Overhead Crane & Lifting Equipment Forging Specialists
Shivam Forge is a specialized crane parts forging manufacturer in India producing crane hooks (IS 3815), pulley sheaves, crane wheel flanges, trolley components, hoist drum pins, and rigging shackles in EN24, SAE 4140, and alloy steel from Shapar GIDC, Rajkot. ISO 9001:2015 certified. Export to 12+ countries. Safety-critical components with full material traceability.
Overhead cranes, gantry cranes, EOT cranes, and jib cranes operate in environments where a single component failure can result in loss of life and catastrophic property damage. The crane hook, sheave block, cross-traverse wheel, and hoist drum pins are all forged components — and for good reason. Closed-die forging produces the homogeneous, porosity-free metallic structure with aligned grain flow that lifting equipment designers depend on for reliable performance across rated service cycles. Shivam Forge has been producing forged crane components to IS 3815, IS 2062, and EN 13001 equivalent specifications for over 20 years from our Rajkot facility.
Single-shank crane hooks (C-hooks) and double-shank crane hooks forged in EN24 and C45 to IS 3815 dimensional and mechanical property requirements. Forged hooks are trapezoidal cross-section — the standard section optimized for bending load distribution in the hook shank. Machined saddle radius, latch boss groove, and shank thread produced from forged blank. Capacity range 0.5 tonne to 200 tonne. Proof-load tested at 2x WLL.
Crane block sheaves and wire rope groove pulleys forged in C45 and EN24 for EOT cranes, overhead hoists, and ship deck cranes. The rope groove profile is machined after forging from a near-net forged blank — groove radius tolerance held to ±0.1 mm. Solid forged sheaves have no internal porosity risk at the hub bore or web section, unlike cast iron sheaves that regularly crack at the boss transition.
End carriage and cross-traverse crane wheels forged in C45 and 50Cr with induction-hardened tread and flange surfaces to 50–58 HRC. Forged crane wheels have consistent through-section hardness and no casting defects at the hub-to-rim transition. Produced in wheel diameters 125 mm to 710 mm to IS 3443 and CMAA specifications. Bored and keyway-slotted on CNC after forging.
Large-diameter end carriage assembly pins, equalizing beam pivot pins, and buffer mounting pins forged in EN24 and SAE 4140 for EOT bridge crane structural assemblies. Pin diameters from 40 mm to 200 mm, lengths to 800 mm. Magnetic particle tested (MPT) after final machining — critical for detecting any surface or sub-surface linear indications before assembly.
Hoist drum shaft stubs, drum end flanges, and rope drum trunnion pins forged in EN24 and 42CrMo4. The trunnion shaft is the primary load path between hoist drum and the structure — failure here is catastrophic. Forged shaft with upset flanges ensures grain continuity at the fillet radius — the highest stress concentration point in the assembly.
Hook block crossheads, snatch block side plates, yoke plates, and sheave axle pins forged in EN24 and IS 2062 for overhead crane hook block assemblies. The crosshead is the structural backbone of the hook block — it carries the resultant sheave loads and connects to the hook shank. Forged construction eliminates weld seams at load-bearing cross-sections.
Bow shackles and D-shackles in Grade S and Grade 8 alloy steel, drop forged and quenched-and-tempered for crane sling rigging. WLL 0.5 tonne to 35 tonne. Screw-pin and bolt-nut types. Proof-load tested at 2x WLL with batch certificates. Compatible with EN 13889:2003 requirements for construction and crane use.
Pin eyes, clevis ends, and adjustable bracket fittings for fabricated lifting beams and spreader bars forged in EN24. The end fitting is the weakest point in a poorly designed lifting beam — forged eyes with radiused inner bore distribution are critical for rated capacity. We supply end fittings to lifting beam fabricators' drawings.
Crane rail clips, Gantrex-style hold-down clips, and base plate anchors forged in IS 2062 and EN8 for crane rail installation. Forged rail clips provide consistent clamping force and are dimensionally more accurate than pressed or flame-cut alternatives — critical for maintaining gauge on long bridge crane runway girders.
End stop buffer heads and impact absorber plates forged in mild steel and alloy steel for crane travel limit protection. Buffer heads are repeatedly impacted by crane end carriages during travel limit operation — forged steel construction with no weld seams at the impact face ensures predictable deformation behavior.
