of the main beam, end beam and other parts, that is, the trolley. The main beam spans over the workshop, and its two ends are connected with end beams. The outside of the main beam is equipped with a walking platform and safety railings; the bridge is equipped with a cart moving mechanism, an electrical box, a lifting mechanism, and a trolley of Shandong Huiju Heavy Industry Technology Co., Ltd. Running track and auxiliary slide frame. One end of the bridge is equipped with the cab, and the other end is equipped with the main slide line for introducing power.
2. The moving mechanism of the cart is composed of driving motor, brake, transmission shaft, reducer and wheels. Wireless remote control single beam gantry crane companys driving methods include centralized driving and separate driving. At present, most of the bridge cranes produced in my country adopt separate drive mode, which has the advantages of light weight, convenient installation and maintenance. The entire crane is driven by the trolley moving mechanism and moves forward and backward along the length of the workshop. The trolley running mechanism consists of a trolley frame, a trolley moving mechanism and a lifting mechanism.
3. The trolley frame is welded from steel plates, and is equipped with a trolley moving mechanism, a lifting mechanism, railings and a lifting limit switch.
3.1 The trolley can move left and right along the track on the main beam of the bridge. Buffers and limit switches are installed at both ends of the trolley’s movement direction.
3.2 The trolley moving mechanism consists of a motor, reducer, reel, brake, etc. After deceleration, the motor drives the driving wheel to move the trolley.
3.3 The lifting mechanism consists of a motor, reducer, reel, brake, etc. The lifting motor is connected to the reducer through a brake wheel and coupling, and the output shaft of the reducer is connected to the lifting drum.
4. The control room is the pod for operating the La mejor grúa pórtico de una sola viga a la venta, also called the cab. There are control devices for large and trolley moving mechanisms, lifting mechanism control devices, and crane protection devices in the control room. The control room is generally fixed at one end of the main beam, and there are also a few that are installed under the car and move with the car. There is a passageway above the control room. The hatch of the walking platform is used for personnel to get up and down when inspecting the mechanical and electrical equipment of the cart and trolley.
5. Car conductive device (auxiliary slide wire).
6. Crane main power conductive device (main slide line).
7. AC magnetic control box and resistance box.
8. Orbit.
