Yorkshire cranes for Yugoslavia
Controlled half-ton hoist
1. A Compact platform hoist with a capacity of 500kg and hardwood deck measuring 1.5 ´ 1.6 m is claimed to take two fully laden wheel barrows. 2. Freestanding height is 6 m but further 2 m mast sections can be added to a maximum supported 46 m.
3. Chassis has a double wheel caster and stabilizing jacks.
4. The hoist drive is diesel powered from a Peter PH1, without exposed gears or chains. 5. It is controlled by a single lever which can be placed anywhere on the mast. 6. Other features include top and bottom limit trips and automatic braking.
Space saving with pivot forks
7. A useful device for saving space and, it is claimed, reducing accidents with forklift trucks is the Peg pivot forks. 8. Forks can be manually turned back from the working position 180° to over the battery box covers, on each side, but clear of all controls and the driver’s seat. 9. With forks in this retracted position the truck occupies almost half the space taken up by the ordinary forklift when in use. 10. The risk of personnel tripping over grounded forks or walking into raised forks when trucks are not in use is greatly reduced.
The rough terrain fork lift truck.
1. The rough terrain lift truck is developed as a cross between a standard industrial fork lift truck and a dumper. 2. The major points of the difference between the rough terrain and the flat-floor running industrial truck are: much higher ground clearance and larger diameter wheels, a new suspension and a number of specialized attachments which are specifically designed for the building industry. 3. In addition rough terrain machines usually have a greater degree of mast movement. 4. They also have a side tilt designed to allow the load to be lifted vertically even when the machine is not on horizontal ground.
5. A variation of the normal rough terrain lift truck is the jacklift type of a machine in which an articulated reach arm replaces the mast. 6. This arrangement gives great forward reach, over 14 ft in some cases.
7. Lift capacities range from 1 ton to 10 tons or more and lift heights from 11 ft up to 40 ft. 8. Power comes almost universally from diesels. 9. The transmission can use a gearbox, a torque converter or a hydrostatic drive through two or four wheels. 10. Rear wheel steering is usual.
Yorkshire cranes for Yugoslavia
1. All the cranes are of the latest design and full use is made of welded box girders resulting in high efficiency both in performance and appearance. 2. The heavier cranes travel on eight wheels while the smaller types are of a normal four wheel design. 3. The specifications comply with Yugoslav requirements and also satisfy German DIN regulations.
4. The main bay of the Rade - Koncar factory will be equipped with five cranes in all – two of 125-ton lifting capacity, one of 60-ton capacity and two cantilever walking jib cranes (also of box-girder construction) for loads up to 3 tons. 5. Power is provided by Crompton Parkinson electric motors mainly of slip-ring design and with power ratings of 2-70 hp. 6. All motions are plain rotor-controlled by means of Allen West control gear.
7. As there will normally be more than one crane on a track girder, the majority of the machines will be fitted with anti-collision switches to ensure utmost safety in operation.
8. Construction and installation of the cranes is being carried out in close co-operation with Yugoslav engineers both at the Keighley works and on the side.