Forged pivot brackets and pivot pin assemblies for multiple-point lift equalizing beams used in load cell testing rigs, large structural lifts, and industrial handling equipment. The pivot must freely articulate under load — forged pin holes are machined to tight running fits (H8/f7) for reliable performance.
Wall-mounted jib crane bracket arms, collar mounts, and jib pivot pins forged in IS 2062 E300 and EN24. The jib bracket transfers crane loads directly to the building structure wall — a weldment here is a maintenance liability. Forged brackets eliminate wall-mount weld fatigue cracking that causes jib crane collapses.
Our crane hooks are produced to IS 3815:1999 requirements covering dimensions, mechanical properties, and marking. The standard specifies 1 tonne to 100 tonne hook capacities in Type 1 (single shank), Type 2 (dual shank), and shank thread form. We can also produce hooks to DIN 15401, FEM 1.001, and EN 1677 series standards for European market requirements.
All crane hooks, crossheads, and shackles undergo 100% magnetic particle testing (MPT) after final machining. Trunnion shafts, large pins, and yoke plates are UT tested for internal indications. NDT is performed by trained Level-II certified personnel per IS 3658 (MPT) and IS 4260 (UT) procedures.
Crane hooks, shackles, and rigging hardware are proof-load tested at 2x WLL (or as specified per IS 3815 table) using calibrated testing machines. Test date, load applied, equipment serial number, and component identification are recorded on each proof-load certificate issued with the batch.
Each crane forging lot is traceable to the raw material heat number from the steel mill. Mill test certificates, internal heat numbers, and forging lot numbers are maintained in our quality records for the life of the component. This traceability is essential for in-service inspections and crane overhaul documentation.
Export customers and Indian clients with international project requirements receive EN 10204 3.1 material test certificates from our approved testing labs. This certification is required by most European crane standards (FEM, EN 13001) and by clients under ISO 9001 supply chain audit requirements.
For new crane component programs, we produce FAIR (First Article Inspection Report) covering all drawing dimensions with actual measured values. CMM-generated reports are available for complex geometries. Production batches are sampled dimensionally per AQL 1.0 inspection level.
Crane components operate in the most safety-critical environment in industrial manufacturing — a hook or sheave failure does not just mean a production stoppage, it can mean lives lost and equipment destroyed. This is why crane component designers and procurement teams consistently specify forged steel over cast, fabricated, or built-up alternatives. Shivam Forge, operating from Shapar GIDC, Rajkot for over 20 years, manufactures crane hooks to IS 3815, pulley sheaves, traversing wheels, hoist drum trunnion shafts, and complete rigging hardware for EOT crane manufacturers, crane rebuilders, and industrial material handling OEMs across India and in 12+ export countries.
Our crane hook production begins with EN24 or C45 billet sourced from approved Indian steel mills with mill test certificates. The billet is heated to forging temperature, closed-die forged to the IS 3815 blank shape, trimmed, and then normalized or quench-and-tempered depending on the capacity and material specification. The machined hook undergoes 100% magnetic particle testing by Level-II NDT personnel, proof-load testing at 2x WLL on calibrated hydraulic testing machines, and dimensional verification before the IS 3815 marking is stamped and the component is released with a full documentation package. This is the level of rigor that crane manufacturers and plant engineering departments expect — and that Shivam Forge has been consistently delivering for two decades.
Beyond crane hooks, our lifting equipment forging portfolio covers the full range of overhead crane structural and mechanical components. Crane traversing wheels in C45 with induction-hardened treads and flanges (50–58 HRC) are produced to CMAA specifications in diameters from 125 mm to 710 mm. Pulley sheaves with precision-machined rope grooves for 6 mm to 60 mm wire rope diameters are produced in C45 and EN24. End carriage pins, equalizing beam pivots, and hoist drum trunnion shafts in EN24 and 42CrMo4 are produced with full NDT inspection. Each of these components can be supplied as rough forging, heat-treated blank, or fully machined finished component depending on the customer's manufacturing process.
Export customers for crane forgings — particularly in the UK, Germany, and UAE — demand documentation that aligns with EN and ISO standards. We routinely supply EN 10204 3.1 material test certificates, proof-load test records, MPT and UT inspection reports, and dimensional inspection certificates in English, enabling our customers to maintain ISO 9001 audit trails and comply with Machinery Directive or LOLER (UK) requirements for lifting equipment traceability. Our documentation package is built into the standard supply process — not an add-on that delays delivery.
