The tractor must pay attention to the connection between the tractor and the semi-trailer in the process of connecting the flat-bed semi-trailer. The key points are the connection of the traction seat and the traction pin and the connection of the electrical circuit. Saddle and traction pin connection Before connecting, carefully check whether there is enough grease on the surface of the tractor saddle plate. Whether there is foreign matter on the traction pins or the traction slide plate of the flatbed semi-trailer, ensure that the traction skateboard is clean. 1. Adjust the support legs so that the flat-bed semi-trailer traction skateboard can adapt to the height of the traction saddle. Generally, the semi-trailer traction slide should be 1-3 cm lower than the center of the upper plane of the traction saddle. Take care not to be too high. Otherwise, sometimes not only can not be connected, but also damage the tractor, tractor pins and related parts. 2. Operate the traction seat locking mechanism to open the locking block to a free state. 3. When the tractor is rewinding, the centerline of the tractor-platform and the semi-trailer strives to be consistent, and the centerline offset of the two vehicles is limited to 40 mm or less. After the saddle seat of the tractor is aligned with the traction pin, the vehicle is slowly reversing until it hears a “click†sound, and when the locking block returns, the tractor and the flat semi-trailer are successfully towed. 4. Check whether the tractor locking block locks the traction pin and whether it is securely locked. 5. Advance the tractor slightly and check that the connection is good. Electrical connection between tractor and flatbed semi-trailer 1. Attach the two trachea joints (commonly known as handshakes) on the tractor to the two air fittings on the flatbed semi-trailer. The air supply line of the tractor is connected to the air supply line of the semitrailer, and the control line of the tractor is connected to the control line of the semitrailer. 2. After the gas connections are connected to each other, unscrew the semi-trailer air circuit connecting the disconnect switch on the tractor to make it ventilated. Otherwise, the air supply to the flatbed semi-trailer brake system cannot be performed, and the brake system cannot work. 3. Start the engine, observe the barometer of the cab, and increase the pressure in the air tank of the tractor and flatbed semi-trailer to the specified pressure. 4. Check for gas leaks and check that the brake system is working properly. 5. Insert the cable connector of the tractor into the seven-hole socket on the front of the flatbed semi-trailer until it snaps onto the seven-hole plug. 6. Check if the electrodes are well connected and confirm that the lights such as the taillights are working properly.

Tooling for special tooling / fixtures /
general standard tooling (similar to standard).
Fixture,or Mechanical Fixtures,as its name
implies, is used to clamp the workpiece clamping device (or guide tool).
Die: the device to define the shape and size
of the production object.
The tool: use in mechanical manufacturing
tool basically used for cutting metal materials, so the "tool" is
generally understood as metal cutting tools,like Diamond Tools.
AIDS: generally refers to connect tool and
machine tool.
Instrument: use various devices to store
the production of objects or tools at work or in the warehouse.
Check gauge: equipment inspection in the
production use.
Fixture: manufacturing systems, the word
corresponding to fixture, sometimes work with synonyms, sometimes also refers
to the general fixture, Taiwan / Japanese / Korean electronic enterprises to
use the word. Belongs to the fixture industry A containing fixture, belonging
to a subordinate relationship.
Application:
The fixture is used for machining workpiece
fastening quickly, when the machine tool, workpiece holding device, process
correct relative position. That is to say workholding fixture processing
machinery is an indispensable component in the machine tool technology to
high-speed, efficient, precise, complex, intelligent, environmental protection
direction driven by the fixture technology towards high fine, efficient, module
combination, general economic development. Also called fixture fixture. Broadly
speaking, any process, in the process for rapid, convenient and safe
installation device of the workpiece can be called the fixture. Such as welding
fixture, test fixture, assembly jig, fixture and so on. The fixture is the most
common, often referred to as the fixture. In the processing machine parts, in
order to make the surface of the workpiece to achieve drawing size
requirements, geometry and other surface the mutual position precision, before
processing The workpiece must be installed (location), to (clamp). Application
of machine tool fixture, to ensure the machining accuracy, stable product
quality; to improve labor productivity and reduce costs; improve the working
conditions of workers, to ensure safe production; to expand the scope of
machine tool technology, to achieve a "machine" the positioning
element (usually by the fixture. Determine the correct position of a workpiece
in the fixture), clamping device, tool guide element (to determine the tool and
workpiece relative position or direction guiding tool), indexing device (processing,
so that the workpiece can complete the number of stations in a single setup of
the rotary indexing device and mobile line dividing device two), connecting
element and fixture (jig base) and other components.
