Heavy mild steel welded structures using box sections where possible for hygiene and strength, and all sheet steel surfaces from stainless steel BS304 (high grade stainless steel).
Fasteners (nuts, screws, bolts, washers and lock washers) have metric threadrates and are of stainless steel, except where the application requires high tensile steel. Top
All mild steel structures are hot zinc dipped (galvanised). Please note that all galvanised surfaces and stainless steel surfaces are left self-coloured. A high build zinc phosphate primer and a polyurethane spray finish is applied in Traymaster blue, to all motors, gearboxes and other proprietary items. Top
All shafting and bearings are in inch dimensions, and all bearings are standard self aligning units grease filled and sealed, and of Dodge manufacture or equivalent. Special bearings are fitted where conditions or design parameters dictate, and all hidden bearings have remote greasing facilities. Top
All electric motors are to NEMA standards, and totally enclosed fan cooled (TEFC), and are fitted with gear reduction boxes where necessary. Aluminium frame motors will not be used and motor fan covers will be of plastic construction where possible. Gear reduction boxes are of Dodge, SEW or Brevini manufacture.
Drum motors would normally be used to drive conveyor belts, and these would be manufactured by Interroll.
Toothed belt drives (timing belts) are used to avoid lubrication and to minimise maintenance, with AS chain drives used for high torque low speed applications.
Where gear reduction boxes are fitted onto shafting and the shaft is more than 2" diameter, the gearbox is fitted with taper lock facilities, or a split bearing is fitted in board of the gearbox.
All transmission drives are guarded to the relevant Health & Safety Regulations. Top
All conveyor belting is normally Class 150 or 220, with between two and three plies of synthetic fabric polyester and nylon, with synthetic rubber (SBR) top and bottom covers, or low friction dry back, according to the application.
Belts normally have a smooth surface with hot vulcanised joints, but lugged belts with stainless steel fasteners are used where conditions or design dictate. Belts are troughed or flat with stainless steel side-guides, according to the project requirement.
Conveyors too long for transportation in one length will normally have joint vulcanisation carried out at site by a local company, paid by the customer. Top
All hydraulic systems would be to American standards, and all systems are complete with pressure relief valves, directional control valves, flow control valves, flow dividing valves and special valves, according to circuit requirements.
Suction line strainers and return line filters are fitted, hydraulic tanks have temperature and oil level indicators, and pressure gauges are provided on all major circuits.
Unless specified otherwise, we would use Eaton Char Lynn hydraulic motors, Denison pumps and directional valves, Integrated Hydraulics for general valves and controls, and filtration equipment would be by UCC-Fauver.
Hose fittings are generally threaded SAE or NPT. Top
Electrical control equipment would generally be of Telemecanique or Moeller manufacture, with relay systems for controlling processes. PLC’s are used where conditions or processes require same, and we would liase to determine a local PLC supplier/servicer.
Control consoles and all cable junction boxes are stainless steel enclosures with gasketed doors and covers, generally to NEMA 4X standards.
All electrical conductors are individually numbered at each end of each cable at all termination points, within the control consoles, junction boxes and all control devices. These cable numbers are indicated on the electrical circuit diagrams provided with the machine, to enable prompt faultfinding and simplified maintenance.
All cabling would be to U/L Standards within stainless steel conduit attached to the machines.
Emergency stop buttons are strategically positioned on the machine, dual circuits provided in each for additional safety.
Note that electrical mains supply cables and signal cables attached to buildings are not provided or fitted by us, unless specifically requested. Top
Diesel Engine Power Unit (if applicable)
Our power units are constructed within our works from proven quality components to suit the application. We would use a Perkins or Volvo engine as standard, but other engines are available to suit customers requirements, but with price adjustment.
The engine is direct coupled to a Newage International alternator, the alternator having double dipped windings fitted with anti-condensation heaters.
The engine, alternator and tinned core radiator are mounted over an eight hour duration fuel tank, and the entire assembly is contained within a weatherproof enclosure (optionally an acoustic enclosure down to 85dBa at 3 ft) fitted with stainless steel washable removable cooling air filters on the air inlet side. The air outlet side of the enclosure is louvered, and faces away from the machine operator’s station.
The enclosures are Syntec coated and finished Traymaster blue, using a two part epoxy paint.
The power unit controls and indicators are provided on the main machine control console and include - key ignition control system, oil pressure indicator, water temperature indicator, rev meter, frequency meter, voltmeter, ammeter, hours run meter, fuel tank level gauge and low oil pressure/high water temperature shut-down systems.

An operator’s manual is provided with each machine containing:
Health & Safety information;
Maintenance procedures on a weekly, monthly, quarterly, six monthly and annual basis;
Hydraulic, pneumatic and electrical circuit diagrams as applicable;
Recommended start up spare parts list;
Full machine component list giving full component description, specification, suppliers name and contact information, local agents name and contact information, and Traymaster reference numbers. Top
