Safe use of hydra
This document provides guidance on the safe operation of a Hydra crane. It outlines proper procedures for marching with and without loads, including maintaining slow speeds, full boom retraction, and load stability. It emphasizes the importance of understanding load capacities and ensuring the load's center of gravity is properly positioned. Operators are instructed to lift within the crane's capacity, avoid unsuitable terrain, and not use the crane for inappropriate tasks like dragging. The document stresses the role of trained operators and helpers in preventing accidents.

- 4. The Rated Capacities Therated capacities are for lifting the load in straight unslewed position and level ground condition. It should not be taken as capacities for pick and carry operations. As the max. load acts upon the tyres, it is essential to maintain proper inflation pr. In all tyres

- 6. MARCHING WITHOUT LOAD •Traveling Speed without load should not be more than 10 km/h. • Boom should be fully retracted and hook block should be fully raised. • A Helper should always be available with the operator on the machine. While marching he should guide the operator about the safe distance from the things around the Hydra. • DON’T OVERTAKE any vehicle while marching • Always give indicators while traveling/ turning and stopping
- 7. MARCHING WITH LOAD •Maintain a max speed of 2-3 km/h. • Match with the speed of riggers/helper walking along with you. • Always travel in Low 1st gear and don’t change the gears while marching with load. • Load should not be at more than 0.5 meters height from the ground while marching. • Always march with boom fully retracted and in lowest convenient position. • Load should be stable while marching. • Always use tag lines
- 8. MARCHING WITH LOAD •Load should not sway left /right, forward or back ward direction, which may be caused due to uneven surface, lifting height of the load and length of wire rope from boom to hook block • Avoid Stopping/Lifting the Load with a Jerk • Over dimension item should not be taken for distance march. • Avoid gradients above 10% and travel with the load facing up the slope
- 9. CENTER OF GRAVITY •Hook should be placed right over the C.G. of the load • While marching ensure that CG should always fall between the Front Tyres
- 10. LIFTING LOADS • LiftLoads with Hydra in unslewed (central) position. • Plan the lift so as to minimize turning with load as far as possible. • Don’t use Hydra for long distances with the load. Instead use trailer. • Use Hydra within the capacity. • Don’t use Hydra for dragging or pulling the loads either sideways or back and forth.
- 11. POINTS TO BECHECKED BEFORE PLANNING ANY ACTIVITY OF LIFTING BY HYDRA • Load- Know the exact load to be lifted. No Guessing. Always refer to the load chart available with the Hydra/Crane • User should know the load and the capacity of the Hydra. He should be aware of the Load Chart of the machine being used for the job. • NO OVERLOADING • Check the Condition and capacities of Wire Rope, lifting tools and tackles. • Whether load is properly hooked or not.
- 12. Ground Condition /Side Slope • The terrain should be reasonably hard and should be able to bear the load of the crane. Soft, Marshy land is likely to bog down the crane. During rainy season beware of soft ground conditions and ditches. • Check for any Inclination, Any Soft Surface, and Uneven Ground. Always keep the loading area as level as possible. Check your route before marching with the load. • Never march on sideways sloping surface.
- 13. Avoid Accidents byavoiding ‘unsafe conditions and unsafe practices’ Most accidents ,whether they occur in the industry, on the farm, at home or on the highway, are caused by the failure of some individual to follow simple and fundamental safety rules or precautions. For this reason most accidents can be prevented by recognizing the real cause and doing something before accident occurs. Regardless of the care used in the design and construction of any type of equipment , there are many conditions that cannot be completely safe guarded against without interfering with reasonable accessibility and efficient operation. A careful operator is the best insurance against an accident .The complete observance if one simple rule would prevent many thousand serious injury each year. That rule is : Never attempt to clean, oil or adjust the machine while it is in motion. “National Safety Council”
