A NEW TYPE of Marrel Roll-On unit incorporating underfloor tipping gear was unveiled at Amersham last week. The new equipment can handle bodies or containers to the maximum legal width and up to a maximum length of 22ft. The demonstration unit with a 30 cubic yard compaction container was flttted to a Leyland Retriever chassis. It is understood that the Purle Group is to purchase 25 of the new Marrel outfits over a period.
The container is loaded and unloaded by a hydraulic winch working at 4,000lb p.s.i. The winch is a single drum with leftand righthand spiral groove. Two steel ropes are employed and these pass round an aluminium alloy block attached to the container. The block is readily detachable.
Two sets of rollers are fitted to the container for rolling on and off the sub-frame and for ground movement. Load discharge utilizes conventional tipping practice to a maximum angle of 65 degrees. Power for both loading and tipping is by a Martel triple-ram hydraulic pump.
The Marrel Roll-On is equipped with a stabilizing roller for use when loading to prevent over-stressing of rear axle and springs. The container is secured automatically by a spring-on/hydraulic-off mechanism.
Also demonstrated last week was the Anchorpac waste compaction system which is to be produced under licence in this country by T. T. Boughton and Sons Ltd., at Amersham.
The Anchorpac system is popular in the United States and it is anticipated that the three models to be produced initially in the U.K., with capacities of 1.8, 2.9 and 3.5 Cu. yd. and at prices ranging from £2,390 to 13,500 will cover the requirements of a large section of industrial and commercial users of compaction equipment. The larger American models with capacities of 4.7 and 5.9 cu. yd. would be of particular interest to municipalities and if there is sufficient demand consideration will be given to their introduction.
The Anchorpac machines give up to 5-to1 compaction. They utilize a high speed decompression hydraulic circuit powered by electric motors—for the three models to be produced—of from 5 to 20 hp. A well engineered electronic control system is a notable feature of the equipment. It provides for automatic shut off for full load, or unattended machines, and safety retract switches are built in to cater for diagonally wedged material.
