Condition: new, Year of construction: 2026, functionality: fully functional, 600 HD available immediately Serialnumber 965 Special price from our stock 06188 Landsberg, Germany The 600HD alligator shear is a fast and strong metal cutting shear with an extended hold down clamp, making it ideal for every cutting and cleaning task whether cable, plastic sections or window frames. Its cutting capacity is up to 63mm, 2″ inch mild steel round bar. Hnedpfx Ahoib Ircj Rjn The 600HD alligator shear is probably best known for dealing with car radiators. It was designed and built following requests from customers who were looking for a shear with a longer blade to cut larger items such as car radiators which it cuts through in one pass. The automatic hold down clamp holds material in place during the cutting cycle and prevents kick back which speeds up processing and improves operator safety. As with all McIntyre shears, opening and closing the jaws is controlled from a moveable foot pedal. As soon as the foot pedal is released, the cutting blades return to the open position. However, a continuous cutting action can be achieved by keeping foot pressure on the pedal. The 600HD can be supplied with an electric motor or with a 2-cylinder diesel engine.

Condition: new, Year of construction: 2025, JMC 600 GT on stock. Rental and financing possible The 600 GT features a blade guard system which gives good visibility to the operator and Hnedsid Ipcjpfx Ah Rsn acts as a hold down to prevent material kick back. The machine is foot pedal operated and the jaws return to the open position once the foot pedal is released to increase safety. Wheels are fitted as standard, and forklift points have been included on the body of the machine to ensure that it can be safely lifted both within the yard and during transportation. Ideal for larger items such as car radiators which can be handled in just one pass. The 407/500/600GT can also be adapted to process catalytic converters. JMC catalytic converter shears have been purpose built to recover the valuable dust containing precious metals found in catalytic converters in ELV (end-of-life) vehicles. The shears are sufficiently versatile to be used anywhere in your yard. The catalytic converter is placed in the jaws which are controlled by a foot pedal, and cut open Once cut, the pinched end of the converter can be re-opened using the side bracket attached to the top jaw, allowing the contents to be poured out. All JMC Cat Shears can be supplied with dedicated extraction and filtration systems to remove additional dust because this may also contain precious metals. So you can be sure that you will maximise the return from your catalytic converters. Shears in the range include the 407 Cat which has a 407mm, 16″ blade, the 500 Cat which has a 508mm, 20″ blade and the 600Cat which is equipped with a 608mm, 24″ blade.
