2.1 Lifting workers (driving operators) operators must be three tight, wear the employment certificate, women workers must be inserted into the helmet. Do not wear shorts, skirts, high heels, slippers.

Use and management of the metal structure of the crane 2.2, main parts, electrical equipment, safety devices should meet the requirements GB / T6067's.

2.3 Lifting workers must be trained in special technical training. Those who pass the examination of the competent department and concurrently issue the operating licenses can only be employed for independent operation.

2.4 Before operation, check whether the driving, spreader (hook, lifting ring, wire rope, chain, etc.) is normal; prohibit overload use; operating system, signal, limit switch, brake mechanism, etc. must be safe and reliable, after confirmation, Only work can be done.

2.5 When lifting the workpiece, hang it at the center of gravity and keep it balanced. Pedestrians are strictly forbidden under the hanging piece. Under no circumstances should the person be used as the counterweight. Before driving, you must carefully observe the presence of pedestrians and other obstacles around the top, bottom, left, right, and stairs, and ring first, no abnormalities to drive.

2.6 Focus on the lifting of the workpiece, listen to the signal of the ground person in accordance with the prescribed gestures; others should not send signals during the operation (exception in case of emergency); alarm should be issued when driving, so that the following personnel know the driving operation The direction of the two hooks of the towing drum shall not be activated at the same time; if the box is turned over or turned over, it must be directed by a special person.

2.7 When the crane is working, except for the outside of the control room, the rest of the place is not allowed to stand.

2.8 When testing or repairing on the crane, the crane must be powered off. When the crane is running without heavy loads, the hook is 2.5m away from the ground.

2.9 It is strictly forbidden for cranes to pass heavy objects from the head of the personnel when carrying heavy loads.

2.10 When the crane is running with heavy objects, the lowest point of the weight is at least 0.5m from the highest obstacle on the heavy-duty operation line.

2.11 It is strictly forbidden to transport or lift and lift personnel with hooks.

2.12 Tools, spare parts, fasteners, sundries, etc. must be stored in special boxes. It is forbidden to be scattered on the crane to avoid accidents of personal injury or equipment when the objects fall.

2.13 When lifting liquid metal, harmful liquids and important articles, no matter how much weight, you must first lift the heavy objects 150-200mm away from the ground, and verify the reliability of the brakes before starting normal lifting work.

2.14 Combustible items (such as coal, oil, etc.) storage is on the crane, crane fire prevention work.

2.15 The crane must be regularly inspected for safety, including static and dynamic loads on the crane using the test load.

3 Drivers should do the following before driving:

3.1 Understand the power supply situation, the crane should not be started when the power supply voltage (voltage between the conductors of the cart) is less than 90% of the rated value.

3.2 Carry out the inspection of the crane with the main switch disconnected, check the connection and use of the main part, and adjust the individual units.

3.3 Check for any remaining tools or other items on the crane to avoid falling down during work and personal or damage to the equipment.

3.4 Refuel the lubrication points of the equipment as specified.

4 The operator has the right to refuse lifting if one of the following conditions occurs: (10 does not hang)

4.1 The weight of the overloaded or suspended object is unclear;

4.2 The command signal is not clear and does not hang;

4.3 Bundling, hanging or unbalanced may cause sliding failure;

4.4 When the person is suspended or suspended, it is not suspended;

4.5 The structure or component does not hang when it has defects or damage that affect safety work;

4.6 Do not hang when there is an unclear embedded object;

4.7 The work site is dim and cannot be seen when the site, the object being lifted and the command signal are not visible;

4.8 When the corners of the object to be suspended and the bundled steel wire are not padded, they are not suspended;

4.9 Do not hang when lifting heavy objects;

4.10 The crane safety device is not complete, it is not reliable and does not hang.

Machining Titanium

In the process of machining titanium alloy, the titanium alloy material itself has low modulus of elasticity, large elastic deformation, high cutting temperature, low thermal conductivity and high chemical activity at high temperature, which makes the sticky knife phenomenon serious, easily aggravating the tool wear and even breakage, which leads to the poor machinability of the titanium alloy. Therefore, machining titanium alloy requires proper cutting tools and good machining technology.
