Engineered for Hazardous Chemical Zones & Multi-Floor Vertical Dispatch
SRE’s Flameproof Dual-Mast 4-Ton Hydraulic Goods Lift provides safe multi-floor material transfer in Zone 1 & 2 explosive environments. Engineered with PESO-certified explosion-proof motors, dual-mast structural steel guides, and safety landing interlocks, it safely bridges heights up to 18 meters.
Key Engineering Challenges & Plant Risks
- Explosive solvent vapor presence requiring ATEX/PESO flameproof electricals and Ex-d enclosures across all floors.
- 4-Stop vertical travel (16 meters) with high leveling accuracy for smooth pallet truck drive-in without floor steps.
- Fail-safe anti-fall arrestor mechanisms and interlocked flameproof hoistway landing gates to prevent accidental door opening during transit.
Delivered SRE Engineering Solution
- Heavy dual-mast cold-rolled guide columns with precision machined crossheads ensuring zero platform tilt under eccentric loading.
- Flameproof powerpack with explosion-proof motor, intrinsically safe push button stations, and armored cabling.
- Dual wire-rope safety arrestor cams and pilot-operated hose burst check valves preventing sudden platform descent.
- Electromechanical interlocks on all landing hoistway gates preventing operation unless fully closed and locked.
Operational Outcome & Safety Compliance
Successfully commissioned for multi-floor chemical and API pharmaceutical manufacturing plants in Ankleshwar, fully certified with 125% proof load testing and statutory factory inspector approvals.
Frequently Asked Questions: Flameproof 4-Ton Goods Lift
Q1. Which hazardous area classifications is this goods lift certified for?
Equipped with PESO/CIMFR-certified explosion-proof motors and flameproof Ex-d push button stations certified for Zone 1 and Zone 2 hazardous gas and solvent vapor environments (Gas Groups IIA, IIB, and IIC).
Q2. What safety interlocks prevent the lift from operating with open landing gates?
Electromechanical door interlocks ensure the platform cannot move unless all landing gates are completely closed and locked. Opening a gate during transit halts the lift immediately.
Q3. What are the maximum travel height and payload capacities available?
SRE manufactures dual-mast goods lifts for payload capacities from 1,000 kg up to 10,000 kg with vertical travel heights reaching up to 18 meters (Ground + 3 floors).
Q4. Does SRE provide turnkey erection and statutory load testing?
Yes. SRE provides end-to-end site survey, 3D CAD shaft layout, structural erection, on-site 125% overload proof testing, and nationwide commissioning.
