Auto SPT Hammer RDS Engineering Manufacturing Standard Penetration Test (SPT) drop hammer that is hydraulically powered and entirely automated. The hammer produces a reliable and precise blow count using a 140 lbs driving force (slug) dropped from 76 cm, 760mm Adjustable. Both a swing-arm mounted variant and a solo winch line device are offered for the hammer. Both designs may be used for practically any equipment. Compared to conventional manual SPT procedures, the fully enclosed, hydraulic motor powered hammer is far safer. The straightforward, durable design minimises maintenance while maintaining great efficiency. For all RDS rig variants as well as typical rival equipment, we provide mounting and hydraulic connection kits. According to ISO 22476-3:2005, the RDS automated SPT hammer delivers exceptionally reliable and accurate Standard Penetration Test results. There are no wires or ropes to obstruct the weight's free fall, and a viewing hole enables you to confirm the 30 inch fall height. All moving parts, including the region that is likely to be hit by the weight or anvil, are also encased for safety. RDS Engineering installs more than 80 Auto SPT Drilling Rigs. Geotechnical Testing Equipment as per ISO 22476-3:2005 RDS Auto SPT Hammer Technical Specifications Hammer drop height: 760mm, 76cm, 30 inches, Hammer piston weight: 63.5 Kg, 140 lbs Blow per minute: 10-30 Adjustable System Energy test ratio (ETR): 67% - 80% Adjustable System SPT Assembly: SPT Sampler, SPT tube, SPT shoe SPT Anvil Connection: AW / Customize SPT Automatic Hammer Benefits 1. Easy to Upgrade Your Existing Rig 2. Tests with high reliability and accuracy (63.5 kg x 760mm drop) (140 lbs. x 30" drop) 3. Safety: the hammer's casing contains all of the working parts. 4. Can be applied to the majority of rigs (geotechnical, rotary, diamond core rig) 5. Accuracy results in N-value and SPT test, SBC Test Easy to Set Up The SPT (Standard Penetration Test) Hammer assembly is kept to the right of the drill frame and secured in place for travel. The Hammer must be raised using a hydraulic cylinder or hoist and placed above the drill rod in order to work. The Hammer case is lowered into the driving position so that it may be rapidly positioned above the borehole. Simple to Use The Hammer's design is straightforward, and a single operator can operate it successfully. Insofar as their performance doesn't depend on operator-controlled adjustments or monitoring, RDS SPT Hammers are totally automated. The weight of the slug is raised hydraulically via a continuous chain; Due to the Hammer case's ability to "float" in the self-compensating rack or on the hydraulic cylinder, the sampling procedure may be followed regardless of the material density. For better safety, the hitting surface is kept totally enclosed. The normal penetration test is carried out by the RDS Self-Compensating SPT Hammer without adding any extra weight or pressure to the drill string. This eliminates the possibility of retroactive loads or forces being applied to the drill string each time the mechanism cycles.

RDS Engineering manufactures diamond Reaming shells for NMLC triple tube for Diamond Core Drilling, Tunnel Drilling, Geotechnical Investigation, Soil Testing, Drainage, and Grouting of Holes, among other uses. The reaming shell, which is immediately above the diamond core bit, keeps the drill hole's outer diameter constant. The diamond core bit is joined to the core barrel by the diamond reaming shell. The reaming shell effectively reams the hole because its outer diameter is only a little bit larger than the core bits. The reaming shell serves as a link between the core bit and the outer barrel and is a crucial component of a diamond drilling system. In addition to stabilizing the drill string's bottom, it reams the hole to the right size. The drilling crew should regularly inspect the reaming shell's outer diameter since a worn-out or smaller reaming shell will cause the drill bit and drill string to become stuck. RDS manufactures great-quality synthetic and natural diamonds that are placed in a matrix with great resistance and is used to create reaming shells. On the leading edges of the ring, friction-resistant tungsten carbide inlays offer extra security and a longer lifespan. Diamond reaming shell for NMLC triple size core diameter of 48 mm and a Drilling hole diameter of 76 mm.
