The Pq500-TR

The PQ500-TR (Tower Version) Ascender is a powered, yet lightweight personal lifting device that scales vertical surfaces quickly, safely and inexpensively using standard climbing equipment.   This unit is equipped with a wired as well as a wireless remote control  allowing the unit to be used in areas where radar, EMF or other elements may interfere with standard wireless operations. 

Operational Features

  • Equipped with a separate Wired Remote for use in high-interference areas (6' cable)
  • Lifts 500 pounds/227 kg; gross load 550 lbs (250 kg)--includes PQ 500 and battery pack.
  • Weight: 28 pounds (13 kg) w/battery 40 pounds (18kg)
  • Detached Battery (Ni-MH-44 VDC ); 12 lbs (5.4kg)
  • Can operate manually or by wireless remote control
  • Lifting speed: 0.7 ft/sec (.22m/sec) 42 ft/min (13m/min)
  • Powered descent speed: up to 1 ft (.3m/sec) 
  • Designed for use by one person, for work positioning and/or moving tools and materials
  • Easily carries 2 people for rescue applications
  • Meets CE, EN, OSHA, CSA and other applicable safety requirements
  • Can be used with a variety of lifting chairs and platforms
  • Operating Temperature Range: -4˚ F to 122˚F (-20˚ C to +50˚ C)
  • Approx. climb per battery 500'-700' per charge (152-213m)
  • Charge time: 2-3 hrs. (dependent on remaining charge state)
  • Approx. 800 charge/discharge cycles
  • Can be operated with gloves and protective clothing
  • May be used with a spreader bar and work seat or boson's chair

Rope

  • Use with 1/2-in (12.7 mm)  static (low stretch) kernmantle  rope (PMI &  New England brand ropes recommended)
  • Can be configured to fit rope sizes 8mm-12.7mm

advantages

  • Using both batteries simultaneously increases climbing time with the use of a spreader bar (PQ spreader bar recommended)
  • Clean and silent
  • Can be used in oily/dirty environments without affecting performance (clean rope periodically during use in these areas); No negative affect from corrosive environments, e.g. salt water or spray (clean after use)
  • Compatible with standard climbing gear
  • A short setup time: quick, safe and less expensive than traditional lifts
  • Can also be used in places which cannot be reached with traditional lifts or powered platforms
  • Can be operated with gloves and protective clothing
  • Lightweight alternative for wire winches:  perfect for lifting materials and equipment
  • Safer working methods: less risk for falls; less fatigue on personnel
  • Improved ergonomics:  eliminates climbs for the user
  • Can be used in association with conventional rope tools such as pulleys to increase lifting capability 
  • Can be operated in high interference areas

Safety Features

  • Tested to a safety factor of 4x the rated load
  • Will not slip on rope @ 2x the rated load
  • Temperature sensor shuts unit down in event of motor temperature exceeding 85°C
  • Interlock switch on cover ensures that unit will not operate if rope handler cover is not properly closed
  • Remote control overrides local control
  • Rope cannot be removed from ascender when it is under a load 
  • Auto-braking in hands-off position provides for both locked-off and emergency or panic lockoff. No force need be applied for panic lockoff
  • Load limiter: prevents lifting of load in excess of 750 lbs (340 kg)  
  • Static Load/Stationary holding capacity: 1,100 lbs (499kg)
  • Dynamic load capacity: 3,300 lbs (1,497 kg) —Must survive and hold the rated load after a 0.6 meter drop test in accordance with CSA Z-259 or ANSI-Z359-4
  • Forward reverse control
  • Palm interlock must be engaged to start unit
  • Low voltage sensor detects low battery voltage and shuts unit down.  PQ500 level is 33 VDC.  In the event the motor shuts down, the manual brake release allows descent mode only.
  • No pinch points
  • No sharp edges, points, etc., capable of puncturing or cutting the skin
  • Accessible surface temperature does not exceed 65° C
  • Rotating parts protection
  • Designed to withstand 4' drop
  • No electrical shock hazard
  • Battery cable is 6' (1.8 m) with a threaded connector on both ends.  The cable connectors are such that it is impossible to connect the cable backwards
