The SR 1750 HE is designed to carry unit loads weighing up to 1000 kg up- and down stairs.
The accessory equipment, stair approach ramp, manoeuvring dolly and the turntable have been designed to assist the movement up to and onto the stairs and the take off from the top and journey to the final destination.

The SR 1750 HE is equipped with a hydraulic levelling platform which makes it possible to transport fragile loads in horizontal position throughout operation.

The SR 1750 HE not only reduces the number of men required for a professional move but also greatly reduces the hazards involved in a traditional stair move.

Drive:
Driving power is provided by a minimal noise, single-phase AC motor with thermal cut-out and is transmitted to the drive-axle by a built-on worm-gearbox. The worm-wheel reduction forms an effective brake if the current is interrupted for any reason.

Hydraulic levelling platform:
The hydraulic levelling platform is operated by a single-phase, low noise AC motor with thermal cut-out. A hydraulic pump is built directly onto the motor. The lowering speed of the platform can be adjusted by the descent-adjuster.

Loading winch and Ramp:
The winch is designed to fit into the lifting platform of the SR1750.  With the additional winch and ramp a load can be hand-pulled onto the SR1750 with a minimum of effort.

Control:

The robot is controlled by a low voltage (24V) manually operated 4-button switchbox connected to the stairrobot with a 2 meter remote-control cable.
 

Dolly:
A heavy duty dolly is available for handling long and bulky objects. The dolly is used to transport the (loaded) SR 1750 to and on the stairs and is used at the landing.

The dolly is constructed of square steel fittings with four heavy-duty swivel wheels for easy movements.  An extendable frame can be pulled out to increase stability while driving the SR 1750 on the dolly.  The lead-off ramp is used to connect the dolly with the stairway.
