The core lifter, also known as the core catcher, is responsible for keeping the core inside the barrel and retaining it during wedge action. Core lifters from RDS Engineering are made of spring steel that has been suitably treated to add more spring action for a longer lifespan. To break the core sample, a core lifter case is required. The core lifter's tapered inside prevents it from sliding and allows it to grip onto the core sample. The core is kept inside the barrel using a core lifter or core catcher. Our core lifters are constructed from premium steel that has been precisely hardened for improved performance and longer life. Three essential components make up the core lifter assembly, which enables you to securely grasp the core sample and break it to bring it to the surface. Using the same source for all three pieces will assure optimal performance and provide the right distance between the core lifter, core lifter casing, and stop ring.

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 a full line of double tube core barrels in accordance with ISO Standards and DCDMA. Use: Double tube core barrels are used for a variety of purposes, including diamond core drilling, tunnel drilling, geotechnical analysis, soil testing, drainage, and grouting holes. Method: The inner tube is connected to the core barrel head by bearings in double tube core barrels, which allows the inner tube to rotate independently of the core barrel. The outer tube and inner tube of the double tube core barrel are filled with water. The inner tube bottom end has perforations that allow water to pass through. The only part of the core that is prone to corrosion is up to the diamond core bit. In relation to the overall length of the two tube core barrel, this distance is quite short. It is conceivable to accept a core made of softer and fractured materials once the erosion issue has been resolved. It delivers an improved rate of core recovery and little core erosion. Specification and standard size: AX double tube core barrel core diameter of 30.1 mm and a Drilling hole diameter of 48 mm. BX double tube core barrel core diameter of 42 mm and a Drilling hole diameter of 60 mm. NX double tube core barrel core diameter of 54 mm and a Drilling hole diameter of 76 mm. HX double tube core barrel core diameter of 76 mm and a Drilling hole diameter of 100 mm.
