Coal Bowl Scrapers Caterpillar 637K
637K coal bowls are longer and higher than standard wheel tractor scraper bowls, allowing them to haul 38 m (50 yd) of low density loose coal. The bowls are designed and built to specifically deliver in coming loose coal to the stock pile and reserve stock piled coal to the feeder system.

EFFICIENCY THROUGH TECHNOLOGY
- Machine Speed Limitis designed to take the place of top gear selection. If the machine top speed needs to be limited the operator can select the top speed through the display or the top speed can be set in ET. This will allow the machine to find the correct gear that works best for the engine and transmission. Allowing the engine and transmission to select the correct gear to pull the load in most cases resulting in a lower engine load factor and lower fuel burn verses using top gear selection that required the machine to run at engine speeds at or close to high idle.
- Ground Speed Control sets the desired top speed by the operator if job site conditions or segment speed limits require a speed less than full run out. Machine Speed Limit is intended for use when top speed needs to be limited for longer durations and Ground Speed Control is intended for use when the top speed needs to be reduced for shorter segments or intermediate periods of time. The operator can set the desired top speed and the machine will find the correct gear that works best for the engine and transmission. In most cases, allowing the engine and transmission to select the correct gear to pull the load will result in a lower engine load factor and lower fuel burn verses top gear selection.
- Fuel Economy Mode is a two part feature when selected, the first part of the feature lowers the transmission shift points allowing shifting to take place at lower rpms to aid in fuel savings. The second part of the Fuel Economy Mode allows the machine, when operated at engine rpms less than full throttle, to automatically vary the power distribution between the tractor and the scraper, allowing the machine to utilize the more efficient tractor power train vs. the full time torque convertor drive scraper power train.
OPERATOR COMFORT AND CONTROL
- Advanced Cushion Hitch allows the cushion hitch to prevent end stroke by having the ability to predict end stroke events and manage the rate of dampening. Resulting in reduced hitch maintenance and improved operator ride in rough conditions.
- The K Series steering system design requires significantly less steering effort. The reduced steering effort will allow for decreased operator fatigue and a more efficient operator resulting in possible higher rates of production late in the work cycle.
- The K Series cab interior improves operator comfort and visibility. The overall interior is 21% larger than the G Series cab.
BUILT-IN SAFETY FEATURES
- Brakes have been changed from an air actuated drum shoe brake to a hydraulic actuated tractor wet disc brake and a scraper dry caliper.
- Tire Spin Reduction allows the machine to control the slip of the tractor tires only. When Tire Spin Reduction is selected the machine will control wheel spin on the tractor by keeping the slip in the optimal range for loading by adjusting engine rpms with no additional operator input.
- Engine Over Speed Protection - In the event of an engine over speed situation, the compression brake or brakes will automatically engage with no operator input. The machine determines the over speed condition based on rate of acceleration and applies compression brakes automatically.
- Differential Lock Engagement Protection allows the machine to prevent the operator from engaging the differential lock when damage could occur.
- Coal bowl scrapers are effective in compacting coal, which reduces the risk of spontaneous combustion of coal in the stockpile by eliminating the air spaces.
MAXIMIZE PERFORMANCE
- Coal Bowls are longer and higher than standard scraper bowls, which allows Wheel Tractor-Scrapers to haul 38 m (50 yd) of low density loose coal. The bowls are designed and built to specifically deliver in coming loose coal to the stock pile and reserve stock piled coal to the feeder system.
- Sequence Assist (optional) uses cylinder position sensors to automate bowl, apron and further implement controls throughout the four core work cycles: Dig, Haul, Unload and Return. When utilized this can reduce up to 14 individual operator commands per cycle. Sequence Assist simplifies control over the implements, reduces joystick usage, automatically controls cushion hitch, transmission hold and ejector.
SAVE ON MAINTENANCE TIME
- The fuel, water and engine oil are relocated at ground level on the right hand side of the machine for easy access.
- In cold weather conditions the machine will use the Auto Stall feature to help warm up the transmission oil faster resulting in the machine shifting out of torque converter drive (2nd gear) faster than on previous models.
