Tippler Machines Overview

Machines used by private siding owners to unload BOX 'N' wagons loaded with coal.

One type of tippler machine used for unloading wagons.

Another type of tippler machine used for unloading wagons.

Tipplers must be designed to avoid damaging wagons during unloading.

Pressure needed to hold wagons securely on rails without deforming them.

Adjustments in tippler design to accommodate wagon variations in construction.

Longitudinal beam used to support tippled wagons; must be articulated to accommodate varying wagon styles; contact length 1950 mm, height 1000 to 2950 mm.

Longitudinal beam supporting tippled wagons. Must be adjustable for different wagon heights.

Wagons under 2950mm in height use special slots in the side support beam.

Side support beam and wagon side stanchions contact directly, no padding.

Side support beam can move hydraulically, forward/backward, without pressure on the wagon.

Measures hydraulic pressure on the side support beam (for safety).

Design features that stop wagons from moving too far forward or backward.

Tippler design must securely hold wagons in all operating positions.

Mechanism for keeping the tippler securely in any position even if the power fails.

A safety feature restricting the maximum angle of the tippler to avoid damage or spillage.

Mechanical or electrical devices ensure that all conditions for wagon tipping are coordinated.

A device prevents empty wagons from releasing until the tippler returns to its original position.

A device prevents a wagon not on the schedule from entering the tippler.

Working spaces must not have sharp edges or corners to prevent injury.

Parts projecting into working spaces should be kept as small as possible.

Frequently used lubrication points must be accessible without removing guards.

Equipment should be designed to make maintenance and cleaning easier.

Integrated controls for wagon positioning, holding, and tipping are needed.

A positive system is needed to center the wagon on the tippler table.

The drive unit for the side arm charger must be of a positive type (e.g., rack and pinion) to prevent sudden movements.

Clamp pad thickness must be at least 50mm to ensure proper support and prevent damage.

The clamping mechanism must move smoothly to avoid jerking the wagons and prevent damage.

All wagons potentially tipping must have indicators on the tippler table to ensure correct placement for optimal clamping.

The maximum force exerted by the top clamps should not exceed 1.5 tonnes per clamp pad to safeguard wagon integrity.

Mechanisms to release bogie springs should be present on the tippler locks.

Wheel grippers should be made of a soft material to prevent wheel damage during tipping.

Wheel grippers should not have serrations on their holding faces.

Mandatory devices fitted on tippler tracks to prevent wagon movement.

Wheel chock design should avoid contacting the wheel flange while blocking the wheel.

Chock shape should consider wheel inclination for proper wheel contact.

Six-monthly inspection of tipplers by designated personnel and siding owner representative.

Steel work on end frames should be inspected for damage.

Drive gear inspection should focus on matching rack and pinion teeth and wear.

Top hydraulic clamp pad level should be checked for proper seating.

Ensure tippling operation is smooth and without jerks during rotation.

Two types of tipplers exist: side discharge and rotary.

Tippler design must avoid damaging wagons during unloading.

Pressure needed to securely hold wagons without deforming them.

The side support beam must be as long as the longest wagon to be tippled and continuous.

Side support must adjust to accommodate varied wagon shapes.

Side supports must extend from 1000mm to 2950mm from the rail level, for full contact with the side of the wagon.

Side support contact width must be at least 1950 mm for proper wagon support.

Wagons under 2950mm in height require special slots in the side support beam.

The side support beam and wagon side stanchions contact directly, without any rubber pads or other alternatives.

The side support beam moves hydraulically forward and backward to accommodate wagons without applying pressure on the wagon side wall.

Measures the hydraulic pressure on the side support beam for safe operation.

The tippler design includes features to prevent wagons from moving too far forward or backward.

The tippler must securely hold wagons in all operating positions.

A safety feature which restricts the maximum tippling angle of the tippler to prevent damage or spillage.

Using mechanical or electrical devices to ensure all conditions necessary for wagon tipping are synchronized.

A safety measure preventing empty wagons from being released until the tippler is in its original position.

A device to prevent wagons not on the schedule from entering the tippler.

Working areas must be free of sharp edges and corners to prevent injury.

Parts extending into working spaces should be as small as possible.

Frequently used lubrication points should be accessible without removing guards.

Equipment should be designed to simplify maintenance and cleaning procedures.

Integrated controls for wagon positioning, holding, and tipping are required.

A positive system to centralize the wagon on the tippler table.

The drive unit for the side arm charger must use a positive system (e.g., rack and pinion) to prevent sudden movements.

Wheel grippers should be made of a soft material to prevent wheel damage during tipping.

Wheel grippers should not have serrations on their holding faces.

Mandatory devices fitted on tippler tracks to prevent wagon movement.

Wheel chock design should avoid contacting the wheel flange while blocking the wheel.

Chock shape should consider wheel inclination for proper wheel contact.

Six-monthly inspection of tipplers by designated personnel and siding owner representative.

Steel work on end frames should be inspected for damage.

Drive gear inspection should focus on matching rack and pinion teeth and wear.

Top hydraulic clamp pad level should be checked for proper seating.

Ensure tippling operation is smooth and without jerks during rotation.

The minimum thickness of the clamp pad should be 50mm for proper support and preventing damage.

The clamping mechanism must move smoothly to avoid jerking wagons and preventing damage during operation.

All wagons which could potentially be tippled, must have indicators on the tippler table to ensure proper placement for clamping.

The maximum force exerted by the top clamps should not exceed 1.5 tonnes per clamp pad to prevent wagon damage.

The tippler must have mechanisms to release bogie springs on the top clamp locks to allow for proper release.
