Product details
1. Product Introduction
(1) Product Overview
A jack is a hydraulic/mechanical lifting device specialized in lifting heavy objects, equipment installation, vehicle maintenance, and other scenarios. Adopting high-strength alloy materials and precision hydraulic technology, it has the characteristics of strong load-bearing capacity, easy operation, safety and reliability, and is widely used in fields such as automobile maintenance, construction, industrial equipment maintenance, emergency rescue, etc.
(2) Core advantages
Super strong load-bearing capacity - rated load of 1-200 tons, special models can reach up to 500 tons
Efficient lifting - hydraulic type single stroke can reach 200mm, mechanical type fine adjustment accuracy is 0.1mm
Safety protection - built-in overload protection valve, equipped with explosion-proof hydraulic pipe (hydraulic type)
Multi scenario applicability - the base can rotate 360 ° to adapt to uneven ground
Durable design - surface chrome plated anti rust, IP54 protection level
(3) Typical applications
-Car maintenance: lifting and replacing tires for cars/trucks
-Construction: Steel structure installation, bridge jacking
-Industrial field: Heavy equipment maintenance positioning
-Emergency rescue: The accident vehicle was lifted and rescued
-Railway maintenance: track adjustment operation
