The ability to work inside and outside using a single machine is increasingly required by rental companies, as are updated models with greater performances. Euan Youdale reports
While rough terrain and slab scissors provide their own distinct benefits, there is a growing need for flexible machines that can be used throughout a project, both inside and outside.
On the issue of safety and service Mr Delgado sums up some of the key elements, but concedes there are always grey areas: “Scissor lifts already have proven safety devices, such as pothole protection, tilt alarms and level sensors with drive/lift interlock to prevent operation on unsuitable terrain. Some rental companies ask for lanyard anchor points in scissor lifts. In line with IPAF guidance we do not advise the use of harnesses in scissor lifts, but some end users do insist, so we offer them as an option.
MEC Aerial Work Platforms introduced a new 40-foot rough terrain scissor lift at the Rental Show, in Las Vegas, US in February this year. The 4069RT is available in electric and diesel power. The electric 4069 was introduced first at The Rental Show and it will be followed by a diesel variant in the second quarter of 2013.
The 4069 features four-wheel drive and fully proportional drive and lift controls, and comes standard with the MEC Quad-Trax traction control system. The 4069 can achieve 40 % gradeability. The total lift capacity of the machine is 900 pounds at full height.
Also at the Rental Show, Custom Equipment debuted three new prototype machines: the HB-P527, HB-830 and HB-1230.
The smallest model, the HB-P527, is a 5 foot platform height push-around lift. It weighs 600 pounds and can lift 500 pounds. It is 27 inches wide by 41 inches long and 64 inches tall. The unit is still in its testing stage but will be production ready in the next month.
The HB-830 and HB-1230 lifts feature 8-foot and 12-foot platform heights respectfully, with a zero turn drive systems.
The controls for the zero turn system now incorporate a full-size, multi-axis joystick with a built-in enable switch for the most precise movement of the lift, the company said.
The HB-1230 is comparable to 12-foot mast machines but provides a larger working platform with a more solid platform feel provided by the rigid scissors. Its estimated weight is 1,500 pounds and it, like its siblings, will feature a lift capacity of 500 pounds, said the company.
