Luffing jib tower crane functional uses

Luffing jib tower crane functional uses

The boom types of tower cranes are divided into two types: horizontal type and pressure rod type. When the boom is horizontal, the load-carrying trolley runs luffing along the horizontal boom, and the luffing motion is balanced. The boom is longer, but the weight of the boom is larger. When the boom is of the pressure rod type, the luffing mechanism drags the boom to pitch and change its amplitude. The luffing motion is not as smooth as the horizontal type, but its dead weight is smaller.

Use and maintenance of Roots blower

Use and maintenance of Roots blower

During normal operation, check the temperature of the bearings, lubricating oil in the oil tank, motor, etc. every 1 to 2 hours. They must not be higher than the specified value. Roots blowers make a lot of noise during operation. In order to reduce the noise, in addition to installing a muffler, sometimes some simple methods can also be used to reduce the noise, such as using the underground method. Dig a 4-5m³ underground hole, seal the upper cover of the hole, use a duct to introduce the air inlet into the crypt, and use another duct to introduce outside air into the crypt. The two conduits should be stepped into the bottom of the cave as much as possible, which can reduce a lot of noise.
