Dangerous goods transport vehicles have been subject to various policies for the special nature of transported goods. Compared with ordinary models, these policies have the rationality and necessity for implementation in all aspects of blasting equipment transport vehicles. What are the basic management systems?
Transporting bottled trucks with compressed gas and liquefied gas must install ventilation and fixtures;
2. Transportation of flammable and explosive special vehicles shall be equipped with conductive static rubber towing devices in compliance with the regulations;
3. For transporting bottles of compressed gas and liquefied gas at horizontal levels, if the internal dimensions of the compartment width do not reach the length of the cylinder, replace the vehicle that meets the transportation requirements;
4. Transport oxidants and organic peroxides must use van type temperature control vehicles;
5. The name of the dangerous goods name system shall be applied to the business scope of the special tanker trucks for transporting dangerous goods;
6. If a tank-type vehicle with a service life of seven years or more (based on the date of registration of the vehicle permit) does not match the tank volume and filling medium with the quality of the approved load, it must exit the dangerous goods operation column.
To sum up, in order to ensure the safety of transportation, the dangerous goods transporter must follow the above-mentioned relevant regulations to operate in order to ensure the smooth completion of the transportation process.
Tower cranes typically use a combination of fixed and movable pulleys to lift and lower heavy loads. The pulleys are usually attached to the jib or boom of the crane and are used to change the direction and increase the mechanical advantage of the lifting system.
Some common types of pulleys used in tower cranes include:
1. Fixed Pulleys: These are stationary pulleys that are mounted at a fixed point on the crane. They change the direction of the lifting force and help distribute the load evenly.
2. Movable Pulleys: These pulleys are attached to a movable block that can be raised or lowered along the jib or boom of the crane. They provide additional mechanical advantage and allow for easier lifting of heavy loads.
3. Trolley Pulleys: These pulleys are used in conjunction with a trolley system that allows the crane to move horizontally along the jib or boom. The trolley pulleys help distribute the load evenly and provide smooth movement of the crane.
4. Counterweight Pulleys: Tower cranes often use a counterweight system to balance the load being lifted. Counterweight pulleys are used to attach the counterweights to the crane and ensure proper balance and stability.
It's important to note that the specific configuration and number of pulleys used in a Tower Crane can vary depending on the crane model and lifting capacity.
