Construction industry, as expectn embracing 44-tonners with enthusiasm weights uplift has increased capacities I a typical 54yd3 (41.3m3) trailer at 38 tel COW to 61-64 yd3 (452-490) at 44 tonne TIPPer operators are having to inve: remain competitive, says Angus Spo: general manager. tippers, at Gen Trailers, and running costs per tonne of load at 44 tonnes are substantially Ii than they are in a 32 or 38-tonne 8x4, the same If not better manoeuvrability.
Short wheelbase
Most tipping trailers have a short wl base, which makes meeting turning c requirements more difficult. Tippers go ally need to have 10.5-11m bodies to meet requirements, so check if you are plan to uprate existing trailers.
Trailer designs must allow a relat long overhang of body in front of the kin or the operator risks putting toe I weight through the drive axles while o loading the trailer bogie. "We believe best solution is to have a recessed mounting inside the body front bulkhc says Spooner. "Other solutions potent involve extra weight."
DC has developed a 44-tense design that. accommodate a lifting axle and still I the turning-circle rules. The trailer a 7.45m wheelbase and a 10.35m body a flat, not sloping, front bulkhead, and uter-cover ram, not a 'dog-house ram. leightlifter has selected an 8.15m wheel: with a 'dog-housed' ram for its 44e tipping trailers to ensure that suffi
t load is imposed on the king pin. It 's a choice of sloping and straight hodwith the sloping body design preferred ticky loads.
parators carrying light aggregates might blow away in the wind must r the load to comply with regulations. In interests of simplicity, manufacturers illy recommend a front-to-back lianically operated cover system, High products loaded so the apex is ay than the body side walls often have over covers that are operated from to side, passing over a centre spine.
ight bodies for 6x2 and 6x4 operations generally smooth or plank-sided, with walls up to 1.22m high. Ribbed bodies er extra strength and sidewalls can be s 198m high, which increases cubic laity but reduce payload allowance.
