Northern Ireland machinery manufacturer SlurryKat has designed a special combination trailer specific initially for the New Zealand market.

High demand from customers in the country for a trailer that could work both as a dump trailer and a silage trailer, led to the New Zealand SlurryKat agent, Brownrigg Agri Gear, requesting the new design.
SlurryKat CEO and principle design engineer Garth Cairns was only too willing to take up the challenge and create the new trailer.
Garth said: “We have developed this special Premium Plus range of combination silage dump trailers. The new SDT trailers incorporate our 22 tonne Hardox half-pipe Premium Plus dump trailer plus an additional silage kit including a hydraulic silage door,” he said.
"In fact, the dump trailer used in the SDT range is a completely new design from the ground up with a new chassis and a new pendulum bogie system, as requested by the New Zealand agent for the market".
It is also available with multi leaf sprung suspension if required. The trailer has a single tipping cylinder which has 52 tonnes of force in the first stage which gives it superior tipping power even if the trailer is overloaded.
The chassis and all the main components, except the body, are made from S355 high tensile steel. The body itself is manufactured from Hardox S700 material which is a very hard and durable material.
Garth added: “Using this high-quality material means we can make the trailer lighter by using 5mm thick material on the body whilst still achieving the high structural strength the trailer requires.
Looking at the body itself, the trailer is a half-pipe dump trailer but with the added features of a rear dropping door. All the half-pipe trailers on the market have an upward and over type hydraulic door.
This one has a dropping door at the bottom which means it is square at the back. It goes from a half-pipe formation to a full width square rear door which is thought to be the only one on the market with this design,” he said.
"The trailer gets significantly wider at the rear which greatly improves discharge speed without leaving material in the body.
The silage kit is designed to be removed in one complete piece including the door leaving the dump trailer below to change fast and efficiently between applications".
When the kit is added the dump trailer door drops flat to allow a totally flat floor for easy material flow.
The silage kit is designed with a forward sloping dropped front panel which is a huge aid when opening up silage fields and blowing grass over the tractor hauling the trailer.
When the silage kit is added to the dump trailer the combined unit has a capacity of 34 cubic metres of silage.
The trailers are fitted with 710/40 R22.5 BKT Tires, and come complete with a hydraulic jack. All the trailers are finished with the two-pack paint which has a five-year guarantee as standard.
Demand in New Zealand is strong for the new trailer and already SlurryKat has 24 of the new machines in preparation for shipping.
