Dimensions and mounting

WTY1 side and front outline drawing with mounting dimensions — Side and front views for the listed 1,250 kg and 1,600 kg configurations. All dimensions are in millimetres. The traction sheave diameter is 400 mm; ΦD1 identifies the hand-wheel dimension shown in the side view.

Dimension	mm	Dimension	mm	Dimension	mm
D1	181	D2	110.5	D3	290.5
D4	436	D5	122.5	D6	215
W1	380	W2	600	W3	111.5
W4	714	H1	825	H2	239
H3	290	H4	30	ΦD1	550

The side-view groove-position indications distinguish odd and even groove arrangements. Match the rope arrangement and installation clearances to the selected configuration.

Brake power and installation

The 110 V AC brake option is supplied with a controller and does not require a step-down circuit in the control cabinet.
The DC brake requires a full-wave rectified supply. Its holding voltage is 50% of its pickup voltage, so the control cabinet must provide the required voltage-reduction and switching circuit.
Confirm the AC or DC brake option when ordering. For other brake voltages, consult an engineer before selection.

Frequently Asked Questions
