STRUCTURE
The crane structures designed to handle the extreme operating condition stipulated 
in the specifications. 
The girder structures either of fully welded rectangular or trapezoidal mono-box or 
twin box or plate girder constructions. The legs, portals and sill beams of fully welded box type structure made from mild steel plates conforming to BS4360 grade43. Lifting lugs for the whole crane by a mobile crane provided on the top of the legs.
In designing for fatigue the crane shall be considered as subject to 2,000,000 cycles of operation and the weight handled taken as the safe working load of 40 tonne below 
the spreader.
STRUCTURE CLASSIFICATION
(a) Class of utilization - U7 (two million loading cycles) 
(b) State of loading - Q 2 
(c) Group classification - A 7 
(d) Impact factor - 1.3 
(e) Duty factor - 0.95
(f) Nominal load spectrum factor - 0.63 of rated capacity.
(Or as your requirement)
 
MAIN HOIST:: 
The wire ropes reeving configuration, and sheaves of the main hoist system designed to ensure that wire ropes do not dislodge from the sheaves (or jump off sheave groove) under any operating condition. The design shall prevent excessive slackening of the main hoist ropes and also limit the hoisting speed when the ropes are slack. Slack rope condition monitored through the load cells and back-up by limit switches installed at the girder end. Load cells provided for every hoist ropes. 

AC motors used for the main hoist system. The motors coupled to the reducer through gear couplings or flexible coupling. 

Two sets of fail safe disc brakes assemblies be fitted on the drive. The braking torque of each set of brakesat least 150% of rated load torques. Normal container handling operation with loads up to the rated capacity possible with only one set of brakes.
 
SPREADER LIST, TRIM AND SKEW ADJUSTING DEVICES: 
The Crane equipped with spreader tilt and skew adjustment devices. The devices of sufficient stroke to tilt the spreader with a rated load to at least ±3 degrees (about a vertical plane). Sufficient clearance maintained between any part of the spreader (with flipper at raised position) and crane structures (e.g walkway leading to operator cabin) especially when trolling and spreader is tilted or skewed to the maximum. Tests for above requirement conducted during acceptance, testing and commissioning of the cranes.
 
OPERATOR'S CABIN
The operator's cabin firmly secured in a fail safe manner. The roof inclined 
to drain away rain water. Safe passage or walkway provided from the yard side leg to enable the operator to enter the cabin from the rear through a sliding door. Safe and easy 
escape from the cabin at any trolley position made possible for emergency purposes 
without having to move the trolley back to the parking position.
It's not suitable for lifting blazing & melting metal or toxicant 
as well as explosion-proof or insulating working conditions.

SAW Wire

The Gas Protection Welding Wire is a type of copper-plated low alloy steel gas shielded Welding wire, using carbon dioxide or argon-rich as the shielding gas for welding. It has excellent welding process performance, stable arc combustion, less spatter, beautiful weld forming, small sensitivity of weld metal porosity, good welding technology in all position, and can be suitable for a wide range of welding current.

Quick details:

1. Type: CO2 wire/SG2 welding wire/ Mig wire/ GMAW wire
Solid welding wire/ Gas shielded welding wire
2. Raw material: MIld steel/ Carbon steel/ Qingdao steel wire
3. Surface:Copper coated

4. Application : Co2 shielded welding, welding of mild steel material,
Ship/bridge welding, Arc welding etc.
