S.I.T.C. of Static Compactor Capacity -100 MT per day The static compactor should be designed to receive garbage from Mini Tippers and compact the same into Roll-on-Roll-off containers which are then picked up by Hook Loaders and transported to respective Site. The static compactor would be hydraulically operated bin cart loading mechanism which receives the garbage from mini tippers and load the garbage into the charge box of the Static Compactor. The features of Static compactor shall be as per followings:- • Horizontal compaction machine with tipcart mechanism • Hopper • Guillotine system • Hydraulic Clamping Claw • Drainage System for leachate • Hydraulic Power Pack • PLC based Electronic Controls. • Charge Box Volume of 3 CU.M. maximum and shall be fitted with 11 KW Electric Motor. • Charge Hopper • Hydraulic Compaction Container Coupling • Hydraulic Vertical Locking Mechanism • Hydraulically operated Bin Cart loading mechanism • Guide plates for Roll-on Roll-off Containers - 2 sets • Compactor should be in heavy duty design with extra strong sheet thickness with horizontally operating straight single cylinder system. • Hydraulic System shall be with regenerative control for faster cycle time • Should have fail safe hydraulic ram control without limit switches, press plate will be in low maintenance plastic guides • Should have container 75% full warning system • Should be equipped with extra pressure boost and automatically plate positioning for closure operation • Control Panel shall be with main switch, emergency stop button, function button and function lights

• All hydraulic functions should be controlled via a central, maintenance free valve Hydraulic Unit with oil filter and oil level gauge. o Charge box volume approx.-3M3 o Compaction cycle time- 42 Sec. o Theoretical volumetric capacity- 257 M3/Hr o Normal Pressure- 26 Mpa o Max. Pressure – 30 MPA o Normal Compaction Force- 320 kN o Max Compaction Force- 370 kN o Density- 0.75-0.80 Tonne/M3 o Motor Power – minimum 15 kW o Power Supply -440+5% V o Distance into container-500 mm • The Hydraulic Container Coupling should be of a pair of hydraulically operated Hook with lever which pulls, align and attaches the container to the compactor unit before loading the garbage into the container. After the container should be loaded the Hydraulic Coupling releases the container which would be detached from the compactor before lifting by the Hook Loader. • The Container opening should be provided with a sliding steel gate. The Gate would be lifted by a hydraulic vertical mechanism before loading the garbage into the container.• After the container is loaded, the hydraulic vertical mechanism would push the container sliding gate downward and closes the opening. The complete Operation would be controlled by means of push buttons • Oil Cooler should be integrated completely to Hydraulic Power Pack. • Each compactor unit should be provided with mild steel Bin Cart having a garbage holding capacity of 2.5 T (3 Cum.) and would be designed to receive garbage from Mini-Tippers and load into the receiving hopper of the static compactor. The Bin cart loading device can be Rear loading, left or right hand loading as may decided during finalization of order.
