Rock bolt is the most basic part of roadway support in contemporary coal mines, it reinforced the surrounding rock of the roadway, make the surrounding rock support itself. Material: MG335/400/500/600 Size: diameter 18,20,22 mm Price: discussable and based on the quantity of your enquiry This is left-handed rock bolt, if you want konw more about the rock bolt,
U-steel support is a kind of passive support of coal mine support, the tensile strength and the compressive strength is higher, it also has good toughness properties Material: 20Mnk Size: 29U Application: U-channel steel support is mainly used for the secondary support of mine tunnel and the mine tunnel of the mountain tunnel. Application: U-channel steel support is mainly used for the secondary support of mine tunnel and the mine tunnel of the mountain tunnel.
Rail press also called welding rail press, welding steel rail fixing device,steel beam rail press, welding clamp, but no matter what do you call, its role is only a kind of fixed rail pressure.Usually welded on the steel i-beam, but sometimes also can be used in steel plates which embedded in concrete. Rail press can be divided into WJK, SWJK, HWJK series TG38, TG43, TG50, TG60, QU70, QU80, QU100, QU120 ,which consists of base, cover, wear of shaw, spring flat washer. With two kinds materials: one kind is half cast steel: cover for nodular cast iron, the base for cast steel. The other is a whole cast steel: top and bottom are cast steel.
Model: threaded bolt Specification: 18*2m, 16*6m (customize according to customer requirement) Material: 16Mn, 20Mnsi Characteristic: 1. The anchorage end and the fastening end do not require machining; 2. The strength is equal all the length, high material utilization; 3. Strong anchoring force; 4. Equipped with prestressed gasket, easy to control installation quality; 5. The installation speed is fast, it is a new type of anchor rod, which is a kind of material that save material and work, equal strength, and the left screw steel bolt has a wide application prospect.

Structure: 1) Ball nut: it can transfer the stress of surrounding rock to the pad. 2) Arch plate: can bear greater stress of surrounding rock. 3) Check plup plug: make the grouting maintain a certain pressure to fill the surrounding rock gap adequately. 4) Anchor bolt bar: the whole length of the intermational standard waveform connection thread, easy to install drill bit, coupling sleeve, fastening nut; and can be arbitrarily cut and connected to lengthen. 5) Bushing: so that the bolt can be lengthened to the design depth while drilling. 6) Broach: it has strong penetrating power, enabling the bolt to pass through all kinds of rocks. Characteristic: Self drilling bolt adopts good thick wall seamless steel pipe material, perfect and fast surface screw forming technology and well-made fittings, the function of drilling, grouting and anchoring has been realized. 1) There have a strong penetrating drill in front of the bolt, under the action of general drilling machinery, it can easily penetrate all kinds of rocks. 2) The bolt has a continuous international standard corrugated thread, which can be used as a drill pipe to complete the drilling of anchor hole. 3) The bolt body as the drill pipe does not need to be pulled out, and the cavity can be used as the grouting channel from inside to outside. 4) Hign efficiency grouting stopc ock enables grouting to maintain strong grouting pressire, fully fill the vold and fix the fractured rock mass, high stength washer and nuts can transfer the stress of deep surrounding rock evenly to surrounding rock, the purpose of mutual support between rock and anchor is achieved.
