Repair to the Bucket of the machine by dismantling the bucket from the machine, loading it in a vehicle and carrying to workshop for repairs. Repairs to the Bucket of the machine by taking out the toe plate using gas cutter and p/f of toe plate, repairs using MIG welding for joining of cracks, face hardening of the bucket using high ferrite stainless steel electrodes, strengthening of the bucket by welding cut pieces, ensuring resistance to corrorision and oxidation. Repairs to the side wear plate by using high ferrite Stainless steel electrodes, repairs to the top beam and bracket of the bucket by providing additional strength and finishing the same. The job includes cost of material, labour charges, to and fro charges, loading/unloading of the bucket at workshop, hire charges of tools and tackles required to executer the job.

Job Description: Procurement of 2 Nos. High-Pressure Hydraulic Hoses (8 ft, >200 Bar).This work includes the procurement, testing, and delivery of two high-pressure hydraulic hoses, each 8 ft (≈2.4 m) in length, designed for excavator–rock breaker service. The hoses shall be manufactured from synthetic rubber with multi-spiral high-tensile steel wire reinforcement and conform to IS 445:2002 / IS 444:2017, SAE 100R12 / SAE 100R15 or equivalent international standards for high-pressure hydraulic applications. Each hose shall have a minimum working pressure >200 bar, burst pressure ≥ 4× working pressure, and an operating temperature range of –40°C to +120°C.End connections shall be factory-crimped with compatible male/female fittings as per ISO 12151 / ISO 8434, ensuring zero leakage under pulsating load. Outer cover shall be abrasion-, weather-, and oil-resistant with spring or spiral guard protection suitable for breaker hammer movement.

Job Description for Machining & Reprofiling of Hydraulic Breaker Chisel into V-Shaped Tip. This job covers the precision machining, controlled reprofiling, and finishing of a hydraulic breaker chisel used with excavator-mounted hydraulic rock breakers in the 18–26-ton class. The purpose of the work is to reshape a worn or standard blunt chisel into a V-shaped penetrating tip, suitable for improved crack initiation and faster penetration in hard or stratified rock formations. The contractor shall undertake machining on a hardened alloy-steel chisel (typically 140 mm diameter for SYB250-class breakers) originally hardened to 52–58 HRC. The machining process will be carried out using an industrial bench grinder, lathe-supported grinding fixture, or heavy-duty cutting tools capable of working on high-hardness steel. The V-shape shall be formed with two symmetrical faces, maintaining an included angle between 60° and 75°, ensuring straight impact transmission and reduced side thrust during operation. Machining must be performed in a controlled manner to avoid thermal softening. Coolant-assisted grinding or staged dry grinding with (Complete job had from SBD)
