We are looking to procure 50 units of hydraulic hoists that meet specific criteria. The hoists should be single post, semi-hydraulic vehicle lifts, designed with robust girder supports and effective sealing. We require units that operate on both air and oil, ensuring a smooth and automatic lift and drop process without any jerks. The structure should utilize an I-beam for strength and durability, and the piston must have an anti-rust chrome coating for long-lasting performance. In terms of specifications, the lifting capacity needs to be up to 4.5 tons, with a piston travel range between 150 cm and 160 cm. An automatic safety lock feature is essential to guarantee secure operation. The overall dimensions should be approximately 737 x 4877 mm, and all units must comply with the ANSI B-153-1 standard. Looking forward to your best offer on this request.
