(1) When using the drilling rig to drill, the driver should be placed in the drilling position, so that the front end is against the rock, and the distribution should be careful to let the drilling rig move forward, so that the drill bit touches the rock; When opening the hole, first quietly let the drilling rig drive, when the drill rod is in place in the rock, it is allocated to the full open position.
(2) Before starting the drilling rig, check whether the charging pressure of the accumulator is normal; Check whether the scouring water pressure and the lubricating air pressure can be; Check whether there is sufficient lubricating oil in the lubricator, and whether the oil supply is appropriate; Check the reverse tendency of the oil pump motor. (3) If the drilling rig cannot open the hole smoothly, it should first assign the rock drill to retreat, and then let the rock drill move forward to open the hole from the beginning.
(4) When replacing the drill bit, the drill bit should be gently pressed against the rock, so that the motor of the drill can be reversed to complete the sensitive unloading head.
(5) The inspection of hydraulic components can only be prevented under the condition of pole cleaning, and after the connecting tissue is removed, it must be quickly plugged with the cleaning tightly matched plug. Before the repaired rock drill is used from scratch, it is necessary to circulate the hydraulic oil into the oil circuit to wash the components of the hydraulic system.
(6) The oil level and oil supply of the lubricator should be checked regularly; The gear with reverse structure is regularly filled with high-temperature grease; Check the oil level in the lubricating oil tank regularly and remove the dirt in the oil tank

  • Artistically, aluminum window channel extrusion opens up a realm of possibilities for architects and designersaluminum window channel extrusion. The ability to create customized profiles enables the realization of unique architectural visions, where windows can seamlessly integrate with the overall design scheme. This flexibility allows for the creation of visually stunning buildings that push the boundaries of traditional architecture.
  • How to maintain Aluminium Window Profile
  • When we’re designing a custom iron fence or railing, we offer customers the option to add decorative elements made from cast iron to an otherwise wrought iron structure. Those pieces are then welded onto the pickets of the railing. This process can save on costs, since producing intricate decorative designs in wrought iron through hand forging can get expensive.

  • Anodized

  • In addition to their durability, double hole lock boxes are also very secure. By encasing the lock within a metal box and providing two holes for the lock to go through, these lock boxes make it extremely difficult for would-be intruders to tamper with the lock or gain access to the gate. This added security feature can provide peace of mind to property owners, knowing that their gates are well-protected.
  • In the world of interior and architectural design, every detail matters. One such detail that often goes unnoticed but plays a crucial role in aesthetics and usability is the hardware used on doors and cabinets. Among the myriad options available, stainless steel finger pulls have emerged as a popular choice for both residential and commercial settings. These sleek and modern fixtures not only enhance the visual appeal of spaces but also offer a multitude of practical benefits.
