Update on this new series.
All lifts claiming to be “ALI Certified" have to be re-tested to meet
the latest ANSI/ALI ALCTV Standard that was officially released by ALI and ANSI last fall. The effective date to comply with the new standard is July, 2018. We currently have over 30 models of lifts undergoing testing including this new GP-7 series. The two shorter models (GP-7LC and GP-7LCS) will be released as ALI Certified models just as the current (taller) GP-7 model is.
What does ALI Certification mean to you as a lift buyer? Below is just a fraction of what is involved.
Static Load Test:
The lift is raised to an elevation that induces the greatest stress on the lift. The automatic safeties are then disengaged. A certified weight or payload that is 150% of the rated capacity of the lift is then placed on the lift with the arms positioned to produce the greatest stress on the lift and/or arms. The lift must sustain the load for five minutes with no measureable deformation of materials or visible signs of wear, fracture of materials, failure of welded components or other connections.
Locking Device Load Test:
The lift is loaded and tested using the same procedures described in the Static Load Test. The Static Load is then supported by the locking device. The locking device must sustain the load for five (5) minutes with no deformation of materials or visible signs of wear, no fracture of the mechanical locking device or the lift structure to which it is attached.
Automatic Arm Restraint Test:
The arm restraint is tested on the lift representing the longest arm available for the lift, and positioned within the normal range of arm deployment for lifting. The arm restraint is tested by applying a 150-pound load in the plane of the arm's axis of extension. The arm restraint must sustain the test load for five (5) minutes with no deformation of materials or visible signs of wear, no fracture of the arm restraint or the lift structure to which it is attached.
Fastening Device Strength Test:
Screws, pins, bolts, keys and other fastening devices located in the load path of the lift are subjected to tensile and/or shear loads of four times the maximum load applied to the fastening device with the lift loaded to maximum rated capacity. Fastening devices must not fracture or deform to the point of releasing the retained lift components.
Hydrostatic / Hose Strength Test:
Based on the maximum pressures measured during the Operation Test, the hydraulic system is tested as noted below and held for one (1) minute. Three times maximum operating pressure - Piping fittings, valve bodies, cylinders, pump housing. Four times maximum operating pressure - Rigid tubing, flexible tubing, hoses. There must be no rupture of tested components, excluding seals and gaskets.
Lowering Speed Test:
The average lowering speed of the lift loaded to maximum capacity is tested to not exceed twenty feet per minute (20 FPM) with or without a hydraulic line rupture or simulated break.
*The above testing procedures do not identify all requirements prescribed by ANSI/ALI-ALCTV.
I will update this thread as things develop but I suspect the (now delayed) release of the two shorter models (GP-7LC and GP-7LCS) will be May 2018.
