Four wheel assemblies are fitted to the frame. Rear wheel assemblies are mounted on an articulated spreader beam to ensure an even load distribution.
1)	Electrical Motor Speed: 20 ft per min (6 m per min). The two wheels nearest the building facade are powered.
2)	Traversing frame is guided along track by guide wheels placed laterally on the wheel assemblies.
a)	Guide Track: 'L' shaped or I-beam.
b.	Lifting Mechanism: Two TWIN-TIRAK model T-1000 hoists, by the TRACTEL Group designed for TRACTEL Limited.
1)	Wire rope travels in 'S' path around two adhesion pulleys. 
2)	Overspeed Safety Brake: Engages if platform descends too fast.
3)	Disc Brake: Stops hoist during normal operation.
c.	Hydraulic System: Hydraulic ram operates the angle of the boom.
d.	Boom Luffing (series SL): The boom can be articulated on an axle fixed to the turret frame. A crossbar fixed to the boom takes the head of the hydraulic ram for operating the boom. 
e.	Cross-boom: Fixed at head of the boom enabling platform to rotate 140 degrees. 
f.	Telescopic Masts: Used for discrete parking of machine and lifting it to the operating position.
g.	Platform: 'F-type platforms' as defined by US Federal OSHA (dual-line suspension). Driven by hoists on roof unit, instead of on platform. Constructed of tubular aluminum, clad in perforated aluminum panels. Two foam rollers allow the platform to rest lightly against the facade with force of 56 lbs. (0.25 kN) and absorb swaying movements of unit. Four swivel castors fitted to base of platform make ground movement easier. Suspension stirrups can be end mounted or intermediate-type for a cantilever. Obstruction bar fitted under platform prevents collision with obstacles on descent.
1)	Typical Length: 10 ft. (3 m), however this may be increased to a maximum of 40 ft. 
2)	Typical Capacity: 525 lbs. (240 kg) max.
h.	Wire Ropes: Platform is suspended from boom by four greased galvanized steel wire ropes 5/16 in (8.4 mm) nom. dia. When the wire ropes have passed through the hoist they are wound on powered dual reelers driven by the output shaft of the hoist, via a chain and pinion system.

Signals are transmitted by 4 transducers (1 transmitter and 1 receiver each on the platform and the roofcar).
1)	A special frequency band is not required. The transmission medium is the wire rope and not radio waves.
2)	Alleviates the risks associated with radio transmission i.e. nearby systems on the same frequency, causing interference.
3)	Control Voltage: 10 V; no risk of electrocution.
4)	The telephone and LED display are provided as standard.
