Hoist and Gear Operations
![Page 6: Shipbreaking Module 4: Heavy Equipment & Material Movement 4.1 Hoisting, Emergency, Inspect Susan Harwood Grant Number SH-17820-08-60-F-23](https://reader035.vdocument.in/reader035/viewer/2022062515/56649d0b5503460f949deb1c/html5/thumbnails/6.jpg)
Cranes and heavy material moving equipment are extremely important to the operations of ship breaking.

![Page 7: Shipbreaking Module 4: Heavy Equipment & Material Movement 4.1 Hoisting, Emergency, Inspect Susan Harwood Grant Number SH-17820-08-60-F-23](https://reader035.vdocument.in/reader035/viewer/2022062515/56649d0b5503460f949deb1c/html5/thumbnails/7.jpg)
Without it shipbreaking would be extremely labor intensive and unsafe.

But with the usage of the equipment comes safety concerns that can result in injury and death.

There are many components that go into hoisting operations which increases the chances for systems to fail.

Before the hoist takes place check to ensure proper rigging and that the rigging is laid out safely.

The loads should never be moved over personnel.

The supervisor, on the vessel, is initially in charge of the hoist and gives the crane operator the only crane signals.

As the load is being put under tension keep clear of the rigging and material.

Common mistakes are inadequate rigging and placement.

The connection of gear to the equipment is just as important as the load connection.

The crane operator does not generally have a clear view of operations that are ongoing on the deck of the vessel.

![Page 17: Shipbreaking Module 4: Heavy Equipment & Material Movement 4.1 Hoisting, Emergency, Inspect Susan Harwood Grant Number SH-17820-08-60-F-23](https://reader035.vdocument.in/reader035/viewer/2022062515/56649d0b5503460f949deb1c/html5/thumbnails/17.jpg)
Before the hoist, all personnel must be clear of the area and other equipment moved to a safe location.

Personnel can be caught between the hoist and that is why the supervisor must be accountable for all personnel.

![Page 19: Shipbreaking Module 4: Heavy Equipment & Material Movement 4.1 Hoisting, Emergency, Inspect Susan Harwood Grant Number SH-17820-08-60-F-23](https://reader035.vdocument.in/reader035/viewer/2022062515/56649d0b5503460f949deb1c/html5/thumbnails/19.jpg)
During the hoist the on deck supervisor will monitor the hoist and give directions to the crane operator.

![Page 20: Shipbreaking Module 4: Heavy Equipment & Material Movement 4.1 Hoisting, Emergency, Inspect Susan Harwood Grant Number SH-17820-08-60-F-23](https://reader035.vdocument.in/reader035/viewer/2022062515/56649d0b5503460f949deb1c/html5/thumbnails/20.jpg)
The only time personnel are allowed to approach the hoist is at the direction of the on deck supervisor.

Shock loading the hoist is prohibited and dangerous to the load, equipment, and personnel in the area.

The transfer point when the hoist is clear of the vessel is when the crane operator takes charge of the hoist.

Workers are not allowed to ride the hoist at any time during the operations.

Inspections
![Page 25: Shipbreaking Module 4: Heavy Equipment & Material Movement 4.1 Hoisting, Emergency, Inspect Susan Harwood Grant Number SH-17820-08-60-F-23](https://reader035.vdocument.in/reader035/viewer/2022062515/56649d0b5503460f949deb1c/html5/thumbnails/25.jpg)
The hoisting gear must be inspected regularly and prior to each use.

![Page 26: Shipbreaking Module 4: Heavy Equipment & Material Movement 4.1 Hoisting, Emergency, Inspect Susan Harwood Grant Number SH-17820-08-60-F-23](https://reader035.vdocument.in/reader035/viewer/2022062515/56649d0b5503460f949deb1c/html5/thumbnails/26.jpg)
The inspection has to be completed during each shift change and frequent intervals during the operation.

Defective hoisting gear must be immediately reported to the supervisor and removed from service until repaired or replaced.

Verify the safe working load of the gear for operations that will take place during the shift.

Emergency Situations

Overloading the crane and equipment is one of the most hazardous conditions.

The crane and or rigging can fail resulting in the load dropping and causing crane instability.

Tipping results when the boom is extended beyond the limits and/or load weight exceeds equipment limitations.

A crane tipping over can result in injury to the operator and loss of equipment.

The supervisor should be fully alert for any conditions that would lead to tipping or overloading.

Gear failure happens when the load exceeds the safe limits or inspection failed to find defects.

During the initial hoist the material can snag or catch resulting in overloading or straining of the gear.

Once the hoist separates from the snag it can cause a snap back of the gear causing it to swing wildly or upward rapidly.

Long reaches can have dramatic results in equipment and gear performance.

The longer the reach the less weight that can be hoisted.
