The left hand joystick used to select travel direction and to provide infinite speed control up to a maximum of 9.7 km/h. Side mounted buttons allow manual selection of any of the 10 speed increments to suit particular operating requirements. To hold the 1650L stationary when the engine is switched off, the machine comes as standard with a heavy-duty, spring-applied hydraulic release parking brake. Low-effort blade hydraulics The right hand joystick controls all the motions of the PAT (power, angle and tilt) blade by means of logical forward/reverse, left/right and twisting movements. The low-effort hydraulics aid precise blade adjustment on the move to maximise load retention and carry out efficient dozing to the required grades. A separate right hand lever operates the optional ripper (not fitted on the Monthyon demonstration machine) that can be equipped with three or five teeth. When sitting on the comfortable suspension seat in the air conditioned ROPS The use of a narrow instrumentation panel and a tapered bonnet view provides a clear view of the front of the tracks and both sides of the 3.98m wide, 3.2m³ capacity PAT blade. The test dozer had the 2.13m gauge LGP (low ground pressure) tracks with 864mm wide shoes which maximise flotation when used on soft ground. Other track options are the 1.87m gauge XLT (extra long track) with 610mm track shoes for precision grading and the 2.13m gauge WT (wide track) with 864mm shoes – most suitable when extra stability and a wider blade are needed for finish grading or slope work. Sealed and lubricated track pins Ground pressure varies from the XLT at 42.8kPa, to the WT at 38.7kPa and the LGP undercarriage, which puts down just 31.9kPa. All models use the Case Lubricated Track system with its sealed and lubricated pins. An optional Case Extended Life Track, with a second hardened bushing, is available for abrasive soil conditions. All the three LGP, XLT and WT configurations utilise Case Lubricated Track with sealed and lubricated pins as standard. An option for sustained use on abrasive ground is the more durable Case Extended Life Track (CELT). Daily service checks can be carried out from ground level and there are quick-disconnect diagnostic test points to assist any necessary troubleshooting. Mechanics will appreciate the side tilting operator platform and cab. It takes less than ten minutes to ‘open up’ the machine in this way to obtain really good access to its power train, electrical and hydraulic systems. The 1650L and 1150K were launched in the USA at the ConExpo exhibition in 2008. Now their availability in Europe will provide Case and its dealers with more sales opportunities. Time will tell whether the other Case bulldozers are also offered in Europe. [CP&E] Case Construction CP&E Contractors Plant & Equipment Vol 1 No 6
CP&E Contractors Plant & Equipment Vol 1 No 6 Nick Johnson highlights the latest compact telehandler from the French maker Manitou – the Maniscopic MT625T which has a maximum lift height of 5.85m. New Manitou makes its mark Amongst all the new machinery being launched at the Bauma exhibition in April was the latest small telescopic handler from Manitou. Designated the Maniscopic MT625T, this compact machine slots into the increasingly popular market segment for handlers which are less than two meters wide and high. The MT625T is actually 1.82m wide and 1.92m high (with its magnetic flashing beacon removed) so that it can access low headroom areas and operate in confined spaces. The machine is a little bigger than the long established Buggiscopic but it scores over its smaller brother by offering greater lift height and a more roomy cab. Equipped with a two section telescopic boom, the MT625T can raise 2000kg up to its maximum lift height of 5.85m – to enable a 3rd tier lift onto scaffolds. Maximum forward reach is 3.4m at which an 800kg load can be carried. Usefully a 1.2 tonne pallet can be can be picked up 2.5m in front of the front wheels. Side mounted Kubota engine The new design, low boom MT625T telehandler has a side mounted 55.4kW (75hp) Kubota V3307-D1-T-E3B Euro 3A emissions compliant engine and a hydrostatic transmission. There are two speed ranges – up to 7 km/h for site operation and a maximum of 25 km/h on the highway. An ergonomically shaped JSM multifunction joystick allows the MT625T operator to conveniently select travel direction and control all the boom and carriage motions with his right hand whilst keeping his left hand on the steering wheel. Roller controls on the JSM joysticks are sensibly used to facilitate boom extension / retraction and auxiliary equipment operation. To aid smooth operation, all the telescopic boom functions are proportional and independent. The low slung, side mounted ROPS/FOPS cab is easy to enter and inside the operator finds a quiet (76db(A)) environment with an adjustable seat. The machine features a simple 10 second start-up sequence, a safe load indicator (with a vertical display of green, amber and red LEDs) and a switch to neutralise the JSM joystick to prevent involuntary movement of the boom or carriage during road travel. Safe load indicator display There is an emergency engine stop button located next to the JSM joystick and the machine has an easy-to-read instrument panel. As well as housing the safe load indicator display, this panel includes an hour meter and fuel gauge as well as being able to show when the next service is due and indicating diagnostic codes for fault finding and servicing. The MT625T is only 1.92m high so that it can access low headroom areas and operate in confined spaces. The new MT625T compact telescopic handler was launched by Manitou at the Bauma exhibition in April 2010. Page 21
