Model	Travel	Capacity	MIN	MAX	Platform Size	Base Frame	Ends	Sides	Up Speed (F.P.M.)	Motor Std. HP	Cylinders	Ship Weight
SLD-300-812	60"	30,000 lbs	24"	84"	96" x 144"	88" x 112"	24,000 lbs	21,000 lbs	5	7.5 HP	3	11,250 lbs

In 48" travel, other platform sizes are available. Listed ship weights are for standard platforms only. When voltage is 230V/1PH/60Hz lift speeds will be reduced by 33%. Note: Where available power supply is 208V/3PH booster transformers are required for 240V/3PH at motor, see options. Roller shades, accordion skirting and electrical tape switches will require a minimum lowered height of 10". Power requirements depend upon frequency and type of operation and require specific selection. 8'0" wide units require shipment via flatbed.

Features

Sealed ram-type, full oil displacement hydraulic cylinders with hard chrome plated and polished stress-proof steel rams and polyurethane seals. Positive internal stops
Safety velocity fuse at base of each cylinder to prevent descent in the event of loss of hydraulic pressure
NEMA 4, 13 (water tight, oil tight and dust tight) adjustable upper travel limit switch automatically shuts off the motor and pump at the raised-height setting
Four secondary mechanical upper travel back-up stops, 2 mounted on platform understructure and 2 mounted on base, restrict the scissor arms from moving beyond the preset travel
Axles and shafts are stressproof shafting, hard chrome plated and polished, retained with a positive-locking screw ring system and equipped with lifetime lubricated bearings
All axle and roller bearings are PTFE lined, composite type and have the qualities of good wear resistance and heat conductivity, high strength, low thermal resistance and low friction
Hydraulic hose, SAE 100 R2AT, double wire braid from cylinders to universal connection on base frame. Hose from lift to power unit is not included
Aluminum valve block manifold contains check valve, relief valve, pressure-compensated flow control valve and solenoid valve. The solenoid valve includes a filter screen
NEMA-12 prewired control box (dust/drip-tight industrial type) with liquid-tight electrical connectors. Control box contains magnetic starter, control transformer, thermal overload and fuses, mounted on the oil reservoir
