Thomas Armstrong Aggregates invests in sturdy design and reliable technology from Sennebogen
Gravel extraction with Sennebogen 655 duty cycle crane.
In 2016, AGD Equipment, a UK sales and service partner for Sennebogen Maschinenfabrik GmbH, delivered a Sennebogen 655 dragline excavator to Thomas Armstrong Aggregates Ltd.
Fitted with a 27-metre boom and two powerful 160 kilonewton freefall winches, the duty cycle crane is now busy digging out tons of gravel every day for the manufacture of construction materials.
With a company history that dates back over 180 years. the Thomas Armstrong Group is one of the most highly traditional companies in the British construction industry. Ever since the family business was established in 1830, it continues to progress as a market leader in numerous sectors, ranging from extraction, building materials using wooden building materials to the transport of goods.
Sand and gravel are extracted as raw material for numerous building products in the same gravel pit using dragline excavators. In 2016 the company invested in a duty cycle crane, a Sennebogen 655 HD, for this purpose. Fitted with a 27-metre long lattice boom and two 160 kilonewton freefall winches, the machine excavates tons of sand a day from the earth. A sturdy design and reliable technology were first and foremost in the crucial purchasing criteria for the Management at Armstrong.
40 seconds for an unloading cycle – thanks to the sturdy configuration of the machine.
For the dragline excavation operation, the 655 duty cycle crane was fitted with an additional slewing gear, which is hydraulically driven with 261 kW from the engine. The operator only needs 40 seconds for a 90-degree unload cycle. An optimised fairlead with rope guide in the boom base and the individually set freefall speed by potentiometer provide the best operability in operating the dragline duty cycle crane.
The comfortable Maxcab offers the operator a pleasant work environment. An extensive lighting package and cameras ensure the best overview in daily operation.
The machine is located in North-west England, in the heart of the county of Cumbria. Thanks to a close service network the competent sales and service partner, AGD Equipment, can be on site quickly if necessary for maintenance and spare parts supply.
