Complete Gantry System Setup and Adjustment Points

2m Span Labelled

SELS offer our mobile lightweight aluminium fall arrest man riding gantry system with independent fall arrest and manual rescue winch. It is designed for maximum portability so that it can be adjusted in size to suit our customers working environment; both height, width and optional equipment and accessories.

The legs are also adjustable meaning that the gantry can be easily adjusted in all corners so that it can be made level in rough terrain; we also offer with a screw jack system that allows very fine adjustment of the gantry legs. For safety reasons we do not fit Castor's as used on lifting systems; the gantry is so light enough to move with out the need for castors.

Fully certified with EC Declaration of Conformity and comprehensive Operation and User Manual / spare parts lists. Every system is assembled before dispatch and load tested - including individual component parts!

Modular / KnockDown

The modular design of the gantry means that it is quickly assembled with only hand tools required.  The modular or knock-down design means that the rescue gantry can be easily disassembled for transportation.

Super-seeding the requirements of EN795, we supply our Man Gantry only as a  bespoke system; complete with specialist fall arrest / man-riding and rescue equipment for suspended working at height and restraint / fall arrest systems for the operator and rescuer. The important and unique feature is that we supply all systems designed to meet  our customers specific height safety requirements. 

Gantry Design Features

The general design of the Aluminium man-riding gantry system offers more space for manoeuvrability of the worker, operator and rescuer than you would get with a tripod system. The gantry can be fitted with anchorage points to suit your individual needs though as standard is fitted with 2 x overhead fall arrest / restraint anchorage points / eyes for use by the hoist operator and potentially a rescuers. The electric or pneumatic man-riding hoist is mounted one of the vertical 'A' side sections and the fall arrest / rescue winch to the other; the wire ropes then pass through a pulley / bracket system ending-up in the desired position that the worker will descend. Fitting the hoists to the gantry legs means that we avoid the necessity to work at height as would otherwise be needed if the unit was to be mounted to the overhead lifting beam. Virtually no manual handing is needed to install the hoists as we utilise lifting points installed on the overhead beam and the hoist along with a lever hoist to lift the hoist onto its mounting bracket.

Additional Information - Options!

All gantries are customized to our customers requirements with adjustable height and width. Standard maximum width is 2 metre and height adjustable from 1995mm to 3220mm (under beam) - special dimensions are available on request! All systems are supplied with specialist height safety equipment to provide safe operations while working at height.Working height with a spring reeling drum is possible at heights of up to 60 metre, we use a separate (not attached)  cable reeler when greater working heights are needed. Manual fall arrest inertia reels with integrated retrievers are supplied to a maximum working height of 40 metres; greater heights / depths use an alternative fall arrest / rescue system (not shown here).

The arrangement illustrated shows a a 110v electric powered man-riding hoist for suspended man access, also fitted is a fall arrest inertia reel; this provides fall arrest protection (a back-up) in the event of a failure to the electric hoist, the inbuilt hand operated winch provides a means of rescue in the event of a failure to the primary hoist (Mechanical, electrical or power failure).

Contact our sales team for a quotation and for advise on equipment to suit your your needs.

The Electric / Pneumatic Hoist is fitted with an upper limit switch and end of rope sensor. The hoist is also fitted with an overload alarm that   can be set to stall to prevent injury should the equipment or person get caught / snagged while being hoisted. The load at which the hoist will stall must be factory set and can be chosen by the customer.

Inappropriate Application

The man-riding gantry system is to be used for lifting of persons, with a maximum total weight of 136kg with 2m span inside the legs of gantry and for lifting materials to a maximum capacity of 500kg while also providing fall arrest protection. Materials cannot be lifted by the powered man-riding hoist or rescue hoist and materials cannot be lifted when the system is being used for man-riding purposes. Man-riding and materials handling must be independent operations.

LiftingSafety Review:
Mainly used for height safety applications this mobile gantry is perfectly suited to lifting operations around wet wells; pump maintenance and inspections while providing restraint and fall protection for the operator (mainly supplied to Water Authorities). Easy to dismantle and fit into a van the gantry can be assembled by a two persons. Providing fall arrest  anchorage points overhead means that the hoist operator and rescuer never needs to be subjected to a potential fall situation (Therefore; potentially a rescue plan is not required for the operator). For situations that fall restraint is not practical the fall arrest points are used with a fall arrest inertia reel; for restraint use an adjustable restraint lanyard.
